Take it you have the original mic aswell as power mic and is this in all modes = am/fm/ssb George ?
If only on FM then it could be the variable resistor that is marked usually FM Dev,as this is set too low ?
Does the mic need the wire on pin 4 disconnected ?

Plenty are talking worldwide on 27.555 usb,
Some are too far up their own @rse to admit it,
Many happen to know otherwise dx-ing test free,
Showing a complete lack of respect for the law.

I'm having similar problem, and wondering if there is an interal adjustment ? Or perhaps something could be removed for more AM audio in my case?

Low means how much percentage measured with the scope?

No it means compared to majority of my other radios I use hooked up using as a base setup through my beam with low SWR basically. I'm not talking a BIG problem here but curious if there is a trimmer inside the unit for mic gain too. Don't know if they are marked inside either. Seems someone would know for sure without having to pop the cover myself. I know the mic gain on mine is in the menu for the 1st option having version 6 here!

Thank you CC, much appriciated. Yeah not wanting it on default for AM, typically a bit LOW. AM here in USA tends to get a bit rough sometimes and one needs to be able to punch through with good solid clear audio. I don't like to over drive the circuit either! Wonders if clockwise is up or down, but it'll be easy enough to tell.
