Yes, but I wanted more control.  They're not as easy to integrate, but 
I've written the required code (including some forward error correction) 
for the OTUSB/T3 so that part is no longer an issue.  The tracker board 
functions just like any other OTUSB and supports APRS messaging, KISS, 
and so on.

I'm hopeful that I might even be able to get them to interoperate with 
standard G3RUH 9600 baud TNCs, but I haven't dug into it enough yet.
