That’s a snazzy little design Nomadradio. Thanks for the link. I do it without the nice little circuit board. Well done.

There is a post on accessing the service menu to adjust the audio limits. This is almost identical to the anytone 5555. I will try to find the post and link it here when I get a chance.

One more note. The PLL Alignment is spot on. Yes the PLL Alignment is different than most I've done. It is complex because of the 100 Hz resolution.

With no modulation there is a hum in the carrier. I can hear this on a radio without an antenna. Also I can see about 500 mv of that same hum on the scope with no modulation. I think if I can find the source of that hum, I will solve the problem. Also note that side band is perfect. No spurs and...

if i showed a video you would see that there is modulation components in the spurs.

Here is the Spectrum and Scope readings. I'm just getting back into this one. Thanks for your input. This is the result of even a slight amount of mic gain.
