Hi I got a Logitek headset / boom mic for the K2, figuring it would be less fatigue than my D-104 during the upcoming VHF contest. But no joy. E.g. no modulation at all even with ssba=3.
Looking at the output of the mic on scope set to 50 mV per division, nothing is visible. I figured maybe its a factory defect so I tried my son's Logitek desk mic on the scope and also see nothing. I even tried a 2.2K resistor hooked to the tip connection of the desk mic and biased it with 1.5V from a bench supply, thinking maybe its an electret. Still nothing. The D-104 with internal amp shows about 150 mV on peaks. And a Radio Shack electret element with a2.2K resistor and 1.5V bias gives even more. So what is it about Logitek mic's (or is it computer headsets in general)? Should I return it? The set is light and comfortable and I'd like to keep it if it can be made to play. TIA. 73, Lenny W2BVH K2 sn 1520 ______________________________________________________________ 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
