Nor have I in my one ham shack. In fact, the only time I've heard the fans come on is when I shut the amp off at the front panel *and* have my hearing aids back in. YMMV, but my K3 and KPA500 appear to be silent devices. 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org ______________________________________________________________ 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
