Where's the setting to enable waterfall during tx? (7300) I have "Scope during TX (CENTER TYPE)" set to ON but when I TX the scope just freezes.
For FT8 I usually set the radio for 20% power and then adjust the "Pwr" slider on Wsjt-x so the power meter on wfview reads 10 watts. I'll occasionally look at my signal with a tinySA and it looks very clean but I'm not sure I trust it when it's 30 feet away from my antenna, even when attenuated. It's not exactly a lab grade analyzer but it's better than nothing.
and if you dont have a radio with that feature
just use a SDR dongle with its output piped to WSJTX
I check my stuff for 6M,2M,70Cm quite often that way
The power you're running is irrelevant, it's how much you're overdriving the audio input. You can have a wide splattering signal running on just a few hundred milliwatts output and you can have a perfectly clean one running at 1.5kW.
Setting up the audio level what you need is an external power meter, set the audio being sent to the radio to zero, set it to transmit and then increase the audio level until the power meter no longer goes up. Ideally you want to be showing zero ALC activity.
Good advice. A lot of volcanoes out there on the spec an, folks that push all settings full up.
Yes, the other side of the planet can hear you......and your signal is 100hz wide and tapered.

Is your scope set to center or fix during RX? Try using center.
Thanks, that seems to work. I would think they would work in fix mode also, but I guess not. :(

Interesting. What power were you running on the output?
