+                      Release: WSJT-X 2.7.0-rc4
+                           March 11, 2024
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 4 brings some improvements for Fox-mode
+operators, new features for companion program QMAP, and a number of
+relatively minor enhancements and bug fixes.
+
+QMAP enhancements -- of particular interest to EME operators:
+
+ - QMAP now decodes Q65 submodes with both 60-second and 30-second T/R
+   sequence lengths. Clicking on a resulting line in the WSJT-X Active
+   Stations window automatically sets dial frequency and working
+   submode as needed to call that station.
+
+ - QMAP operates in 60-second receive sequences, and its Q65 decoder
+   starts at t=19.5, 30.0, 49.5, and 58.5 s into the sequence.  Most
+   decoded messages are displayed well before the end of the relevant
+   time slot.
+
+ - A new, more compact file format is now used for wideband data
+   files.  A "Save decoded" option has been added to the Save menu.
+
+ - An option has been added to allow exporting a 3 kHz portion of a
+   wideband data file as a standard WSJT-X *.wav file.
+
+ - CTRL+click on QMAP's upper waterfall sends an integer kHz dial
+   frequency request to WSJT-X.
+
+ - With focus on the WSJT-X main window, hit Alt+A on the keyboard to
+   clear the Active Stations window.
+
+ - Many minor enhancements to the User Interface.
+
+WSJT-X:
+
+ - Enable decoding of MSK144 from the jt9[.exe] executable.
+
+ - Several changes to reduce problems experienced when (contrary to
+   our recommendations) messages with short (10-bit) callsign hashes
+   are used in standard FT4/FT8 sub-bands.
+
+                      Release: WSJT-X 2.7.0-rc3
+                           January 1, 2024
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 3 brings some new features, as well as 
+numerous detail improvements and bug fixes, such as:
+
+ - Added a new "Update Hamlib" function. On Windows, it allows the user to 
+   update Hamlib directly from the program. The previously used version is 
+   backed up, so the user can easily revert a hamlib update. 
+
+ - The Hamlib version in use is now displayed (also on Linux and macOS).
+
+ - The FT Roundup Messages protocol has been enhanced. It now allows also 
+   the exchange of static 4-digit numbers instead of serial numbers. This 
+   extends the usability of the FT RU protocol for other contest types.
+
+ - Improved direct switching between modes. Submode, as well as the status 
+   of the "Sh" and "Fast" checkboxes are now saved and restored by mode.
+
+ - Some right-click events were made more intuitive and consistent. 
+   - Right-clicking the Q65 button enables Q65 Pileup mode, a left-click 
+     brings you back to the normal Q65 mode.
+   - Right-click the JT65 button to switch to JT9 mode.
+
+ - For Q65, all messages for us are now displayed in the right window.
+
+ - Message averaging is now allowed only when VHF features are
+   enabled, and label texts are changed to "Single Period Decodes" and
+   "Average Decodes" only if averaging is enabled.
+
+ - Some improvements to the Hamlib Transceiver code. Behavior is now
+   more stable when Rig Split has been selected.
+
+ - Prevented redundant network communication between WSJT-X and DX Lab 
+   Suite Commander.
+
+ - Download of the LotW file now works without OpenSSL libraries.
+
+ - Made the spot counter work for WSPR.
+
+ - Prevented insertion of an individual contest name when in Fox mode.
+
+ - WAE entities are now assigned to the correct DXCC when "Include 
+   extra WAE entities" is not selected.
+
+ - Added a utility program 'cablog' which can be used to convert the
+   wsjtx.log file to Cabrillo format for the ARRL EME contest.
+
+ - Minor improvements to the Active Stations window.
+
+ - The Rx/Tx frequency for Echo mode has been fixed at 1500 Hz.
+
+ - Some corrections and updates to the INSTALL instructions for Linux.
+
+ - Updated CTY.DAT file.
+
+                      Release: WSJT-X 2.7.0-rc2
+                             July 7, 2023
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 2 introduces several minor improvements
+and bug fixes.
+
+ - CTRL+SHIFT+F11/F12 now changes dial frequency by 1000 Hz instead of
+   2000 Hz.
+
+ - Improved spotting to PSK Reporter for upcoming HamSCI Festivals of
+   Eclipse Ionospheric Science.
+
+ - Added optional Hungarian translation of the user interface.
+
+ - Fixed a flaw that could produce false decodes in Q65 submodes D and E.
+
+ - Fixed a flaw with the QSO start time. It is now reset when the DX 
+   Call changes.
+
+ - Fixed a flaw that prevented contest logging of the ARRL Digi Contest.
+
+ - Right-clicking the Q65 mode button to toggle the Q65 Pileup mode on/off 
+   now also works on macOS.
+
+ - Fixed a compilation error on macOS Ventura.
+
+ - WSPR and FST4W band hopping now works again.
+
+ - It is now ensured that "U.S.A." is displayed when using certain 
+   cty.dat files.
+
+ - Corrected the problem with duplicated FT8 entries in ActiveStations 
+   window.
+
+                      Release: WSJT-X 2.7.0-rc1
+                             May 12, 2023
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 1 introduces a new program called QMAP,
+a new Special Operating Activity known as Q65 Pileup, and a number of
+other enhancements and fixes.
+
+ - QMAP and Q65 Pileup mode are of particular interest to those
+   engaged in Earth-Moon-Earth (EME) communication, but other
+   applications may be found for them as well.
+
+   - QMAP is derived from MAP65, an older program used since 2007 for
+     EME, mainly on the 2 m band. QMAP provides single-polarization
+     receive-only capabilities for any one of the 60-second submodes
+     of Q65. It allows you to monitor all traffic in a 90 kHz subband
+     while conducting EME QSOs in the usual way with WSJT-X.
+
+   - Q65 Pileup mode is a new feature in WSJT-X that will assist DX
+     operators using Q65 in pileup circumstances with many
+     simultaneous callers and very weak signals, such as those
+     experienced by 6-meter EME DXpeditions.
+
+   - Further details on QMAP and Q65 Pileup mode are available in a
+     Quick-Start guide posted here:
+     https://wsjt.sourceforge.io/Quick_Start_WSJT-X_2.7_QMAP.pdf
+
+ - WSJT-X now provides more efficient spotting to PSK Reporter.
+   Redundant spots are omitted, and posting of spots is now spread
+   more widely in time. (Temporarily, in support of the HamSCI
+   Festivals of Eclipse Ionospheric Science, spots will be transmitted
+   more frequently during the upcoming solar eclipses.)
+
+ - WSJT-X is now able to process more than 100 FT8 decodes in a single
+   reception interval.
+
+ - Improvements to the Fox mode:
+   - More convenient and efficient handling of the two queues.
+   - Fox Log window now displays statistical data on the QSO rate.
+
+ - When the station locator is changed (e.g during portable
+   operations), the new locator will be sent automatically to PSK
+   Reporter.
+
+ - The cty.dat file can now be updated by clicking a button on the
+   Settings -> Colors tab.
+
+ - A new status display appears when fetching a new LotW file.
+
+ - Multi-streamed messages transmitted by MSHV are now handled
+   properly when WSJT-X is in Hound mode.
+
+ - Auto-sequencing now has better protection against unwanted effects
+   caused by late FT8 decodes.
+
+ - Fixed an inconsistency in which Contest Name was not correctly
+   remembered.
+
+ - Other minor bug fixes.
+
+ - Updated hyperlinks to our homepage and to our new WSJT GROUP User
+   Forum (https://groups.io/g/wsjtgroup/) can now also be found in the
+   User Guide.
+
+ - The build instructions for macOS have been clarified.

