[Elecraft] K2 S-meter adjustment

[Don Wilhelm]

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.

73,
