[Elecraft] K3 mic gain and bias settings

[James Sarte]

Hello Philippe,

Thanks for the reply.  It seems something has changed in the way the K3
handles mic bias and gain with the latest firmware releases.

I'm also wondering if there is a difference with the way mic gain is handled
between modes; i.e. SSB and FM.  I noticed that with FM, I have to crank in
a little more mic gain over SSB to get the same amount of ALC action. For
example, with 4.14, a mic gain setting of 15 is perfect for SSB while
approximately 20 is needed for FM operation.

As for the 4U1UN beacon, I'm still working on that issue with UN facilities
management.  Because of the renovations to the Secretariat, none of our
antennas are currently up and the club has no base of operations.  Hopefully
we'll be back up and running within the next 4 to 6 months.
