AGC setting is probably the most often discovered internal problem with K2 audio.
I believe that there is still an internal gremlin yet to be exorcised, based upon reports that Ihave heard over the years. However, one additional problem that helped me was changing to a pair of headphones that better matched the internal impedence of the K2. I believe that this is 32 ohms. Good luck, Fran _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
