[ANSS-netops] EB3-Plus radios and replacement

[Meremonte, Mark]

We use the GE MDS iNet-II 900 MHz spread spectrum radios but they are
expensive and fairly complex connecting to to loggers via serial port and
unable, with version we have, to select specific channels to utilize.
These radio specs look very good.   Interesting Avalon radios have ability
to Tx at 1.7W rather than the FCC requirement.
