I have been busy setting up MMVARI together with N1MM to use in RTTY contests. I have not encountered any real problems, however I am a little confused when it comes to using the K3 in the AFSK A mode.
I am using this mode because it always has the RTTY LSB selected as default. The audio tones are fed into the K3 via the LINE IN. In the Data Mode section of the K3 Owners Manual it says:- AFSK A also uses Audio-shift transmit, but is optimized for RTTY. The VFO displays the RTTY Mark frequency, and LSB is "normal". I am not seeing the Mark frequency displayed on the VFO, but one which seems to represent the suppressed carrier. The displayed frequency is offset from the Mark frequency by about 1.3 kHz. This would correspond with the middle of the K3 filter passband. It would be nice to display the real (yes I know it's audio) Mark frequency as this seems to be a standard. a) Am I missing something in my K3 setup ? or b) The manual is wrong ? or c) Something else ? 73 Stewart G3RXQ ______________________________________________________________ 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
