Is it possible to detect audio clipping on a sideband signal?
I've just recently obtained a bluetooth headset and adaptor. The bluetooth adaptor connects to my Yaesu FTDX3000. I've found that normal mic gains are far too high, so I've had to wind the mic gain back to about 7 to allow for this. Problem is, how do I know when the audio is clipping? Obviously, I want to get full modulation without clipping. I am feeding into a dummy load and monitoring on a RTL-SDR.com device, but it's hard to see if there is clipping or not.
See attachment. There seems to be lot's of harmonics. I've wound back the mic gain and there is less harmonics, but how do I know if I'm modulating 100%?
