<<Sometimes I'll walk way from my tube amp and leave it in standby mode and turn off my K3. Well, a few weeks ago I forgot to put it in standby and I came back to the radio from working on my antenna outside and the swr was changed which was set on the tuner. When I turned on my K3, I damaged the amp. I forgot that when you first turn on the K3 that it transmits a signal (the clicking sounds when it fires up) for about a second or so and damaged my amp because of a high swr. Never again I will leave the amp without putting it in standby. Very costly mistake. The amp was set at 1100 watts. To make a long story short, I had the tubes replaced along with other things in the amp and power supply. I could have bought that new P3 for the amount of money that I spent for my error. Now that new P3 will be on the back burner for a while. >>
I do not believe the K3 actually transmits RF, although it does close the amplifier relay line connection RF never appears. Mine activates the amp briefly, but does not actually transmit RF. You must have had something else going on. What type of amplifier do you have? 73 Tom ______________________________________________________________ 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
