In case others are having a brain freeze on how to extend the frequency range up or down on JT9-10 Ill offer these answers from Markus and Stefan as I got stuck in an endless loop last night.
Question - Markus/Stefan -
How do you get up to 1400Hz on rx jt9-10on rx when the indicated rx is just 1000-1100Hz ??
Answer -
- increase the "FFT Bins / Pixel" at the bottom left of the spectrogram (e.g. to 8), so that it zooms out and you can click on the appropriate audio freq,
-or close the program, edit the QSOfreq entry in wsjtx.ini, and restart.
or - by using 136.4 kHz "dial" and then 1020 Hz audio...
Cheers
