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. Dan, W8KMX

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. :-) Mike / KK5F -----Original Message----- From: w8kmx <w8...@bellsouth.net> Sent: Mar 5, 2023 5:00 PM 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 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
