[arm-allstar] picking frequency

[Doug Crompton]

Ron,

 I am not aware of any US reassignment of the 420-430 part of the band. ITU
region 2 has that entire spectrum. We are however secondary to the band to
the military and in some areas near military installations power is
limited. Around PAVE-PAWS military radar sites there is generally a 100
mile 50 watt limit.  I know there are coastal sites in MA and CA but not
aware of other states.
