[Elecraft] S-meter alignment

[Evert Bakker]

Hi all,

May be I'm to critical but lets try once more. After finishing the AGC 
Threshold setting, the next alignment is the S-meter. When completing 
the last CAL-S-HI step, and setting the RF Gain potentiometer back to 
full CCW, only led nr. 9 lits and not nr 10. Trying to correct this I 
pressed the menu button and immediately led nr 9 goes off and led nr. 8 
lits (Huh??). Rotating the VFO knob to search for the CAL mode, led nr 8 
switched off and led nr 10 comes on again.



To be short, I tried many times to get the required result but there 
seems to be an instability somewhere in the circuit. I checked the 
supply voltage (13.8V) and the two regulators on the Control Board to 
see if they were producing accesive noise at the outputs, but they 
looked ok (less than 2 mV noise and limited by the scoop, Tek 2465B).

Has anybody out there a slightest idea what I'm doing wrong (or even worse)?
