U.S. Open Update

Thanks to posts in the Maryland forum of RadioReference and on Scan-DC, I've been able to compile a list of talkgroups in use on the Montgomery County trunked system. Here is a list of what has been active yesterday and today:

1744 Special Events 1
1808 Special Events 3
7056 Traffic Management Center 1
15696 Special Events 5
17200 Special Events 6
32336 Regional Police Interoperability

Also, it's been confirmed that some of the tournament organizers are using MOTOTRBO on at least a couple of frequencies (452.3375 and 452.4125).

I'll continue to update this blog as well as my Montgomery County page throughout the weekend.
