[Elecraft] K3 mic gain and bias settings

[James Sarte]

Has anyone else noticed similar?  I still haven't gotten a definitive
answer, and am curious to see if others had experienced the same.

Also, I've noticed that FM always requires a bit more mic gain to achieve
the same level of ALC action as opposed to sideband.  Can anyone confirm?
