I had the same problem when using my K2/100 for RTTY. I had the headphones bridged across the audio output feeding the sound card and I could hear the polling. It sounded like a low pitched "rush ... rush ... rush ..." sort of similar to the ET signal in the movie "Contact" -- only not in prime numbers :-) It was louder when I powered the laptop from the mains, almost disappeared on the battery. It did not show up on the transmitted signal. I switched to the K3 for RTTY, and don't have the problem anymore. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ 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
