[Scan-DC] NPS-Capital Parks

[~Bill]

Would not surprise me if they are using SINCGARS on Low Band
Even though our (Massachusetts) has access to the State 700/800 as well as their own VHF High, we still find them with a little patience with 30-54 use

Apparently, they are mostly on the DC P25 network, mostly TGs in the 114xx
range.

But I wonder if they have any "company channels" in those humvees?

Alan
