Hi I intend to buy a (1K$) noise canceling Headset to suppress the very disturbing FAN noise by my KPA 500 in QRQ > 30/40 Wpm CW Mode. Changing of FAN + external Fans not successful.
Will this work with the K3S. Bose says EMI /EMC should be ok for HF. I understand DC Bias 8V is no problem. How about the Stereo 320 Ohm Earphone impedance and the K3S recommended 16 Ohm min ? How should the electret mike be configured Bias through 220 to 2200 Ohm? Any experience here? tnx vy 73 de Andy HB9CVQ ______________________________________________________________ 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]