+
+                      Release: WSJT-X 2.6.0-rc5
+                          November 29, 2022
+                      -------------------------
+
+WSJT-X 2.6.0 Release Candidate 5 brings a number of improvements as
+well as some bug fixes.
+
+In program WSJT-X:
+
+ - Better calibration for FST4/W SNR estimates.
+
+ - Upload FST4W-900 spots to wsprnet with TR code 15 instead of 16.
+
+ - Improved FT8 decoding on crowded bands. 
+
+ - The Working frequency table now offers the following options:
+   - Better handling of more than one frequency per band.
+   - Set your preferred frequencies, WSJT-X always comes back to these
+     QRGs when changing band or mode.
+   - You can label your frequencies with descriptions (e.g. DXp AB0YXZ).
+   - Option to set Start and End Date/Time, so that the frequencies 
+     automatically appear and disappear. Useful for contest or 
+     DXpedition QRGs.
+   - Load a frequency table from a file to easily get all such data 
+     implemented.
+
+ - In Fox mode, there are now a few additional functions that allow 
+   operators to react even better to different QSO situations:
+   - A new two-column table in Tab 2 provides a better overview of 
+     the queue and of the callsigns with QSOs in progress.
+   - Fox operator can now change the ordering of callsigns in the
+     queue so that he can react if there is only a narrow time slot
+     for a particular QSO due to propagation.
+   - Fox now responds for another two cycles to stations whose 
+     report was not received, increasing the success rate for a
+     difficult QSO.
+
+ - Correct a flaw in Hound mode that sometimes prevented completion of
+   QSOs with non-standard calls.
+
+ - Improvements to EME Echo mode:
+   - New control "Avg" sets the number of Echo cycles to be averaged.
+   - New capability to display measurements of wideband noise power as
+     a function of time.  This can be useful for measuring Sun noise,
+     antenna tracking errors, and the like.
+   - Several minor bug fixes
+
+ - Correct a flaw that prevented WSJT-X from always initializing 
+   correctly when special operating activities were enabled.
+
+ - Correct a flaw that caused wrong Tx frequencies to be written to  
+   ALL.TXT.
+
+ - The GUI has been improved regarding some details. The controls now 
+   scale better at different font sizes and on different operating 
+   systems.
+
+ - When in Hound mode and click the "H" button again, the frequency 
+   is now kept. This gives the user the following two options to return 
+   to normal FT8 mode:
+    - Click the "H" button again. Then you will stay on the QRG.
+    - Click the "FT8" button (or use the Settings menu). It brings  
+      you back to the default FT8 QRG.
+
+ - Decodes flagged as 'a7' are now disabled when "Enable AP" is not
+   checked, and during the first period after a band change.
+
+ - The network address of the UDP server is now checked for errors  
+   before being accepted.
+
+ - Some improvements to the DX Lab Suite Commander interface. 
+
+ - Correct some possible flaws that could cause segfault errors in 
+   certain unusual situations.
+
+ - Warnings on dropped audio have been disabled for now, as detection  
+   has turned out to be not reliable enough.
+
+ - Correct a long-standing flaw which caused the "Transmit digital gain" 
+   overlay to appear somewhere on the screen.
+
+ - "Highlight DX Call" now also works when the other station is <...>.
+
+ - CQ messages without a grid are now sent to PSK reporter.
+
+ - Several other minor corrections (tool tips, etc.). 
+
+Program MAP65 (Windows only) includes several minor bug fixes and two 
+tentative new features:
+ - an aid for measuring antenna pointing errors
+ - an ability to read the file wsjtx.log (kept by WSJT-X) to recognize
+   EME contest dupes.
+
+
+                      Release: WSJT-X 2.6.0-rc4
+                          September 8, 2022
+                      -------------------------
+
+WSJT-X 2.6.0 Release Candidate 4 provides further improvements to Echo 
+mode, a new File menu item, and several bug fixes.
+
+ - New features and fixes for Echo mode
+   - Created a new simulator echosim[.exe]
+   - Improved organization of output to text window
+   - Gain and Zero controls in Echo Graph now behave independently
+   - "Clear Avg" now erases the plot in Echo Graph
+   - Optional baseline for plots in Echo Graph
+
+ - New menu item "File | Copy main text window to WSJT-X.txt"
+ - Doppler tracking checkbox is made sticky
+
+ - Fix an RC2 bug that prevented normal use of JT9.

+
+	        Release: WSJT-X 2.6.0-rc3
+	             August 22, 2022
+	        ----------------------
+
+WSJT-X 2.6.0 Release Candidate 3 provides improvements to Echo mode and
+several bug fixes.
+
+ - Echo mode now allows audio-frequency corrections rather than
+   CAT-controlled resetting of dial frequency for Doppler corrections,
+   when Doppler shift is less than 750 Hz.  Audio-frequency
+   corrections are also used to correct any remaining portion of
+   Doppler shift caused by coarse CAT-controlled frequency setting.
+
+ - Echo mode now saves .wav files when "Save all" is selected.  When
+   such files are opened in Echo mode, the astronomical parameters at
+   recording time are restored and used for processing the Echo data.
+
+ - A missing Leap Second (January 1, 2017) was added to the code that
+   converts UTC to UT1.  This detail might matter if you want full
+   accuracy EME Doppler corrections.
+
+ - EME Doppler values are now rounded to nearest integer Hz.
+
+ - For backward compatibility, "Special Operating Activity"
+   enumerations for Fox and Hound modes are reset to their previous
+   values 6 and 7.
+
+ - Allow FST4W transmissions on 30m band.  Ensure that correct
+   frequency is reported to WSPRnet for FST4W decodes with Rx Freq
+   spinbox not set to 1500.
+
+ - Fix a bug that could truncate WSPR transmissions early.
+
+ - Fix a bug that occasionally caused a crash when 'decoded.txt'
+   could not be opened.
+
+ - Fix a bug that could cause a crash if Astronomical Data window
+   is not active when needed.
+
+ - Fix a bug that caused a crash when "Reset Cabrillo Log" is
+   selected with Active Stations window not active.
+
+
+	        Release: WSJT-X 2.6.0-rc2
+	             July 21, 2022
+	        ----------------------
+
+WSJT-X 2.6.0 Release Candidate 2 brings a number of improvements as
+well as some bug fixes.
+
+ - The "Measure" function in Echo mode now uses the computed Doppler
+   spread for DX grid, when available.  This feature is especially
+   helpful for microwave EME tests, enabling accurate measurement of
+   SNR for a DX station.
+
+ - Settings for T/R period and Submode are now remembered by mode when
+   you switch directly between (for example) MSK144-15, Q65-60A,
+   JT65C, or FST4-120.
+
+ - Tx and Rx audio frequencies are remembered and restored when you
+   return from a mode that sets a default frequency of 1500 Hz
+   (MSK144, FST4W, Echo, WSPR, FreqCal) and then switching back to
+   FT4, FT8, Q65, JT65, or FST4.
+
+ - QSOs in the Contest Log can now be displayed in increasing or
+   decreasing order of logged time.  By default the log is scrolled to
+   the latest logged QSO, ready for insertion of a new contact.  The
+   total number of QSOs in the Contest Log is displayed at bottom left
+   of its window.
+
+ - Default FT8 frequency for 4m band (Region 1) is set to 70.154 MHz.
+
+ - Layout of mode buttons has been optimized for 4K screens.
+
+ - Display of Keyboard Shortcuts has been updated.
+
+ - The OK button now has default focus in the LogQSO dialog window.
+   You may just hit Enter to log the QSO.
+
+-  Bug fix: The Tx Freq spinbox remained red when coming back from
+   some Q65 submodes.  Corrected.
+
+ - Hamlib bug fixes: make sure that VFOB is selected when required on
+   some rigs (e.g. IC7610, IC7100), and others.

