The two antennas are a zs6bkw and a OCF dipole. Both are up about 32 feet and the ends are 12 foot off the ground. The coax is LMR400 and is new. The antennas are located on the opposite side of the house from the shack. The amp is powered by a 240 volt plug and the power supply is 110 volt. This happens in all modes, CW, Voice, Psk31. It happens on all bands. It only happens when the power is increased to 300 watts or higher. My station ran great for several months 6 to 12 months. Then all of a sudden this problem showed up.
I will start filtering everything tomorrow to see if that helps. Thanks for the replies I will try your suggestions Gerald ----- KC6CNN - Gerald K2 # 5486 K3 # 6254 KX3 # 757 -- View this message in context: http://elecraft.365791.n2.nabble.com/kinda-like-other-post-K3-turns-off-tp7580359p7580362.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
