Chris,
On older K2s, there is no adjustment for AGC Threshold kike is found
with the newer ones which have a pot to set the AGC Threshold. R1 on the
control board - which is normally adjusted to produce 3.8 volts at CB U2
pin 5.
You can always set the CAL S LO menu parameter and CAL S HI to produce
no bars with no signal and an S-9 indication with an S9 signal. The
latter is normally set with the preamp turned on, but preamp off can
also be used.
We are in a sunspot low, so signals may not be as strong right now,
particularly on the bands above 30 meters.

Just took out the old K2 from storage and it works great, perhaps better than

Seems like the S-meter is insensitive. With the Preamp on the meter works
as expected, but otherwise no indication at all, even for signals with very
good S/N.
Is there an adjustment or parameter change to make the S-meter more
sensitive?
Thanks,
Chris