+
+
+	        Release: WSJT-X 2.5.2
+	             Nov 4, 2021
+	        ----------------------
+
+This is mostly a bug fix  release.  It has the following changes since
+release 2.5.1:
+
+ - Repair a  longstanding regression  that caused signal  reports from
+   tail-ended Tx2 messages to be omitted from logged information
+
+ - Parse   "dx-call-1 RR73; dx-call-2 <de-call> +nn"  messages  (i3=0,
+   n3=1 DXpedition mode) in regular 77-bit modes
+
+ - Repair a regression  associated with setting the  main window width
+   on program startup.
+
+ - Repair a problem with Q65 decodes  of type 'q3' for messages of the
+   form "<Call_1> Call_2"
+
+ - Execute code associated with Q65 decodes of type 'q5' only when the
+   Max   Drift   control   is   set  to   50.    This   fix   prevents
+   double-incrementing of  the message averaging counter  on the first
+   decoding sequence.
+
+ - Polarization offset 'Dpol' from the astronomical data window is now
+   written    to    file     azel.dat    if    environment    variable
+   WSJT_AZEL_EXTRA_LINES has  been defined as  1 or greater.   Dpol is
+   especially useful for EME on the higher microwave bands.
+
+ - The Auto  Log QSO option  in "Settings->Reporting" now  behaves the
+   same  as  the Prompt  to  log  QSO option  when  not  in a  special
+   operating context mode.
+
+ - The Fast/Normal/Deep  setting in  Q65 mode is  now a sticky setting
+   and is no longer reset to Fast on program startup or  when Settings
+   has  been opened. The user selection is used for automatic decodes,
+   but Deep is used for any subsequent manual decode attempts.
+
+ - New hamlib code to correct minor flaws in controlling several rigs.
+
+ - Update  the  Chinese  and  Hong   Kong  translations  of  the  user
+   interface.
+
+ - Note  that since  the WSJT-X  v2.5.0 GA  release we  have not  been
+   providing pre-built 32-bit  packages for Linux on  Intel CPUs, this
+   is  due to  the mainstream  Linux Desktop  distributions no  longer
+   providing updates for 32-bit only  systems. 32-bit WSJT-X can still
+   be  built for  Linux Intel  and is  supported at  least until  some
+   prerequisite package is no longer available.
+
+   
+	        Release: WSJT-X 2.5.1
+	             Oct 21, 2021
+	        ----------------------
+
+This release mainly contains improvements and defect repairs related
+to Q65 and JT65 modes when used with non-standard and compound
+calls. Also included is a new feature for microwave aircraft scatter
+and repairs for defects detected since the 2.5.0 GA release.
+
+ - Improved Q65 support for 10GHz Aircraft Scatter contributed by Rex,
+   VK7MO, and Roger, W3SZ. (See "10 GHz Terrestrial with Q65" in DUBUS
+   Vol 1/2021 page 64.)  Decodes of type 'q3' may now include
+   corrections for frequency drift.
+
+ - Repair a defect that failed to pre-load the DE and DX calls to the
+   hash lookup tables in the Q65 decoder.
+
+ - Repair standard message Tx4 and Tx5 generation in Q65 mode when
+   using a non-standard call.
+
+ - Repair a defect in generation of the standard Tx2 JT65 message in

+
+ - Enable 'q3' AP decoding in Q65 mode for messages containing a
+   non-standard call.
+
+ - Repair a defect that required a blank DX Grid to achieve Q65 'q3'
+   decodes of messages containing a non-standard call.
+
+ - Repair the logic that sets parameters for Q65 "Deep" decoding.
+
+ - In Q65 mode, allow 'q2' decodes when MyCall is compound or

+FT8, JT4, JT9, JT65, Q65, FST4, MSK144, WSPR, FST4W, and Echo. The
 first seven are designed for making reliable QSOs under weak-signal

-JT65, including better performance on the very weakest signals. We
-imagine that over time it may replace JT65 for EME use. JT9 was
-originally designed for the LF, MF, and lower HF bands. Its submode
-JT9A is 2 dB more sensitive than JT65 while using less than 10% of the
-bandwidth. JT4 offers a wide variety of tone spacings and has proven
-highly effective for EME on microwave bands up to 24 GHz. These four
-“slow” modes use one-minute timed sequences of alternating
-transmission and reception, so a minimal QSO takes four to six minutes
-— two or three transmissions by each station, one sending in odd UTC
-minutes and the other even. FT8 is operationally similar but four
-times faster (15-second T/R sequences) and less sensitive by a few
-dB. FT4 is faster still (7.5 s T/R sequences) and especially well
-suited for radio contesting. On the HF bands, world-wide QSOs are

