The most likely causes are phase noise produced by inferior transceiver designs, and distortion products in transmitters and power amps. > Is their ALC or compression too high? That can also be a cause, and also overdriving audio. These products would vary in strength with modulation, and most prominent on audio peaks. > Is the frequency response of their microphone too wide? No -- transmitted bandwidth is limited by the transmitting filters in the transceiver. Virtually all mics have response from at least 50 Hz to at least 10 kHz, although the degree of uniformity can vary widely from one mic to another. 73, Jim K9YC ______________________________________________________________ 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
