Not a hand mic, but the mic on the Yamaha CM500 headset would work VERY well with a K2. The K2 is low on audio gain, and the CM500 is a pretty hot mic, so it will compensate. See http://audiosystemsgroup.com/HamInterfacing.pdf for guidance in connecting it. You will need to buy a mic plug, 1/8-in jack, and a small resistor of 4.7K-6.8K to make a simple adapter. You want to find a resistor small enough to fit in the mic connector. And you will need to consult the K2 schematic to see which pin is audio in and which pin is +8VDC. Wiring is simple. The mic connects between the audio input and the chassis (shell). The resistor goes between the V+ pin and the audio input. The pdf tells you a part number for the 1/8-in jack and where to buy it. 73, JimK9YC ______________________________________________________________ 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
