Houston Federal Interop Test

Another testing of a federal interoperability system was noted by listeners in the Houston, Texas area last night. Radio checks from various local and many federal agencies were heard. In some cities these tests seem to come at a set time every week. This test in Houston occurred at 3:30 AM. They may mix up the times to keep people on their toes...

As noted in a previous blog entry, the Houston federal interop channels are:

L1 - 170.7250 MHz, P-25
L2 - 171.4375 MHz, P-25

Also some testing of a patch between L1 and the Houston Police Citywide channel of 460.4250 MHz was heard.

These same frequencies appear to be used as interop channels in other cities, so give them a try and see what you might hear.
