[Elecraft] Audio levels in K2

[Francis Belliveau]

AGC setting is probably the most often discovered internal problem with K2
audio.

I believe that there is still an internal gremlin yet to be exorcised, based
upon reports that Ihave heard over the years.

However, one additional problem that helped me was changing to a pair of
headphones that better matched the internal impedence of the K2.  I believe
that this is 32 ohms.

Good luck,
Fran
