[MilCom] Uniden Bearcat BCD996T and FM low band

[J&D Schnoor]

I haven't done much military monitoring for a while.  I recently purchased a 
Uniden Dearcat BCD996T and I am running it with the Butel ARC996Pro 
software.  I am thinking of doing a search routine for the VHF low band to 
catch Arny National Guard Aviation.  I am thinking of programming 30-50 mHz 
with a PL of 151.4 hZ because I seem to recall the military using their "new 
Squelch" of 150.0, but that the EIA standard 151.4 hZ would be close enough 
for monitoring.  Anyway, for those familiar with this scanner, should I 
select FM or WFM?  I assume NFM is too narrow of a filter.  I thought that 
the deviation on military Fox Mike is something like 45 kHz wide.  Also, is 
the band actually just 30-50, or do I extend it up from 30-76 or 30-88 mHz. 
The other thing is steps, of course.  At one time I seem to recall that the 
steps were about 50 kHz, but have they gone to 25 kHz increments now?
