Art, Mine has always closed the amplifier relay control line upon power up during the period after the power switch is pushed "on" and the display illuminates. The K3's red TX light is **not** on during that time. it does it any mode, and any VOX or PTT setting. Make sure yours doesn't do the same thing. I think this would mainly be a problem if someone power the amp and radio up at the same time, or powers the amp slightly before the radio is turned on. While my amps are immune to step-start damage, some systems can be damaged if the relay line is pulled low during the amplifier's power-up step-start sequence. This damage is a step-start design shortfall aggravated by an unusual power up behavior. It's more annoying to me, since it can't damage the amps I have, but it does make me look carefully at meters to be sure it isn't transmitting. Especially if I am reloading firmware and I have the amplifiers and antenna transfer systems all running. :-) 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
