Some recent changes and new frequencies for several UHF federal
and military systems have prompted me to remind everyone of the
upcoming deadline for narrowbanding the federal UHF band.
The January 1st 2008 deadline for the 406.1-420 MHz band to narrowband channels from 25 KHz channels spacing up to 12.5 kHz. Some agencies will be changing frequencies and some trunked systems may move off of their current UHF channels. Expect to see many changes between now and the end of the year, and even after the deadline has passed.
