Ken, Sounds like you found the source - part of the ground system. I would still recommend grounding the mic jack in any case - I do that routinely as part of any K2 that I have on the bench for upgrade.
For what it is worth, in the case of cables, I always look for the source of a cable break right at the point where the cord flexes most - normally right at the point where the 'strain relief' device ends - I have found this to be true especially on portable power tools, but it also occurs on mic and key cables too - cut 2 or 3 inches off the cable and re-connect everything and intermittent problems such as that vanish. 73, Don W3FPR > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Ken Bessler > Sent: Thursday, October 27, 2005 11:43 PM > To: Elecraft Main Group; [EMAIL PROTECTED] > Cc: Scott King - AH6KL Elecraft > Subject: RE: [Elecraft] Mic Problem? > > > Don, Scott - et all - Thanks for the help - after doing a full > reset & re- alignment then disassembling the radio to check for > GND @ mic socket pins 7&8 (ok), I re-assembled K2 #4913 and > focused on the mic again.