+EME use, it has also proved to be very effective for iono-scatter

+                      Release: WSJT-X 2.7.0-rc4
+                           March 11, 2024
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 4 brings some improvements for Fox-mode
+operators, new features for companion program QMAP, and a number of
+relatively minor enhancements and bug fixes.
+
+QMAP enhancements -- of particular interest to EME operators:
+
+ - QMAP now decodes Q65 submodes with both 60-second and 30-second T/R
+   sequence lengths. Clicking on a resulting line in the WSJT-X Active
+   Stations window automatically sets dial frequency and working
+   submode as needed to call that station.
+
+ - QMAP operates in 60-second receive sequences, and its Q65 decoder
+   starts at t=19.5, 30.0, 49.5, and 58.5 s into the sequence.  Most
+   decoded messages are displayed well before the end of the relevant
+   time slot.
+
+ - A new, more compact file format is now used for wideband data
+   files.  A "Save decoded" option has been added to the Save menu.
+
+ - An option has been added to allow exporting a 3 kHz portion of a
+   wideband data file as a standard WSJT-X *.wav file.
+
+ - CTRL+click on QMAP's upper waterfall sends an integer kHz dial
+   frequency request to WSJT-X.
+
+ - With focus on the WSJT-X main window, hit Alt+A on the keyboard to
+   clear the Active Stations window.
+
+ - Many minor enhancements to the User Interface.
+
+WSJT-X:
+
+ - Enable decoding of MSK144 from the jt9[.exe] executable.
+
+ - Several changes to reduce problems experienced when (contrary to
+   our recommendations) messages with short (10-bit) callsign hashes
+   are used in standard FT4/FT8 sub-bands.
+
+                      Release: WSJT-X 2.7.0-rc3
+                           January 1, 2024
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 3 brings some new features, as well as 
+numerous detail improvements and bug fixes, such as:
+
+ - Added a new "Update Hamlib" function. On Windows, it allows the user to 
+   update Hamlib directly from the program. The previously used version is 
+   backed up, so the user can easily revert a hamlib update. 
+
+ - The Hamlib version in use is now displayed (also on Linux and macOS).
+
+ - The FT Roundup Messages protocol has been enhanced. It now allows also 
+   the exchange of static 4-digit numbers instead of serial numbers. This 
+   extends the usability of the FT RU protocol for other contest types.
+
+ - Improved direct switching between modes. Submode, as well as the status 
+   of the "Sh" and "Fast" checkboxes are now saved and restored by mode.
+
+ - Some right-click events were made more intuitive and consistent. 
+   - Right-clicking the Q65 button enables Q65 Pileup mode, a left-click 
+     brings you back to the normal Q65 mode.
+   - Right-click the JT65 button to switch to JT9 mode.
+
+ - For Q65, all messages for us are now displayed in the right window.
+
+ - Message averaging is now allowed only when VHF features are
+   enabled, and label texts are changed to "Single Period Decodes" and
+   "Average Decodes" only if averaging is enabled.
+
+ - Some improvements to the Hamlib Transceiver code. Behavior is now
+   more stable when Rig Split has been selected.
+
+ - Prevented redundant network communication between WSJT-X and DX Lab 
+   Suite Commander.
+
+ - Download of the LotW file now works without OpenSSL libraries.
+
+ - Made the spot counter work for WSPR.
+
+ - Prevented insertion of an individual contest name when in Fox mode.
+
+ - WAE entities are now assigned to the correct DXCC when "Include 
+   extra WAE entities" is not selected.
+
+ - Added a utility program 'cablog' which can be used to convert the
+   wsjtx.log file to Cabrillo format for the ARRL EME contest.
+
+ - Minor improvements to the Active Stations window.
+
+ - The Rx/Tx frequency for Echo mode has been fixed at 1500 Hz.
+
+ - Some corrections and updates to the INSTALL instructions for Linux.
+
+ - Updated CTY.DAT file.
+
+                      Release: WSJT-X 2.7.0-rc2
+                             July 7, 2023
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 2 introduces several minor improvements
+and bug fixes.
+
+ - CTRL+SHIFT+F11/F12 now changes dial frequency by 1000 Hz instead of
+   2000 Hz.
+
+ - Improved spotting to PSK Reporter for upcoming HamSCI Festivals of
+   Eclipse Ionospheric Science.
+
+ - Added optional Hungarian translation of the user interface.
+
+ - Fixed a flaw that could produce false decodes in Q65 submodes D and E.
+
+ - Fixed a flaw with the QSO start time. It is now reset when the DX 
+   Call changes.
+
+ - Fixed a flaw that prevented contest logging of the ARRL Digi Contest.
+
+ - Right-clicking the Q65 mode button to toggle the Q65 Pileup mode on/off 
+   now also works on macOS.
+
+ - Fixed a compilation error on macOS Ventura.
+
+ - WSPR and FST4W band hopping now works again.
+
+ - It is now ensured that "U.S.A." is displayed when using certain 
+   cty.dat files.
+
+ - Corrected the problem with duplicated FT8 entries in ActiveStations 
+   window.
+
+                      Release: WSJT-X 2.7.0-rc1
+                             May 12, 2023
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 1 introduces a new program called QMAP,
+a new Special Operating Activity known as Q65 Pileup, and a number of
+other enhancements and fixes.
+
+ - QMAP and Q65 Pileup mode are of particular interest to those
+   engaged in Earth-Moon-Earth (EME) communication, but other
+   applications may be found for them as well.
+
+   - QMAP is derived from MAP65, an older program used since 2007 for
+     EME, mainly on the 2 m band. QMAP provides single-polarization
+     receive-only capabilities for any one of the 60-second submodes
+     of Q65. It allows you to monitor all traffic in a 90 kHz subband
+     while conducting EME QSOs in the usual way with WSJT-X.
+
+   - Q65 Pileup mode is a new feature in WSJT-X that will assist DX
+     operators using Q65 in pileup circumstances with many
+     simultaneous callers and very weak signals, such as those
+     experienced by 6-meter EME DXpeditions.
+
+   - Further details on QMAP and Q65 Pileup mode are available in a
+     Quick-Start guide posted here:
+     https://wsjt.sourceforge.io/Quick_Start_WSJT-X_2.7_QMAP.pdf
+
+ - WSJT-X now provides more efficient spotting to PSK Reporter.
+   Redundant spots are omitted, and posting of spots is now spread
+   more widely in time. (Temporarily, in support of the HamSCI
+   Festivals of Eclipse Ionospheric Science, spots will be transmitted
+   more frequently during the upcoming solar eclipses.)
+
+ - WSJT-X is now able to process more than 100 FT8 decodes in a single
+   reception interval.
+
+ - Improvements to the Fox mode:
+   - More convenient and efficient handling of the two queues.
+   - Fox Log window now displays statistical data on the QSO rate.
+
+ - When the station locator is changed (e.g during portable
+   operations), the new locator will be sent automatically to PSK
+   Reporter.
+
+ - The cty.dat file can now be updated by clicking a button on the
+   Settings -> Colors tab.
+
+ - A new status display appears when fetching a new LotW file.
+
+ - Multi-streamed messages transmitted by MSHV are now handled
+   properly when WSJT-X is in Hound mode.
+
+ - Auto-sequencing now has better protection against unwanted effects
+   caused by late FT8 decodes.
+
+ - Fixed an inconsistency in which Contest Name was not correctly
+   remembered.
+
+ - Other minor bug fixes.
+
+ - Updated hyperlinks to our homepage and to our new WSJT GROUP User
+   Forum (https://groups.io/g/wsjtgroup/) can now also be found in the
+   User Guide.
+
+ - The build instructions for macOS have been clarified.
+
+
+                        Release: WSJT-X 2.6.1
+                           January 16, 2023
+                      -------------------------
+
+WSJT-X 2.6.1 is mostly a bug fix release for Q65.  It has the following  
+changes since release 2.6.0:
+
+ - Fix a flaw in Q65 mode that prevented proper display of the T/R 
+   period spinner.
+
+ - Make the initialization of the decoded text font more robust.
+
+ - Better initialization when starting the program in FT8 Hound mode.
+
+ - Fix a bug causing program crash with more than 100 decodes in a

