If this is correct, and RMS Express tunes to the correct frequency in USB mode but not in DATA A mode, then there may be an error in RMS Express. DATA A is exactly the same as USB except for disabling compression and EQ and the default choice of input audio path (line in instead of microphone). In particular, the frequency display in DATA A and USB is the same. A setup that works in USB should work in DATA A without changes. What I suspect might be happening is that RMS Express might be programmed to handle DATA A as if it were a USB version of AFSK A. In AFSK A, the K3's dial displays the RTTY mark frequency, whereas in DATA A the dial displays the suppressed carrier frequency. If the RMS Express programmers assumed that in DATA A the radio's indicated frequency was the center of the bandpass instead of the suppressed carrier frequency, they would program it to tune the radio 1.5 kHz too high in DATA A. 73, Rich VE3KI ______________________________________________________________ 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
