Hi Don, many thanks for kind help and reply. Unfortunately I don't think its DAC sampling issue...
I checked it happends on any power level (not depending to the power level setting) and it happends in my case only on 40m (band 1). Also I realized that the power variation is sometime 0.5W and sometime 2W... and even more sometime its jumping up and sometime jumping down. What is most strange is that when I am not touching the band switching button it seems to be stable > even on lower power (instead of pre-set power) it does not changes. I checked our second K1 which is for long time used by my daddy and I did not realized anything like that on this radio. I will try to verify all parts around the Q5 as you suggested. I will be happy for any other kind of hint or tips... ----- 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com MeWe: https://bit.ly/2HGPoDx MeWe: https://bit.ly/2FmwvDt -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