+
+                      Release: WSJT-X 2.6.0-rc5
+                          November 29, 2022
+                      -------------------------
+
+WSJT-X 2.6.0 Release Candidate 5 brings a number of improvements as
+well as some bug fixes.
+
+In program WSJT-X:
+
+ - Better calibration for FST4/W SNR estimates.
+
+ - Upload FST4W-900 spots to wsprnet with TR code 15 instead of 16.
+
+ - Improved FT8 decoding on crowded bands. 
+
+ - The Working frequency table now offers the following options:
+   - Better handling of more than one frequency per band.
+   - Set your preferred frequencies, WSJT-X always comes back to these
+     QRGs when changing band or mode.
+   - You can label your frequencies with descriptions (e.g. DXp AB0YXZ).
+   - Option to set Start and End Date/Time, so that the frequencies 
+     automatically appear and disappear. Useful for contest or 
+     DXpedition QRGs.
+   - Load a frequency table from a file to easily get all such data 
+     implemented.
+
+ - In Fox mode, there are now a few additional functions that allow 
+   operators to react even better to different QSO situations:
+   - A new two-column table in Tab 2 provides a better overview of 
+     the queue and of the callsigns with QSOs in progress.
+   - Fox operator can now change the ordering of callsigns in the
+     queue so that he can react if there is only a narrow time slot
+     for a particular QSO due to propagation.
+   - Fox now responds for another two cycles to stations whose 
+     report was not received, increasing the success rate for a
+     difficult QSO.
+
+ - Correct a flaw in Hound mode that sometimes prevented completion of
+   QSOs with non-standard calls.
+
+ - Improvements to EME Echo mode:
+   - New control "Avg" sets the number of Echo cycles to be averaged.
+   - New capability to display measurements of wideband noise power as
+     a function of time.  This can be useful for measuring Sun noise,
+     antenna tracking errors, and the like.
+   - Several minor bug fixes
+
+ - Correct a flaw that prevented WSJT-X from always initializing 
+   correctly when special operating activities were enabled.
+
+ - Correct a flaw that caused wrong Tx frequencies to be written to  
+   ALL.TXT.
+
+ - The GUI has been improved regarding some details. The controls now 
+   scale better at different font sizes and on different operating 
+   systems.
+
+ - When in Hound mode and click the "H" button again, the frequency 
+   is now kept. This gives the user the following two options to return 
+   to normal FT8 mode:
+    - Click the "H" button again. Then you will stay on the QRG.
+    - Click the "FT8" button (or use the Settings menu). It brings  
+      you back to the default FT8 QRG.
+
+ - Decodes flagged as 'a7' are now disabled when "Enable AP" is not
+   checked, and during the first period after a band change.
+
+ - The network address of the UDP server is now checked for errors  
+   before being accepted.
+
+ - Some improvements to the DX Lab Suite Commander interface. 
+
+ - Correct some possible flaws that could cause segfault errors in 
+   certain unusual situations.
+
+ - Warnings on dropped audio have been disabled for now, as detection  
+   has turned out to be not reliable enough.
+
+ - Correct a long-standing flaw which caused the "Transmit digital gain" 
+   overlay to appear somewhere on the screen.
+
+ - "Highlight DX Call" now also works when the other station is <...>.
+
+ - CQ messages without a grid are now sent to PSK reporter.
+
+ - Several other minor corrections (tool tips, etc.). 
+
+Program MAP65 (Windows only) includes several minor bug fixes and two 
+tentative new features:
+ - an aid for measuring antenna pointing errors
+ - an ability to read the file wsjtx.log (kept by WSJT-X) to recognize
+   EME contest dupes.

+
+	        Release: WSJT-X 2.6.0-rc3
+	             August 22, 2022
+	        ----------------------
+
+WSJT-X 2.6.0 Release Candidate 3 provides improvements to Echo mode and
+several bug fixes.
+
+ - Echo mode now allows audio-frequency corrections rather than
+   CAT-controlled resetting of dial frequency for Doppler corrections,
+   when Doppler shift is less than 750 Hz.  Audio-frequency
+   corrections are also used to correct any remaining portion of
+   Doppler shift caused by coarse CAT-controlled frequency setting.
+
+ - Echo mode now saves .wav files when "Save all" is selected.  When
+   such files are opened in Echo mode, the astronomical parameters at
+   recording time are restored and used for processing the Echo data.
+
+ - A missing Leap Second (January 1, 2017) was added to the code that
+   converts UTC to UT1.  This detail might matter if you want full
+   accuracy EME Doppler corrections.
+
+ - EME Doppler values are now rounded to nearest integer Hz.
+
+ - For backward compatibility, "Special Operating Activity"
+   enumerations for Fox and Hound modes are reset to their previous
+   values 6 and 7.
+
+ - Allow FST4W transmissions on 30m band.  Ensure that correct
+   frequency is reported to WSPRnet for FST4W decodes with Rx Freq
+   spinbox not set to 1500.
+
+ - Fix a bug that could truncate WSPR transmissions early.
+
+ - Fix a bug that occasionally caused a crash when 'decoded.txt'
+   could not be opened.
+
+ - Fix a bug that could cause a crash if Astronomical Data window
+   is not active when needed.
+
+ - Fix a bug that caused a crash when "Reset Cabrillo Log" is
+   selected with Active Stations window not active. 
+
+
+	        Release: WSJT-X 2.6.0-rc2
+	             July 21, 2022
+	        ----------------------
+
+WSJT-X 2.6.0 Release Candidate 2 brings a number of improvements as
+well as some bug fixes.
+
+ - The "Measure" function in Echo mode now uses the computed Doppler
+   spread for DX grid, when available.  This feature is especially
+   helpful for microwave EME tests, enabling accurate measurement of
+   SNR for a DX station.
+
+ - Settings for T/R period and Submode are now remembered by mode when
+   you switch directly between (for example) MSK144-15, Q65-60A,
+   JT65C, or FST4-120.
+
+ - Tx and Rx audio frequencies are remembered and restored when you
+   return from a mode that sets a default frequency of 1500 Hz
+   (MSK144, FST4W, Echo, WSPR, FreqCal) and then switching back to
+   FT4, FT8, Q65, JT65, or FST4.
+
+ - QSOs in the Contest Log can now be displayed in increasing or
+   decreasing order of logged time.  By default the log is scrolled to
+   the latest logged QSO, ready for insertion of a new contact.  The
+   total number of QSOs in the Contest Log is displayed at bottom left
+   of its window.
+
+ - Default FT8 frequency for 4m band (Region 1) is set to 70.154 MHz.
+
+ - Layout of mode buttons has been optimized for 4K screens.
+
+ - Display of Keyboard Shortcuts has been updated.
+
+ - The OK button now has default focus in the LogQSO dialog window.
+   You may just hit Enter to log the QSO.
+
+-  Bug fix: The Tx Freq spinbox remained red when coming back from
+   some Q65 submodes.  Corrected.
+
+ - Hamlib bug fixes: make sure that VFOB is selected when required on
+   some rigs (e.g. IC7610, IC7100), and others.

