Pretty quiet, but not totally so. The answer depends on proximity of antennas and operating frequency. I just tested the 4A charger they supplied for my 20Ah battery and heard a very low level buzz on the 160M antenna 25 ft from my shack. A choke with 18 turns on a single #31 2.4-in diameter toroid killed it. > I appreciate any shared experience, Me too -- the state of the art is advanced when we do that in a thoughtful way. Thanks for the good question, Howie. I had asked it myself a few weeks ago, which is why I checked mine. 73, Jim K9YC ______________________________________________________________ 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 Message delivered to thelas...@gmail.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 Message delivered to arch...@mail-archive.com
