[TenTec] Orion and rtty

[Art <k6xt@arrl.net>]

There is limited advice in my Orion manual, and the rtty pdf isn't all 
that clear. I want to use true fsk.
Would I be correct in assuming the rtty in acc1 is open equals mark, 
grounded equals space? That is to say, will my Writelog interface, the 
one in the WL helpfile that I built, work just fine on the Orion? Is the 
offset an automatic 170 Hz or can I set it someplace that I haven't found?
Q2. Is it the same for my brother's Omni 6?

Tnx 73 Art
