Re: [wsjt-devel] Superfox Waveform

Here's information on the "750 Hz tone" received at this QTH. I am listing K8R's frequency as reported on my screen. Please explain. The tone frequency reported matched the left edge of the modulated waveforms on the waterfall when I could see tones.* July 11 RX 21091.0 830 Hz successful

Re: [wsjt-devel] SF rc6 TX signal "fuzz"

If you turn down the gain so it looks "cleaner" then you won't see it when it's weak. So what if it looks a little noisy?  That's what the FFT actually looks like since it's doing a hard shift between frequencies. Mike W9MDB On Tuesday, July 23, 2024 at 11:34:00 AM CDT, Andy Durbin via ws

"Turn your waterfall gain down (top left slider) and it will clean it up mostly. I have a +20 dB SNR file and it is awful looking until you turn the gain of the waterfall down." Thanks for the tip. I have viewed many much stronger signals using the same waterfall setting and have not seen simil

Re: [wsjt-devel] SF rc6 TX signal "fuzz"

Andy, Turn your waterfall gain down (top left slider) and it will clean it up mostly. I have a +20 dB SNR file and it is awful looking until you turn the gain of the waterfall down. This has nothing to do with decoding, simply a display issue of limited dynamic range. 73, N0AN Hasan On Mon, Ju
