[Elecraft] K-1 trouble shooting

[Dan Coleman]

Yes, I can toggle AGC  on and off. No S-meter when on. I have also gone thru the troubleshooting section of the manual. All is within reasonable parameters. Q1 & Q2 test good. I have checked the path back to U1 pin 2 on the front panel. The S on Q1 stays at +1volt no matter if AGC is on or off. Voltage on cathode of D2 on RF board is .75 when AGC is on and zero when AGC is off. I have rechecked the component assembly of the front panel and it is correct.

Have you verified K1 MENU item AGC is toggled to ON?   AGC ON is required for the S-meter to function.  See last page of K1 manual for quick reference.

FWIW, almost NO  Elecraft model designation uses hyphens or dashes. :-)

I obtained a K-1 partially assembled. I completed assembly. All seems to work except there is no AGC nor S meter.I have measured voltages per the manual and checked components but I can't find problem. Any suggestions?Dan, W8KMX
