As I have written about many times in my monthly MT Milcom column, DoD continues to cleanout selected aeronautical frequencies in the new 380-400 MHz LMR subband to make way for new LMR (Trunk and Simplex) and wideband assignments.
The latest shoe to fall is the last command post on 383.200 MHz (Scott AFB) that has now moved to its new home on 349.400 MHz, a USAF natonwide Command Post frequency assignment.
There should be no more CPs on 383.200 MHz and that frequency is now part of a new wideband subband within the 380-400 MHz frequency range.
