[aprssig] Best TNC for use as portable digi?

I got another batch of proto C boards in, but only a few processors and I
don't have time to build any myself at the moment until I get settled into
the new house.  You might be able to use a T2-135 board (the internal type
for the DR-135T) but it's built for a radio with no pre/de-emphasis.  It's
small and light, though.

I *might* be able to scrounge up one of the original prototypes, built to
fit the same case as the original OpenTracker and the TinyTrak3.  Only about
half of them worked, thanks to a problem with the oscillator circuit.
Without the connectors it only weighs a few grams - what's your weight
budget?
