I did a simulation also this evening (after off line discussion with N1AL) and can confirm what Alan has said.
A 1 dB amplitude modulation only increases the keyclick noise floor by 0.5 dB 2 kHz away from the signal. It took a 6 dB difference in amplitude to raise the keyclicks 2 kHz away by 5 dB. 73 Chen, W7AY ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
