[aprssig] transceiver for APRS?

[Chris Kantarjiev]

A friend and I are thinking about design projects, and one that
came up is a transciever specifically for APRS - something like
the Maxon data radios of years past.

Aside from "almost free", what features would you want? The ones
that came immediately to mind were
	- low idle current
	- 9600 bps capable
	- frequency agile (with some work, perhaps)
	- no voice frequency pre-emphasis

What else? What power range?
