Weird modulation

Zacharias Liangas

Totally off topic discussion with a funy  transmission !!

Just listening to a friend pirate . here in the screenshots you will see his transmission problem : Poor microphone modulation win the LSB part , good modulation for the incoming calls and a carrier wandering depending on the mod index. There is another carrier on the frequency.

I include also the 25 minute IQ recording screenshot to show on how his carrier wanders!

His program is only phone ins with general discussions  and only after 2100 to 00!!
