222 is probably the best band I've ever run packet on.  Again, the 
difficulty is in the cost of 222 equipment compared to 144 or even 430 
equipment.  As for unused frequencies, that is a problem on almost every 
band in Southern California.  It is near impossible to put up a repeater 
on 2m, 220, or 440 anymore.  We have had issues with proposed UHF APRS 
frequencies in the past because they have always been in the 440 band 
and on a .025 or .050 or .075 channel.  We are 20khz now.  I'm not 
trying to suppress the effort, I'm just realizing how difficult it will 
be to nationalize additional channels!
