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
Dear OM's,
thank you for reading this.
Yesterday I finished the control board, the front panel board and
the first stage of the RF-board - ready for the alignment, part 1.
Yesterday I did all the steps from the manual, alignment part 1
sucessfully - even the S-Meter alignment and

The most likely cause of bargraph LEDs not lighting is an intermittent
soldering connection, and since some LEDs light while others do not, the
problem is most likely found on the Front Panel board.
I would suggest you re-flow the soldering of Front Panel U4, RP2, R12,
and the

Question: Should this have said RF Gain instead of VFO knob ?

No this is the VFO knob... turning the VFO knob when calibrate the S HI
and S Lo paramater should be use to adjust the bar led display for
proper receivng indication. If turning the VFO knob does nothing, you
should probably have something wrong...

Gary,
You missed one prior step - enter the menu and edit 'CAL S Hi' first, and
then the VFO knob should work as described - you should see a display like
'S HI 018' (the number will change as you rotate the VFO knob).

I should have done as in the first stepafter entering the menu again and
selecting CAL S HI, I should have done:
Hold EDIT a second time to activate it. That sentence wasn't in the manual
and I'm just learning the procedures with this rig. Everything checked out
OK. On to Assembly, Part II.

I'm not sure whether this is a problem or not but after performing the S-meter
alignment on p. 47 of the K2 assembly manaual, the tenth bargraph LED stays
lit. It is lit whenever I turn on the rig. The AGC threshold is 3.80 Vdc at U2
pin5. I have completed
