Thanks Don. I put on 5.54.... The K3 is behaving differently.... No more jumping down 1MHz.
What it is doing now: there's still a relay clicking once in a while as I tune VFO A - this is within any given ham band. Now, while tuning VFO A, VFO B will jump frequency. Example: VFO A = 3.853, press A>B, tune A up frequency less than a kHz, B jumps, now A = 3.853 B = 3.994 Somewhat similar but stranger behavior on 40M VFO A = 7.274, press A>B, tune A up freq, B jumps a LOT, now A=7.275 B = 8.600 In the time it has taken to test and scribble the results, the rig has warmed up from 50F to 66F and it works fine No freq jumps, no relay clatter. OK, I went back to Firmware 5.52 & chilled the rig (53F). The jumping 1MHz down is back. Hmmm... Next step? I'm thing the FP flash memory has a problem with low temps.

That firmware improves the flash memory interface. I can't say for sure if it will fix that K3, but is worth a try. 73, Don W3FPR On 10/20/2016 10:16 AM, Bill Coleman wrote: > Have our club's K3/100, serial # 67xx.
