Reducing all systems to 12.5 kHz will eliminate the adjacent channel overlap at UHF, but what about VHF?
A – The reduction to 12.5 kHz equipment reduces much of the adjacent channel overlap at VHF, but since the band is channelized at 7.5 kHz, there will still remain some level of adjacent channel overlap with 12.5 kHz equipment. Thus, adjacent channel coordination for 12.5 kHz systems will still be necessary.
