Pete,
If you turn the RF Gain down gradually, do you get a progression of LEDs
to light one at a time?
If so turn the RF Gain fully clockwise and then adjust Control Board R1
to obtain 6 volts at CB U2 pin 5.
After that, adjust CAL S Low and CAL S Hi.
If your K2 SN is lower than 3000, R1 is FIXED RESISTOR.

Hello,
My K2, which I purchased mostly built, had some issues which I appear to have
repaired.
However in starting the alignments with AGC and S-Meter, I find an issue which
just began where I cannot get a single barograph segment to light.
In DOT bargraph mode in S CAL LO I cannot get just 1 segment to light. It jumps
from nothing to 4 segments.
This just began as I have adjusted the S meter previously.
Does anyone have an idea what is causing this? I’d appreciate any suggestions.
BTW - Voltage and Current draws are correct. 13.8V and 220ma in Receive mode.
