all, thanks to Craig, N6RSX, who referred me to Mastercommunications, which make a series of soundcards. https://www.masterscommunications.com/
I got the DRA-100RJ45 model.
For this model it is compatible with the tigertronics signalink with regard to cables and wiring. I am using the DRA with my Yaesu FT847, soundmodem software.
After some change in software settings that Keven helped me thru, it is working fine. and am evaluating how it hears vs the signalink. So far its early days, but doing very well on MO-112 at lower elevations.
One thing, with this DRA unit I can Tx 9600 bd rate on the FT847 with radio menu setting on 9600 or 1200.
This model also has hardware pitt, with option of VOX. Other options are described on the website. Just thought some of you may want to see other choices out there.
and the customer service is outstanding!
