RTTY+Freq+offset+ n1mm+

Need to get N1MM+ frequency and Flex frequency to display the same in RTTY -- need SSDR to display Mark frequency. I've gotten RTTY to work fine with MMTTY, 2-tone and N1MM+, DAX and SmartCAT except I cannot get the N1MM+ frequnncy and the FLEX dispaly (and click tune) frequency to be the same. N1MM+ displays the Mark frequency IF its placed on the bandmap from the outside, while SSDR displays the carrier frequency. If I put the station on the bandmap, it is there on the FLEX carrier frequency. Someplace I need to set an offset, but I can't figure out where. MMTTY allows one to display an offset frequency but that doesn't help SSDR or N1MM+ don't pick it up.

Mike,
  Until Flex provides a solution, I set  and enable the SSDR RIT/XIT to the AFSK mark frequency tone ( for me that's 2125hz )  then logging programs, spots and SSDR will all show the same frequency.

 An additional consideration is that, by default, the SSDR files are centered on 1500 hz so you may wish to use 1415hz (DIGL) your mark frequency.

Thanks, Al. I've been using 1415 as my mark frequency. Your answer explains the RIT/XIT and second slice, split operation questions I've been seeing. I see how that puts internet spots on the correct frequency, but what about spots I generate? Wouldn't they show up incorrectly now? I use spotting mainly so I can skip over stations I have worked so I don't have to wait for an ID. Not a big problem on RTTY, as most ops ID every QSO.  --Mike, WV2ZOW
