If you use an electret with no bias you have no audio. What happens if you use a dynamic mic with bias on such as the HC4/HC5 element in the subject line?
John KK9A From: Don Wilhelm Tue Apr 18 07:35:33 EDT 2017 "Rule of thumb" - if the microphone produces any audio at all with no bias, it should be run with no bias - it is a dynamic type. Electret elements will not produce any audio at all unless bias is turned on. 73, Don W3FPR ______________________________________________________________ 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 Message delivered to [email protected]
