[aprssig] Paths - Solution proposal

[Andrew Pavlin]

You mean like the 70cm "brick" data radio that NW Digital Radio is making (the UDRX-440)? Not sure if that price is low enough, but it already has a computer built into it (which saves on that cost re: the T3-9670).

Exactly.   The technology in the network does what it needs to do and
shields the user from the complexity.

Too bad we didn't have a low priced small data radio with 9k6 (at
least) ready to go to experiment with this.   You know - like the
T3-9670...  :)
