Flex 6000 & MMTTY Decode Setup ??

  • 1
  • Question
  • Updated 9 months ago
Relatively new owner of a 6600 and user of SSDR. Have yet to attempt RTTY, so just tried to play a bit in OKDXRTTY contest. Have watched a You Tube video on setting up SSDR & N1MM for RTTY. So think I have right DAX settings and CAT/PTT ports set up. I am in RTTY mode on the 6600. I am transmitting fine. But on the RX side I apparently have big issue. So I see the these beautiful RTTY sigs in panadpater but when I click on them, I am not seeing the sig in the XY or FFT scopes in MMTTY or 2Tone decoders. If I change the mode to DIGU- I now see the sigs but if I tune on the peaks - sigs are not decoding. So what do I have wrong in my setup?? Any help would be much appreciated.

I just got my newly acquired 6500 running on RTTY this morning and made a few contacts in the OK contest.  I found it easiest to expand the panadapter trace until the RTTY signal peaks for one signal were a bit less than 1/4 inch apart.  Then in RTTY mode, the tuning line will appear as two vertical lines instead of one, separated by 170 hz.  If you then tune the signal so the two vertical lines are on the peaks of a signal, you'll be right on the button.  The crossed elipses display should show a perfect image at that point.  I set the step on my 6500 to 5 (usually use 10) for ease in tuning the RTTY signals.

Have you set the MMTTY sound card audio input to DAX audio RX 1 or any one of the three other DAX inputs?  Have selected the corresponding DAX  number in the receive flag?

I have to continually check the Mark and space tone settings on teh MMTTY setup screen off of the WW RTTY tab. I can click on the Set Default(demodulator) button. I havent figured out what is messing the valuses up but it is a frequent thing.

I had the same problem a couple of years ago with Winwarbler.  The problem for me was a result of how I had the RTTY offsets configured in Winwarbler Config.  I can't recall the exact problem, but unless you specify them a certain way, you'll have that problem.  Here's how mine are specified:

Last radio was a K3 and I always used 915/170.  What are you using?

Problem solved by setting the Mark space to 2125, my "old' settings weren't applicable. Both 2Tone and MMTTY doing just fine now. Signals present in scopes and decoding is fine.

Tnx
