DC INTEROP (DOJ "25 Cities" Project)

[KF4ZTO]

While the RR Database lists "DC I-O 1" and "DC I-O 2" (the only one I've heard activity on is DC I-O 1, 159.150 MHz), I've read on the Monitoring Times blog about three other "DC Interop" frequencies as part of that system. These are

“DC I-O 2 N” 173.7500 MHz
“DC I-O 2 S” 168.0875 MHz
“DC I-O 2 W” 166.7875 MHz

Has anybody heard any activity on these frequencies? Should they be added to the DB?

I can only say [my experience during the 2009 Inaugural] that I heard
159.1500 [IO-1] and 168.8750 [IO-2] YMMV

I don't think those three have ever been used - that's why they're not in the database. 159.1500 and 168.8750 are used, however.

^Makes sense. I'll put these in my scanner and post on here if I ever see them active.
