problem with DAX and MMTTY

I have MMTTY 1.66G working with SSDR 1.3.8 when using DAX channel 1 but cannot get MMTTY to work with any of the other DAX channels. I put RIT and XIT at 1415 Hz when operating RTTY so the Mark frequency is correct. When calling DX stations operating split I use XIT.

Today, FT4TA is on 28,080 listening up above 28,100 so I cannot call him as XIT is limited to 9,999 Hz (from what I can tell).

For split operation, I can't get MMTTY to use Slice B for TX with DAX channel 2 while I listen on Slice A DAX channel 1.

DAX audio TX 2 does show up in MMTTY Setup however selecting it doesn't seem to do anything.

Note I can only seem to rx in MMTTY via DAX channel 1. All the DAX channels show up in MMTTY setup but only DAX Audio RX 1 seems to work.

Any ideas here? I want to work FT4TA on RTTY!

    Have you tried RIT one way and XIT the other for a wider split?

    That's a good idea!

    I was able to work FT4FA on 10m RTTY eventually when the split came down under 10 kHz
