Hello, a friend of mine gave me an old microphone from Philips (serial no. : C944685 ; part no. : 3513 505 00692) which I want to use with my K2 transceiver. The friend said that it should be an electret microphone, so it will need a bias voltage (he said 12V, but I found in the KSB2 manual that some mic's work well with only 5V). It is also written that some mic's need a bias resistor between AF and 5V. Is there someone who has a manual to the described mic or an idea how I can find out how to connect the mic.
Thx for your help 77 Benny DL8NWO http://elecraft.365791.n2.nabble.com/file/n6954471/IMAG0168.jpg -- View this message in context: http://elecraft.365791.n2.nabble.com/Bias-Resistor-for-microphone-tp6954471p6954471.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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
