[drats_users] Correctly configuring D-Rats to talk to myself

[Michael A. Waldron]

Just thought I'd update the group and close this issue for future searchers. 

After extensive testing using a 2820, 800, 91, and a 92, I've concluded that my 91 is just plain broken.

Everything else talks to each other, the 91 just doesn't do slow speed data. Every packet it sends is corrupted. I suspect that the voice packets are probably not quite right either but the forward error correction that gets applied to the voice side makes them work. 

I suppose that's what I get for $200 at a hamfest, I shouldn't complain. I'm wondering if it's worth sending it in to be looked at. I may try swapping the UT-121 unit with someone elses to see if that is the problem or if it's elsewhere.
