Hi folks, so sorry to bother you over here. I realized strange behavior of my trusty K3 (#778 fully upgraded, loaded, latest synths installed) When I tried to exciting KPA500 amp I suffered with strange overshoots during first dots.
Symptoms: - up to 12W from K3 all is ok, over 13W the full scale deflection on KPA500 appears on first dots - after 1-2 dots power drops back to expected power based on exciting power level - the overshoot appears again after band changing or switching between OPER/STBY - 160m-30m are heavily affected, 20m-10m behaves better and it can be driven up to 18W but overshoot appears too (just slightly to about 600W on LED scale) Conditions: I realized that behavior into antennas with SWR all below 1:1.4 > no SWR protection activated at all. The same issue appears into dummy load. I will be happy for any kind of ideas or hints where to start...:( Many thanks in advance. 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com -- What could be easier..? ¯∖_(ツ)_/¯ ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
