Peter, I have operated 6 meter CW and I have not had a report of chirp. I have heard some signals that sound a bit strange because of propagation anomalies. I have no way of knowing if this is your problem, but recently licensed hams have not heard the chirps that were common in the 50s and earlier so do not assume that the reports are really valid. Good luck! Willis 'Cookie' Cooke K5EWJ & Trustee N5BPS, USS Cavalla, USS Stewart

I had several of them and my K3 is back at Elecraft right now for service, but they are not able to reproduce the problem. I know there is a mod for the synthesizer board and that was made without solving the problem. No, it's not my power supply either - a big 50 amp Astron provides 13.77 volts key up and 13.74 volts key down. It's not RF because when I got the report I reduced power (external amp off) down to the point where the station could not copy me and the chirp was still there. The strange thing is I had a local listen to my signal and it was clean. At a later time, two reports (one from eastern MA the other from SC and I'm in central CT) said I had a chirp. In both cases I had been on 6 for a while. Is it frequency dependent? Is it heat dependent? Again, I would appreciate hearing from you if you have had reports of a chirp on 6 meters - what frequency were you on at the time? How long had you been operating (was the rig getting warm?) or any other observation that might help to pinpoint a way of duplicating the problem. Thanks!
