 experimental) branch of the program _WSJT_.
 
-_WSJT-X_ currently offers two protocols or “modes,” JT65 and JT9.
-Both are designed for making reliable, confirmed QSOs under extreme
-weak-signal conditions. They use nearly identical message structure
-and source encoding.  JT65 was designed for EME (“moonbounce”) on the
-VHF/UHF bands and has also proven very effective for worldwide QRP

+The first three are designed for making reliable, confirmed QSOs under
+extreme weak-signal conditions. They use nearly identical message

+JT65 while using less than 10% of the bandwidth.  JT4 offers a wide
+variety of tone spacings and has proved very effective for EME on
+microwave bands up to 24 GHz.  All three of these 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. On
-the HF bands, world-wide QSOs are possible with power levels of a few
-watts and compromise antennas.

+possible (by EME and other propagation methods) at signal levels 10 to
+15 dB below those required for CW.
 
-_WSJT-X_ can display a passband as large as 5 kHz and provides
-dual-mode reception of both JT65 and JT9 signals. If your receiver can
-be configured with at least 4 kHz bandwidth in USB mode, you can set
-the dial frequency to one of the standard JT65 frequencies — for
-example, 14.076 MHz for the 20-meter band — and display the full JT65
-and JT9 sub-bands simultaneously on the waterfall. You can then make
-QSOs in both modes using nothing more than mouse clicks.
+WSPR (pronounced “whisper”) stands for Weak Signal Propagation
+Reporter.  The WSPR protocol was designed for probing potential
+propagation paths using low-power transmissions. WSPR messages
+normally carry the transmitting station’s callsign, grid locator, and
+transmitter power in dBm, and they can be decoded at signal-to-noise
+ratios as low as -28 dB in a 2500 Hz bandwidth.  WSPR users with
+internet access can automatically upload their reception reports to a
+central database called {wsprnet} that provides a mapping facility,
+archival storage, and many other features.
 
-Plans for future program development call for _WSJT-X_ and _WSJT_ to
-merge together. _WSJT-X_ will gradually acquire additional modes
-such as JT4 that are now supported in _WSJT_. The entire
-WSJT-related effort is an open-source project, released under the 
-{gnu_gpl} (GPL). If you have programming or
-documentation skills or would like to contribute to the project in
-other ways, please make your interests known to the development team.
-The project’s source-code repository can be found at {devsvn}, and
-most communication among the developers takes place on the email
-reflector {devmail}.  User-level questions and answers, and general
-communication among users is found on the {wsjt_yahoo_group} email

+_WSJT-X_ provides spectral displays for passbands up to 5 kHz,
+flexible rig control for nearly all modern radios used by amateurs,
+and a wide variety of special aids such as automatic Doppler control
+for EME QSOs.  The program runs equally well on Windows, Macintosh,
+and Linux systems, and installation packages are available for all
