Several of the guys in our contest club have bought these headsets and fired them up with their K3s. One of them, W6XU, brought one to our meeting last night, and I tried it on. It is quite comfortable, and well built. The headphones are of the "big closed" type that provide some isolation from noise in the shack. They are NOT active, noise-cancelling type. The mic is a cardioid electret. Another of the guys, K6TD, had me listen to his on the air. It sounded very good with no tweaking of the K3, and with tweaking, produced very competitive audio. The tweaking consisted of using maximum cut on the three lowest filters, 6dB boost at 2.4 kHz, and 10 dB boost at 3.2 kHz. I also had him kick in about 10dB of processing. This eq is consistent with most mics designed for SSB communications use (like the Shure and Heil products). The difference is that this headset sells for only $45 online at Sam Ash with free shipping, a bit more at other vendors. For those who don't know, Yamaha is a well respected audio company. 73, Jim Brown K9YC ______________________________________________________________ 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
