Thank you for the additional details. The commands you wrote about in this thread should give you what you want. Have you had a chance to try them out yet to confirm? I haven't tried myself, just read the programmer's ref guide (E19) and drew it out on a piece of paper so I could see the bandwidths and how they shift. I always struggle with which way to shift. Even wsjtx split mode gets me second guessing the direction of the shift. Luckily the app knows what to do :-).
Is your motivation for reducing the noise above 2.5Khz due to unwanted AGC action from these strong signals? We can take this part of the conversation off-list if you'd like. regards, Brian VE3IBW On Sun, Apr 28, 2019 at 11:58 AM John Newgas <g7...@newgas.net> wrote: > Bottom end of the audio passband at 500 because all heartbeats etc. should > normally be in 500-1000Hz range.
