If you are seeing a fuzzy blob at the center of a crossed-ellipse display, it means that the (software) demodulator is tuned to some passband that contains noise and not the RTTY signal itself. I would check to make sure that the Mark/Space tone pair that you have selected in your software matches the tone pair that is selected in the K3 (while in AFSK A mode, hold PITCH button -- the K3 will display the Mark tone that is selected). 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
