Precis of problem: If a transmit frequency of <200 Hz is selected by holding
shift and clicking below 200 Hz, the transmit frequency will move no lower
than 200Hz. If a target station has already been selected, and his/her call
sign already double-clicked (transmit enabled), any attempt to move the
transmit frequency by holding shift and double clicking below 200Hz results
in loss of the recorded waterfall display (as well as moving the transmit
frequency no lower than 200 Hz). The waterfall remains functional, but
starts again as if the program was just opened. I've attached a
less-than-perfect video. I am very much enjoying the rapid decoding.
Thanks for the additional information. I still have not been able to
reproduce the behavior you describe.
It is intentional that the Tx audio frequency cannot be set lower than
200 Hz. This is because you might not be using Split=Rig or
Split=Fake It, and in that case the very low requested audio frequency
would be sent to your SSB transmitter. Most likely the audio frequency
would be outside your Tx filter's passband.
If I shift+click on the waterfall at a frequenct below 200 Hz, the Tx
freq is set to 200 Hz. If I decode a signal below 200 Hz and
double-click on the decoded text, the Tx freq is set to 200 Hz. I
haven't found anything that on my system "results in loss of the
recorded waterfall display".
If I have overlooked something important, or if your system behaves
different from mine, please give me an exact list of steps that will
result in loss of the waterfall display.
On a side note, I worked you a few months back. Excited by my brush with ham
royalty, I called over and over with an appropriate power of 30-40 watts.
Finally, I switched on the linear assuming the problem was my since-replaced
and long overdue for maintenance antenna. You gave me a -03dB report- I gave
you a -14 dB report. I was embarrassed at the realization I was using ten
times more power than necessary. I had meant to apologize for my violation
of the spirit of WSJT.
No problem at all! It's not always easy to choose appropriate Tx power;
QSB and QRM often determine how strong and how copyable a signal may be.
