[FedCom] New Federal Channels and the GRE PSR-500

[J&D Schnoor]

I want to create a file of conventional frequencies in my Butel ARC500 for 
my GRE PSR-500 of exclusively federal VHF and UHF frequencies from 162 to 
174 and 406 to 420 mHz.  I want to scan them in just the P25 mode with the 
SQ Code in the search mode so that when it displays a NAC code I can store 
it quickly.  It appears as if I can actually store 1852 conventional 
frequencies in the GRE.  I want to make the best use of the available 
memory.  I have programmed is sequentially in 12.5 kHz steps.  I have 
removed 162.3875 to 162.5625 (weather and a channel on either side).  I seem 
to recall some other "holes" like SCADA in the 170 region.  Also, are there 
still some holes between 406 and 420 where there simply are no two-way 
channels allocated?  Or has all of that changed in those bands?
