After my recent trip to Arizona, I decided to dust off my listings for the DHS Customs & Border Protection Border Patrol. The Border Patrol continues to use its legacy VHF frequencies that are in blocks assigned to the Justice Department.
Currently the CBP Border Patrol doesn’t have a national channel plan like some agencies, but assigns their frequencies as needed locally. Along both the northern and southern border areas (except for southern California), the 163 MHz frequencies are the “backbone” repeaters with multiple input frequencies, from the 162 MHz, 165 MHz and 168 MHz blocks of frequencies. These frequencies can be used as repeaters or “local” simplex frequencies as well.
In areas not near the US borders, the former US Immigration agents, now part of DHS as the Immigration and Customs Enforcement may use frequencies from these blocks for local use.
Besides the frequencies listed above, most CBP Border Patrol units have access to the national CBP Customs radio nets listed in a previous blog entry:

The above link contains some interesting information about the project and its use by various agencies so far.
The IWN expanded it's coverage from Washington State down in to Oregon and the Portland metro area in late 2006. It now appears to be in full use by Portland area federal agencies. We've been monitoring a LOT of activity on the system in the last month or so, almost 24/7. Several talk-groups on the system are showing the majority of the activity, but since the radios have been set up with the encryption selected automaticaly, I haven't heard any clear transmissions since the radio techs finished with their installation tests. But remember - systems are not encrypted, talk groups are not encrypted, but it is the individual radios that are encrypted.
So where will the IWN show up next? Information in the above referenced audit report confirms that the southwest US is the next region to start the build out. I am currently in the Phoenix area (more on that in another blog entry) and have noted there is a P-25 control channel on 165.6375 MHz. It is part of the Phoenix area P-25 trunked system that allows federal VHF users to tie directly in to the 800 MHz system without patches.
Here is some budget information for the IWN project:
So keep a lookout for P-25 control channels showing up in the VHF federal band in your area!
