I have one. I have not used it for any kind of packet.

Page 26 of the User's Manual goes into some detail; the radio offers flat
audio out, apparently also flat TX audio in:


The radio specifically supports 219MHz data operation, too. I have
found Bridgecom to be responsive in the past, perhaps you might
want to contact their customer support.
