Re: On air tests of fldigi 0.941 beta
Glad to hear it works well on RH/FC-5 Tim. FeldHell and Throb are both on the drawing board. We could all use some help from the ionsphere. Seems like we have a great big rf sponge in the sky. Dave

Dave, I could not copy Olivia 16/500 on 40m just now, but could with your most recent gmfsk. The SNR reported from GMFSK was 32. Leigh/WA5ZNU

fldigi waterfall shape
There's something a little different about the fldigi waterfall, not just in the recent 0.941b. It seems less distinct when compared to the gmfsk waterfall and the Windows programs. Is there a

Re: On air tests of fldigi 0.941 beta
Dave, Have you seen the Visual CQ for PSK that I did? I think Patrick did a mode indicator for Olivia and I believe MixW has something similar, showing you the mode as an "image" in the power

Dave, Why don't you just make a modem library and share it between the two? I want to write another psk TCP/IP server anyway, as I did that in gmfsk because it had the cleanest modem code, as you
