Correction - on FM, I have to increase mic gain settings by 200%, not 50% as
I had written.

For example, what might sound fine using a gain setting of 5 on SSB will not
produce full modulation on FM at the same setting.  I have to turn gain up
to 15 for similar results.

I'm very curious about this now.  Can anyone test their K3 and reply?

Tnx,
James K2QI