+ - Execute code associated with Q65 decodes of type 'q5' only when the
+   Max   Drift   control   is   set  to   50.    This   fix   prevents
+   double-incrementing of  the message averaging counter  on the first
+   decoding sequence.
+
+ - Polarization offset 'Dpol' from the astronomical data window is now
+   written    to    file     azel.dat    if    environment    variable
+   WSJT_AZEL_EXTRA_LINES has  been defined as  1 or greater.   Dpol is
+   especially useful for EME on the higher microwave bands.
+
+ - The Auto  Log QSO option  in "Settings->Reporting" now  behaves the
+   same  as  the Prompt  to  log  QSO option  when  not  in a  special
+   operating context mode.
+
+ - The Fast/Normal/Deep  setting in  Q65 mode is  now a sticky setting
+   and is no longer reset to Fast on program startup or  when Settings
+   has  been opened. The user selection is used for automatic decodes,
+   but Deep is used for any subsequent manual decode attempts.
+
+ - New hamlib code to correct minor flaws in controlling several rigs.
+
+ - Update  the  Chinese  and  Hong   Kong  translations  of  the  user
+   interface.
+
+ - Note  that since  the WSJT-X  v2.5.0 GA  release we  have not  been
+   providing pre-built 32-bit  packages for Linux on  Intel CPUs, this
+   is  due to  the mainstream  Linux Desktop  distributions no  longer
+   providing updates for 32-bit only  systems. 32-bit WSJT-X can still
+   be  built for  Linux Intel  and is  supported at  least until  some
+   prerequisite package is no longer available.
+
+   
+	        Release: WSJT-X 2.5.1
+	             Oct 21, 2021
+	        ----------------------
+
+This release mainly contains improvements and defect repairs related
+to Q65 and JT65 modes when used with non-standard and compound
+calls. Also included is a new feature for microwave aircraft scatter
+and repairs for defects detected since the 2.5.0 GA release.
+
+ - Improved Q65 support for 10GHz Aircraft Scatter contributed by Rex,
+   VK7MO, and Roger, W3SZ. (See "10 GHz Terrestrial with Q65" in DUBUS
+   Vol 1/2021 page 64.)  Decodes of type 'q3' may now include
+   corrections for frequency drift.
+
+ - Repair a defect that failed to pre-load the DE and DX calls to the
+   hash lookup tables in the Q65 decoder.
+
+ - Repair standard message Tx4 and Tx5 generation in Q65 mode when
+   using a non-standard call.
+
+ - Repair a defect in generation of the standard Tx2 JT65 message in
+   EME mode when using a compound call.
+
+ - Repair a defect when decoding 77-bit type 4 non-standard call
+   message.
+
+ - Repair a defect that could cause a crash when switching from Q65 to
+   JT65 mode and attempting a double-click decode.
+
+ - Enable 'q3' AP decoding in Q65 mode for messages containing a
+   non-standard call.
+
+ - Repair a defect that required a blank DX Grid to achieve Q65 'q3'
+   decodes of messages containing a non-standard call.
+
+ - Repair the logic that sets parameters for Q65 "Deep" decoding.
+
+ - In Q65 mode, allow 'q2' decodes when MyCall is compound or
+   non-standard.
+
+ - Repair a long-standing defect that could cause a crash when
+   reference spectrum correction is enabled.
+
+ - Updated UI translations from Xavi, EA3W, Oba-san, JA7UDE, and a new
+   translation for Traditional Chinese by Steven, BU2EL.
+
+ - Updated CTY.DAT database, tnx to Jim AD1C
+
+ - Improved main window layout to ensure TxN messages are fully
+   visible.

+	        Release: WSJT-X 2.5.0
+	              Sept 27, 2021
+	        -------------------------
+
+WSJT-X in  this release is nearly  identical to that in  WSJT-X 2.4.0.
+The Q65 decoder has been enhanced to measure and compensate for linear
+frequency drift in Q65 signals.  In addition, the Windows installation
+package now  includes version 3.0  of application MAP65 which  has Q65
+support to  match and improve  on its existing JT65  capabilities.
+
+See the 2.5.0  release candidate notices below for a  summaries of the
+other changes included  in this release. WSJT-X 2.5.0  is bundled with
+Hamlib version 4.3.1 which  includes important regression repairs over
+the earlier 4.3 release.
+
+Other  changes  in the  package  since  WSJT-X 2.5.0-rc6  include  the
+following enhancements and defect repairs:
+
+MAP65:
+ - Ensure that CALL3.TXT is not  deleted while updating the file (this
+   allows sharing using symlinks to work).
+ - Fix MAP65's generation of Tx3 message for abs(SNR)< 10.
+
+WSJTX:
+ - Repair a defect that caused CAT errors when using WSPR band hopping
+   and auto tune-up with some Icom rigs.
+ - Ensure that CALL3.TXT is not  deleted while updating the file (this
+   allows sharing using symlinks to work).
+
+
+	        Release: WSJT-X 2.5.0-rc6
+	              Sept 6, 2021
+	        -------------------------
+
+Remember that the WSJT-X 2.5.0 package includes MAP65 3.0.0.  Changes
+in the package since WSJT-X 2.5.0-rc5 include the following
+enhancements and defect repairs:
+
+MAP65:
+ - There are no functional changes to MAP65 in this release.
+ 
+WSJT-X:
+ - Repair a file handle leak in wsprd (tnx Phil, KA9Q).
+ - Better handling of the Tx1 buttons when changing special operating
+   modes.
+ - Q65 mode now supports contest special operating modes.
+ - Repair an issue when non-ASCII characters used in account names.
+ - Repair a regression that prevented WSPR band-hopping working when
+   the Tx percentage is zero.
+
+ 
+	        Release: WSJT-X 2.5.0-rc5

+	        -------------------------
+
+Remember that the WSJT-X 2.5.0 package includes MAP65 3.0.0.  Changes
+in the package since WSJT-X 2.5.0-rc4 include the following
+enhancements and defect repairs:
+
+MAP65:
+ - When you double-click on lower waterfall, Ftol is set to 100 
+   only if it is currently set to a higher value.
+ - Early decoding pass is skipped when data are read from disk.
+ - Duplicate decodes are suppressed only when at the same frequency.
+ 
+WSJT-X:
+ - Repair a regression that caused some messages involving compound
+   or nonstandard callsigns to be encoded as free text

