[Elecraft] K3 Blank spots in RF gain contol

[Fred Atchley]

I just had an enlightening experience with the K3 RF gain control that may
help other K3 owners. As the RF gain control was rotated clockwise, a
significant drop in output occurred over a segment of 3 to 4 degrees at
about the 1 o'clock point. It seemed to me that the pot had a worn spot in
it (I'm an old analog type.)

However, when I contacted Elecraft Support, Gary recommended that I reload
FW and do an RF gain calibration. His suggestion worked! The RF gain now
works smoothly.

I hope this info is helpful. BTW, the Elecraft XG2 signal generator sure
made calibration easy. Thanks Elecraft Support.
