I'm curious -- what is the T-R setting on our K2 set to? If I set it to a high value -- say 150 (which I sometimes do when I'm using my non-QSK AL-80A amplifier), I don't get any thumps, but I wouldn't call it QSK by any means. If I set the T-R setting to something less than about 8, I can start to hear some anomalous stuff -- some minor thumps, and if I turn it down lower, I hear more. At settings below 2, you can even get some off-frequency receiver response. (ie you'll hear adjacent signals while keying, which stops the minute you stop keying) Bill Coleman, AA4LR, PP-ASEL Mail: [email protected] Web: http://boringhamradiopart.blogspot.com Quote: "Not within a thousand years will man ever fly!" -- Wilbur Wright, 1901 ______________________________________________________________ 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