-_WSJT-X 2.5.0_ introduces an enhanced Q65 decoder that measures and
-compensates for linear frequency drifts of Q65 signals.  Activate this
-feature by setting a spinner control *Max Drift* on the _WSJT-X_ main
-window to a number greater than 0.  We suggest a setting of 10 for
-submode Q65-60A, the recommended submode for EME on 50 and 144 MHz,
-which will accommodate drift rates up to 20 Hz/minute.  Similarly, we
-suggest *Max Drift* = 40 for submode Q65-15C, used for for 10 GHz QSOs
-(up to 900 km) via aircraft scatter and drift rates up to about 20
-Hz/s.
+_WSJT-X 2.7_ introduces a new program called *QMAP*, a new Special
+Operating Activity *Q65 Pileup*, an option to *Update Hamlib* at the
+click of a button, and a number of other enhancements and bug fixes.
+
+- QMAP and Q65 Pileup mode are of particular interest to those engaged
+  in Earth-Moon-Earth (EME) communication, but other applications may
+  be found for them as well.  QMAP is currently available for Windows
+  only; it is derived from MAP65, an older program used since 2007 for
+  EME. QMAP provides single-polarization receive-only capabilities for
+  any one of the 60-second submodes of Q65. It allows you to monitor
+  all traffic in a 90 kHz sub-band while conducting EME QSOs in the
+  usual way with _WSJT-X_.  Q65 Pileup mode helps DX operators using
+  Q65 in pileup circumstances with many simultaneous callers and very
+  weak signals, such as those experienced by 6-meter EME DXpeditions.
+  Further details on QMAP and Q65 Pileup mode are available in a
+  Quick-Start guide posted here:
+  https://wsjt.sourceforge.io/Quick_Start_WSJT-X_2.7_QMAP.pdf
+
+- A button *Update Hamlib* now appears on the *Settings -> Radio* tab.
+  On Windows it allows the user to automatically download and install
+  the latest version of the rig-control features in Hamlib.  The
+  previously used version is backed up, so you can easily revert the
+  procedure if necessary. Names and dates of the active and backup
+  versions are clearly displayed.
+
+- Spotting to *PSK Reporter* has been made more efficient.  Redundant
+  spots are omitted, and all posts are spread more widely in time. If
+  your station locator is changed, for example during portable
+  operations, your new locator will be sent automatically to PSK
+  Reporter.
+
+- *Fox* mode now provides more convenient handling of the two callsign
+  queues, and Fox's Log window displays statistical data on recent QSO
+  rate.  Multi-streamed messages transmitted by _MSHV_ are now handled
+  properly when _WSJT-X_ is in *Hound* mode.
+
+- The cty.dat file can now be updated by clicking a button on the
+  *Settings -> Colors* tab.
+
+- The FT Roundup message protocol now allows the exchange of static
+  4-digit numbers in place of serial numbers. This extends the
+  usability of the FT RU protocol for other contest types.
+
+- Features for main-window switching between modes have been enhanced
+  so that submode and status of the *Sh* and *Fast* checkboxes are
+  saved and restored by mode.  Right-click events were made more
+  intuitive and consistent.  Right-clicking the Q65 button enables Q65
+  Pileup mode, and a left-click brings you back to the normal Q65
+  mode.  Right-click on the JT65 button switches to JT9 mode.
+
+- Message averaging is now allowed only when *VHF features* are
+  enabled.  Main window text box labels are changed to read "`Single
+  Period Decodes`" and "`Average Decodes`" when averaging is enabled.

-On the Windows platform only, _WSJT-X 2.5.0_ installations now include
-an early version of _MAP65 3.0_.  This program works together with
-suitable hardware that converts RF to baseband.  The hardware/software
-combination implements a wideband, highly optimized receiver for the
-Q65 and JT65 protocols, with matching transmitting features that
-require a standard SSB transceiver.  _MAP65_ is effective in both
-single-polarization and dual-polarization systems.  If two
-polarization channels are available, _MAP65_ determines and matches
-the linear polarization angle of each decodable signal.  This
-capability provides a major advantage for efficient EME communication
-on bands up to 432 MHz.  A single-channel _MAP65_ system works
-extremely well for EME on 1296 MHz and higher bands, displaying all
-signals in a 90 kHz sub-band and decoding all the Q65 and JT65
-signals.

+.Decoding Overview
+
+Decoding takes place at the end of a receive sequence. With *Decode* set
+to *Deep*, three decoding passes will be done and the *Decode* button on the 
+mainwindow will illuminate three times, once for each pass. 
+The first decoding attempt in each decoding pass is done at the selected Rx frequency,
+indicated by the U-shaped green marker on the waterfall frequency
+scale. All decodes appear in the left (*Band Activity*) window. The right
+(*Rx Frequency*) text window displays any decodes obtained at the current
+Rx frequency along with any decodes addressed to *My Call* (K1JT in this case).
+The red marker on the waterfall scale indicates your
+Tx frequency.
+
+Twenty-one FT8 signals are decoded from the example file. The number
+of decodes is shown in a box at the bottom of the main window.
+When this file was recorded HA5WA was finishing a QSO with K1JT, and
+his 73 message is shown in red because it is addressed to *My Call* (in this case K1JT). 
+By default, lines containing `CQ`
+are highlighted in green, and lines with *My Call* (K1JT)
+in red. Notice that K1JT has two callers; HA0DU and EA3AGB.  
+
+[[X13]]
+.Decoding Controls
+
+To gain some feeling for controls frequently used when making QSOs,
+try double-clicking with the mouse on the decoded text lines and on the
+waterfall spectral display. You should be able to confirm the
+following behavior:
+
+- Double-click on one of the decoded *CQ* messages highlighted in
+green. These actions produce the following results:
+
+** Callsign and locator of the station calling CQ are copied to the *DX
+Call* and *DX Grid* entry fields. 
+
+** Messages are generated for a standard minimal QSO.
+
+** The *Tx even* box is checked or cleared appropriately, so that you
+will transmit in the proper (odd or even) minutes.
+
+** The Rx frequency marker is moved to the frequency of the CQing
+station.
+
+** You can modify the double-click behavior by holding down the
+*Shift* key to move only the Tx frequency or the *Ctrl* key to move
+both Rx and Tx frequencies. (On a Mac computer, use the *command* key
+instead of *Ctrl*). 
+
+** In addition, if *Double-click on call sets Tx enable* is checked on the 
+*Settings | General* tab then *Enable Tx* will be activated
+so that a transmission will start automatically at the proper time.

