""I find the Astron SS-30 is generating all sorts of noise. ""
For the past year, I have used an Astron RS-35A (linear = heavy) with excellent electrical results. Just yesterday, I removed the power transformer mounting screws and added rubber equipment feet as isolators and remounted the transformer. This eliminated the annoying audible (not electrical) hum that I had been putting up with all this time. 73, John W2XS -- View this message in context: http://n2.nabble.com/K3%3A-N1MM-for-Field-Day-tp2864853p2865329.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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
