Hi Bob,
MMVARI on does RTTY in AFSK. FSK is not supported.
Excerpt from the EMMVARI.TXT file (note last line):
* RTTY implemented in MMVARI are:
- 170Hz shift. It can be changed by macro command
<%TxShift...>, <%RxShift...>.
- Carrier frequency is the center frequency
- RTTY-L for LSB (default) and RTTY-U for USB (reverse)
- 5-bit BAUDOT S-BELL only
- UOS on the RX side is ON. It can be changed
by macro command <%UOS=ON/OFF/ONOFF>.
- UOS on the TX side is always ON.
- LTR diddle is always engaged. It can be changed
by macro command <%DIDDLE=BLK/LTR>.
- AFSK only (no FSK support).

I am wanting to use FSK for my RTTY mode and of course AFSK for PSK, ect.
Can someone tell me since I have the system set up with MMVARI and MMTTY how
I can know for sure that when I switch over to MMTTY
that it is sending FSK vs AFSK like MMVARI does?
I think I am sending AFSK from MMVARI and FSK from MMTTY but am not sure.
I do know that:
when sending with MMVARI and I adjust the MIC drive it makes a difference
on the ALC meter
but when using MMTTY the MIC drive makes no difference on the AFC only
adjusting the output power makes a difference.