+frequency (red marker) is not moved unless *Shift* or *Ctrl* is held

+Joe Taylor, K1JT:
+
+I am very sorry to convey the sad news that Bill Somerville,
+G4WJS, died suddenly and unexpectedly a few days ago.  He was only
+about 65 years old.
+
+Bill was a dear friend and very close colleague, though (as is often
+the case with worldwide ham radio friendships) we had met in person
+only a few times.  In 2013 he was the first to join me in forming a
+core development group for WSJT-X, which at that time was at program
+version 0.99.  Bill has been closely involved with WSJT-X and related
+software projects ever since.
+
+Our free, open-source software could not have achieved its extensive
+worldwide popularity and influence in ham radio without Bill's
+essential contributions.  In addition to writing code for important
+portions of the Qt-based user interface for WSJT-X, Bill helped to
+bring the overall program structure more nearly up to professional
+standards.  Moreover, he devoted countless hours to program support,
+patiently answering user's questions on WSJT-related forums.
+
+I have only started to think about the many ways in which I will miss
+Bill -- not no mention how we all will miss his immense and positive
+impact on WSJT-X and related projects.  For more than eight years Bill
+and I communicated closely and regularly on ham radio topics,
+sometimes many times per day.  Perhaps I will be able to write more
+about it in the near future.
+
+Rest in peace, dear friend G4WJS.

+and me being a Photographer for The Sun Newspaper In London before I
+retired had another common interest we liked to have a good natter but
+I often came off the worst.Bill lived on his own so we kept a close
+eye on each other.

+He was a whizz. He was a great natural teacher and Joe I think this was
+one of the reasons he got on so well with you and the group.He
+remarked to me many times "I never mind helping anyone provided they
+help themselves" At times glaring at me muttering under his breath

+could not keep a straight face..we all know the story.Bill always
+willing to help with a computer grafted to his hand.  Over the last
+ten years he has like others in the group spent hours and hours
+involved with WSJX-X.He had a great admiration for open source
+programs.Made many friends within the digital community and a big
+respect for Dxlabs {Dave] JTalert [Laurie] among others. I was always
+giving him praise for taking a break and TXing winding up this 4 ele
+,of late not often[Bill head in PC} every day I would have a crafty
+check on his PSK. Bill was very much in favour of Using L.O.T.W but
+never collected awards,but on receiving a trophy for technical
+achievement announced at Dayton when he told me there was no emotion
+but I knew Bill just to well he was chuffed !

+community, whether or not they had ever had any direct dealings with
+Bill.
+
+Please convey all our sympathies and our deepest condolences to Bill's
+relatives and friends.
+
+John Nelson, G4KLA:
+
+I am saddened to learn of your news.  This is blow to the WSJT-X
+community.
+
+In the early days of Bill’s involvement with WSJT he often logged into
+my Macs at home to test his software modifications on a Mac until he
+got a VM working.  He and I had numerous discussions while testing new
+versions on various Mac OS.  He was generous with his time in helping
+folks with problems either running the codes or attempting to build
+the software on various platforms.  The multitude of emails to the
+development list is a tribute to his commitment to ensure that the
+various programs operated flawlessly.
+
+His involvement with the development of WSJT-X code especially with
+modernising the structure of the whole program has been immense.  I
+will certainly miss his advice.
+
+A sad day…
+
+Alan, G0TLK:
+
+Shocking and saddening news, he will be greatly missed.
+
+My condolences to his family and friends, and RIP Bill.
+
+Robin, G8DQX:
+
+I only knew Bill through his contributions to the WSJT lists. Those
+contributions were sharp, radical, and usually encouraging. He was a
+clearly essential part of a team that is helping Amateur Radio to
+grow, expand and develop, far beyond what you and I knew when,
+soldering iron in hand, we first played with radio, all those years
+ago.
+
+My condolences to his family and friends. We shall all miss him.
+
+Robin, G8DQX
+
+Charlie Suckling, G3WDG/DL3WDG:
+
+We were also shocked and very sorry to hear of Bill's sudden
+passing. I never had the pleasure of meeting him in person.  Like Bob,
+he attended the same University and read the same degree.
+
+We are so grateful for his contributions over many years to
+WSJT-X. His support for users was first class, and he even joined the
+EME reflectors to give support to EME users during the roll-out of
+Q65, despite not being active himself on EME.  He was contributing
+there regularly, and some of his last efforts were to support the use
+of WSJT-X for Doppler control on CW on the microwave bands.
+
+He was also a very patient and diligent teacher, tutoring and helping
+those who wished to make small contributions to the project. I am very
+grateful for the time he spent in such ways.
+
+Bill will surely be greatly missed, and sincere condolences to his
+family and many friends.
+
+RIP Bill.
+
+James Shaver, N2ADV:
+
+I had the pleasure of talking to Bill over Skype a few times during
+the development of 1.7 and later 1.8 to chase down some CAT control
+gremlins with several radios I happen to own. His patience and
+intelligence was incredible. Such a huge loss to us all.
+
+My sincerest condolences to his family and friends. 
+
+He will definitely be missed but his contributions to the advancement
+of amateur radio will live on indefinitely.
+
+Alessandro Gorobey, IK2
+
+Very sad news and a great loss.
+
+A great teacher.
+
+My sincerest condolences to his family and friends.
+
+Jim Preston, N6VH:
+
+This is definitely very sad news. Bill was a very important part of
+the WSJT team. He will be missed very much.
+
+My condolences to his family.
+
+Gary Lane, VK4OO
+
+Very sad news, my condolences to Bills friends and family….
+
+Bob Atkins, KA1GT:
+
+I was shocked and saddened by the news of Bill's passing.  We chatted
+on line quite often though we never met in person.  He attended the
+same university as I didn't, reading the same subjects, but was a hear
+of two behind me, so we never met their either. Bill will be greatly
+missed and I send my condolences to his friends and family.
+
+RIP Bill.
+
+Dave Schmocker, KJ9I:
+
+This is incredibly sad news.  Bill was always so helpful, highly
+responsive, and on-target with deep technical solutions.
+
+What a wonderful asset Bill was to the hobby and to all with whom he
+interfaced.
+
+Jim, WB4CGS:
+
+I am very sorry for this loss.
+
+Conrad Farlow, Jim WB4GCS
+
+Joe I am absolutely lost for words. What a terrible shock. I cannot
+imagine him not being there. My condolences to you, Bill's family and
+well the whole dev team. We will all miss him Most of all I am sorry
+that you lost such a good friend.
+
+Sam Jewell, G4DDK:
+
+So sad to hear this news. One of the team who have revolutionised ham
+radio operation, popularised digital and helped realise what we
+thought should be possible.
+
+Vale Bill.
+
+
+Nick, NN3Y:
+
+R I. P. Bill.  He'll be missed. My sincere condolences to his family
+and friends.
+
+
+Jay, KA9CFD:
+
+Shocking and very sorry news. RIP Bill.
+
+Mirek, OK2AQ:
+
+Very sad news  for us WSJT-X users. R.I.P. Bill
