If it's like most 2-wire mics, you want a series resistor between V+ and the "hot" terminal of the mic. It serves as the load resistor for the output stage of the mic, and also limits current to that output stage to a safe value. If I knew nothing about the mic, a value on the order of 4.7K - 5.6K would be a good starting point. The mfr is giving you lower values. If you use NO resistor, the V+ shorts out the audio. 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
