Mike,
That means you have some problem with U2 or Q12. Something not
soldered? D1 not installed correctly?
Once you make those checks, if you find nothing incorrect, I can make
some voltage measurements for you.to compare.
What value did you get for the CAL S LO parameter? Something in the 175
to 190 range is normal. CAL S HI will normally be in the 18 to 25 range.
73,

On page 48 of the K2 manual the S-meter alignment is done. I was able to
get the Cal S low done just fine. When I then moved on to the Cal S HI (
with the RF gain fully counter clockwise) I was not able go get any
segments of the S meter to light up. I adjusted the VFO full circle and
not one segment of the S meter would light up. The AGC voltage was
adjust to 3.80 volts DC without any problem. Also I read on the list of a
similar problem and Don suggested to check RP6 pin's 9 and 10 and U6
pin 3 (all on the control board) I reheated and soldered these, actually
all the pins on U6 and RP6 and this did not solve the problem. Just
wondering what the next step would be?MikeVE3WDM
