This sentence: When SHIFT is set to for example 0.45; the problem happens on all frequencies from 3.577.11 - 3.577.19
Should read: When SHIFT is set to for example 0.45; the problem happens on all frequencies from 3.577.00 - 3.577.07 My apologies Thanks for the responses. It was also suggested that I do the KSYN mod and then the VCO CAL. I did both and still have the problem. But this is a very localized problem and I am now able to reproduce it whenever I like. I'm actually wondering if this is a bug... so if someone else could please do a test to see if you're also able to hear the chirp I would appreciate it. It only happens for me with a frequency from 3.577.11 to 3.577.19. Any other frequency works fine - when SHIFT is centered... When SHIFT is set to for example 0.45; the problem happens on all frequencies from 3.577.11 - 3.577.19 Power setting or filter WIDTH does not make any difference. I am using a dummy load when testing. You do of course have to listen to yourself on a second receiver if you try this: 1) Set K3 to 80M CW 3.577.15 2) Make sure the SHIFT control is centered at 0.60 and try keying. When I QSY to to 3.577.00 the problem goes away but comes back on all frequencies between 3.577.00 and 3.577.07 when the SHIFT control is set to .045. I can change the frequency slightly the other direction too and reproduce the problem by changing the SHIFT control. The problem is absolutely consistent but the SHIFT control needs to be exact at the 'problem FC' to cause the problem. If you can't reproduce it with these exact settings, maybe try to vary the sift control a few notches. 73, Are - LB3SA wayne burdick wrote: > > Check in with k3support.
