Default Cheap, Small TNC?

I was working on designing a surface mount PC board to build up a
bunch of Bob Ball's nifty $25 PIC-based TNCs together so every RACES
radio would have one built-in. . . and then read the source code and
discovered it doesn't do AX.25 connected mode!

Any suggestions for a TNC that:
- Is cheap enough I can afford to give away 20 of them,
- Is small enough to install inside a mobile radio,
- Is AX.25 connected mode capable,
- Is NOT KISS or APRS (UI) specific,
- Is NOT dependant on ANY PC interaction or support,
- Will digipeat.


Bill -

The NO KISS specification I think eliminates the John Hansen products ?


From a practical standpoint, I can't see much difference, unless OP has some
specific software beyond the typical terminal emulator. The TNC-X works
quite nicely from a laptop and a mobile (haven't tried it with a hand held).
And consume little power.

However, they don't digipeat without the addition of a daughter card, and
that would drive the price up, maybe too high
