[aprssig] RFM22B UHF Transceiver Module

[John Wiseman]

Bob.

Depends what you mean. The interface into the TNC from the application is
ax.25. The on-air modulation and packet formats are not the same as current
TNC's. So you need an RFM module at each end of a link, but it should work
with any KISS-enabled application.

I assume you are not making it AX.25 compatible at this time.  That woule be
an entire additional leverl of effort to make it compatible with existing
APRS radios and their 9600 GMSK of AX.25...  bob
