Looking for tips on using MMTTY with SSDR
Looking for tips on using MMTTY with SSDR
I have got MMTTY working with SSDR and am keying via SmartCAT.
A few issues:
(1) I am not hearing my tx audio, MON button is selected (using DAX to connect to MMTTY rx and tx)
(2) For lack of a RTTY mode in SSDR I am using DIGL. I changed the mark tone to 1415 Hz in MMTTY so that the rx signal is centered in the DIGL passband (did I do the math right?). Will my 'VFO frequency" still be correct when spotting stations?

For the VFO to be correct for spotting/click tuning, you need to enable and set RIT and XIT offset equal to your AFSK Mark frequency.
AL, K0VM
Also, I just discovered that setting MMTTY Mark to 1415 Hz only changes the received frequency and results in me transmitting on the wrong freq.

Frustrating! Does anyone have a "RTTY on SSDR For Dummies" document I can read? I want to use MMTTY and report the correct frequency on packet spots.

Use Fldigi, hi hi.
Tnx for info
Good luck.

easy to do
Just go into Device Manager
Select Port 4
Go to Advanced
Change Port Number 4 to Port 9
Save
reboot the computer
it should now show as Port 9
