I have noticed this problem after assembling K3 of mine. Asked Lyle about it in Dayton. He recommended a few things which did not help in my case, the rising SSB power syndrome is still there. Looks like a slow RC-chain somewhere in the power control circuitry. It's just my assumption, which can be a wrong one.73, Vic US5WE/K1WEK3 #2907

My favorite workaround is to change mode to data FSK, switch to dummy load, then press PTT for a couple of seconds. Back to SSB and I have full talk power immediately. Can't comment on your other problem as I am still on 3.14. Knut - AB2TC Ignacy wrote: > > <snip> > > There is an old problem still present on 3.19.
