Just received a KPA 500 and KAT 500 yesterday. Using them with my Icom 7300. I know the manual says to expect some hum from the KPA 500 but I believe mine is more than a hum. When I send CW I don't need to monitor the radio side tone. I just have to listen to the amp. :-) Anyone else experience this?
My HV voltage is 75 at idle. I am using 120V power. When I key down it drops to around 58. Manual says 60+ is best. Don't know if this has anything to do with the hum? I have not contacted Elecraft yet. I wanted to hear what folks say first. 73, Tom KQ5S ______________________________________________________________ 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 Message delivered to [email protected]
