[Alexandria Radio Club Reflector] 33cm/900MHz Juggle Net

[Ian]

Attached are area 33cm repeaters and other recommended channelization.
Channels 1-9 should not be moved around as they correspond to the
channelization that was programmed into a group of Motorola GTX900
handhelds we purchased a long time ago and those are rather challenging to
reprogram.
