I have been using the CM-500 for 3 days already,always using 1KW from my AL-80B on 40M with a dipole and on 20M with an AV3 vertical antenna and so far I don't have any RFI anywhere,they are RF safe for me. AD4C

I have one of the old ones which pick up the transmitted rf and really annoying. I have always used the Heil headsets and elements. My voice seems to work well with them. I always get excellent reports. I would agree that their prices are high.

I've never owned a Heil headset because I think they are wildly overpriced and many sound bad. I've used Heil headsets at the N6RO contest station when others brought them. I found them moderately comfortable, but the headphones in the active ones (noise cancelling) picked up transmitted RF from antennas that were 100-200 ft from the shack. I bought two CM500s as part of a group purchase by our local contest club two months ago (Altogether, I think we bought about two dozen), and I have used one extensively in a half dozen contests. I'm a serious contester, so that often means 24 hours or more in a weekend. I find them to be as comfortable as my Sony MDR7506s, they sound nearly as good, and the mic gives me VERY competitve, good sounding audio. I've listened to other club members using these headset mics, and they sound much better than most of the Heils I've heard. 73, Jim Brown 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 ______________________________________________________________ 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 ______________________________________________________________ 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
