- Notice the [green]*GREEN* and [red]*RED* markers on the waterfall
|
|
|
|
|
frequency scale. Decoding takes place at the end of a receive
|
|
|
|
|
sequence and is organized in two stages. The first decodes take place
|
|
|
|
|
at the selected Rx frequency, indicated by the green marker. Results
|
|
|
|
|
appear in both the left (“Band Activity”) and right (“Rx Frequency”)
|
|
|
|
|
text windows on the main screen. The decoder then finds and decodes
|
|
|
|
|
all signals in the selected mode(s) and the displayed frequency range.
|
|
|
|
|
The red marker indicates your Tx frequency.

|
TIP: At least eight JT9 signals are present in the example file; all
|
2014-01-23 20:12:12 +00:00
|
|
|
but one of them are decodable. When this file was recorded KF4RWA was
|
|
|
|
|
finishing a QSO with K1JT. Since the green marker was placed at his
|
|
|
|
|
audio frequency, 1224 Hz, his message “K1JT KF4RWA 73” appears in both
|
|
|
|
|
decoded text windows. The “Band Activity” window shows this message
|
|
|
|
|
as well as all the other decodes at nearby frequencies. The CQ lines
|
|
|
|
|
are highlighted in [green]*GREEN*, and lines containing “My Call”, in
|
|
|
|
|
this case K1JT, are highlighted in [red]*RED*.
|
|
|
|
|
|
|
|
|
|
- For this step and the next, you may want to pretend you are K1JT by
|
|
|
|
|
entering that call temporarily as “My Call” on the <<X11,Configuration
|
|
|
|
|
Screen>>. Your results should then be identical to those shown in the
|
|
|
|
|
<<X12,figure above>>.
