2 Meter AM frequencies seem to be geographical (see
http://www.amwindow.org/freq.htm)
I've also heard a few guys in metro NY/NJ operating on 144.27 MHz The new OSCAR subband is now between 144.3 and 144.5 MHz. Beacons are between 144.275 and 144.3.
Our next charge should be to get the ARRL to change the ARRL band Plan for 2 Meters. It presently states 144.200 to 144.275 MHz - General SSB Operation. It should be changed to "General Phone Operation".
