CAT command issue with new RTTY mode ?

I noticed that when my logging program sends the following CAT command to my 6300 the slice A frequency changes correctly but the mode shifts to DIGL instead of to the new RTTY mode:

<FR0;FA00021089100;MD6>

I believe MD6 is the correct CAT command for RTTY mode.  Has anyone else seen this  CAT command issue with the new RTTY mode ?

That is the wrong mode command syntax.  The value for RTTY is 30.  This is covered in the SmartSDR CAT User Guide.

Actually it seems to be missing from the CAT user guide. If you look up the MD command the highest number for P1 is 9 ( see below ). That said, I assume you are telling me if I send the radio a CAT command with ;MD30 in it will switch to the RTTY DSP mode ?

From CAT User guide :

MD Sets or reads the DSP mode

MD

Notes

P1 = 1 LSB

2 USB

3 CW

4 FM

5 AM

6 DIGL

9 DIGU

Neal - we have strict adherence to the Kenwood command set for compatibility reasons.  the MD command does not have an equivalent "RTTY" mode.  Reverse digital is DIGL.  The command you need is the ZZMDxx: command.  ZZMD30;

Sorry, I did not mention this earlier.

You must have a special version of 1.5 CAT doc :)  I am looking at Doc ver 1.16 dated 9/10/2015 SSDR CAT Ver 1.5.0  .   The MD command is documented  on page 39 of 45 and I don't see P1 = 30 in the list. Probably would be a good idea for Flex to add it

No just the one available on the downloads page.  Either way good to see you got what you needed.
