Thanks for the info Jason. I remember the information I found was somewhat
limited, so it's nice to hear of some real-world experience. I'm guessing
those issues may have contributed to them being pulled.

Are you running 9600bps with the HT's? If so, how are you interfacing to
them? One of my applications would be running plain 1200bps so most
anything can handle it, but the other would need direct connection to the
modulator/discriminator and no pre-/de-emphasis to run 9600. There is also
some experimenting I'd like to do with the higher data rates of the
Direwolf modem.
