Digging through handwritten data from a prior trip up I-44, I recorded the NAC for this sys 037 is also 006,
not 150. (Also as in also the same as Site #). I had logged this new system 037 three weeks previously while driving thru the Ft Wood area, in addition to the well-established sys 028
US Army Fort Leonard Wood Trunking System, Fort Leonard Wood, Missouri
Unfortunately, no other 4## freqs were heard that are not on 028, or that had a NAC different from 191/192/193, which are used by the old 028. system.. I'm pretty sure now this is another system ID at Ft Wood, perhaps stealing some freqs from sys 028. Why a separate system? Sometimes I have seen that in larger systems/zones.
FWIW I did log 409.1125 noted above but with the NAC 193 which is the SYS 028 Front Gate SIte 3 freq. ALso, 2 control channels in the 028 system 409.3625 and 406.5625 had the regular P25 buzz with a 3-5 second "water drip" or beep which I think indicates Phase 2.
