Re: [Elecraft] K3 Chirp on 6 Meters
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!

Re: [Elecraft] K3 Chirp on 6 Meters
Thanks Cookie - the two hams who reported the chirp are long-time CW operators who I've known for many years so I trust their feedback. In a separate case again the op reporting the chirp is a long-time CW op too. Could this be some anomaly of propagation? That would be very odd indeed. Thanks again!

Re: [Elecraft] K3 Chirp on 6 Meters
You didn't happen to be using CW in the SSB mode? That is the K3's ability to allow you to be on SSB, hear a CW signal and call him without changing mode. This practice is quite useful on 6M. 73 de Brian/K3KO On 8/12/2012 13:43, Peter Chamalian wrote: Thanks Cookie - the two hams who reported the chirp are long-time CW operators who I've known for many years so I trust their feedback.

The voltage read by the internal K3 meter says the voltage drops to 12.6 volts which I reported to the tech's at Elecraft. They did not think it significant. Also, the problem only has been reported on 6 meters. I'm a 98% Cw operator so if there was a hint of a chirp on the HF bands, it would have been brought to my attention by those I work regularly.

Re: [Elecraft] K3 Chirp on 6 Meters
Well here's the thing. 6m is most current hungry band and the one most likely to give you current warnings. I had the same comment for 6m cw chirp with mine. If you replace the APP connectors and use 10mm^2 cable in short to a close by solid 15v 30amp supply(I use a sw/mode), the chirp disappears. Your 3rd order TX IMD improves several to 10dB. The current warnings go away, The power level issues (starting too low then recovering) go away, despite all the TX gain calibrations you have tried. I only really liked my K3 after doing above.
