Right.  The actual frequency doesn't matter.  An APRS cell can be set
up on any frequency as long as you have one iGate linking it to the
APRS-IS. Ideally beacon the existance of that system on 144.39 so
others know where to join the fun.

A second iGate for backup and a couple core digipeaters make it into a
real useful system.
