I have fairly new K3 & KPA500. They both are running the latest software. When on CW I typically call a station with my RX filter set at 2.8kHz. If there is an increase in noise level, or other adjacent signals I will switch receive BW progressively from 2.8kHz to 1.8 then 400Hz. When I then resume transmitting I notice that I will see what appears to be a power spike on the wattmeter on the KPA500 from 500 to 700 watts for one or two dits, then drop back down to 500 watts. The fault light does not flicker or come on when this happens. This never happens when switching to 250Hz. It consistently happens when going from 2.8 to 1.8 and from 1.8 to 400. All filters are from Elecraft and are 8 pole.
Have others seen this and is it normal? Is there a problem with this? Is it an actual spike in power from the K3 resulting in a spike from the amplifier? 73 Peter VE3SO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
