I've received some reports from the Dallas Ft. Worth Metroplex of a new DHS Immigration and Customs Enforcement repeater in operation.
The P-25 repeater is on 163.7000 MHz with apparently two input frequencies, 162.8500 MHz and 168.9750 MHz.
I am currently working on an "Up Close" look at ICE and their radio systems for a future Fed Files column, so if you have any frequencies of interest, feel free to pass them along!
