Justice IWN Marches On!

Until recently the Justice Integrated Wireless Network (JIWN) testbed trunked system operated within the state of Washington, but now the system has started to creep south into the Portland, Oregon area. Last week several new P-25 VHF control channels suddenly hit the airwaves. A group of us in the area have started trying to map out these new sites as they come on line, and here's what we've found so far:

170.7250 Site 119 Portland-Mount Scott
170.8375 Site 119 Portland-Mount Scott
170.9375 Site 119 Portland-Mount Scott
172.0625 Site 119 Portland-Mount Scott
172.2125 Site 119 Portland-Mount Scott
172.4125 Site 119 Portland-Mount Scott
167.5125 Site 120 Portland-Germantown Rd.
167.6625 Site 120 Portland-Germantown Rd.
168.5875 Site 120 Portland-Germantown Rd.
168.9125 Site 120 Portland-Germantown Rd.
169.2375 Site 120 Portland-Germantown Rd.
169.9375 Site 121 Portland Metro Area
171.6625 Site 121 Portland Metro Area

170.8625 Site 122 Portland Metro Area
171.6125 Site 122 Portland Metro Area
172.1875 Site 122 Portland Metro Area
167.6125 Site 123 Portland
170.9875 Site 123 Portland

This information is very preliminary. We've been hearing the radio techs setting up these new sites and testing various systems. Some of the sites have not been activated yet, so more frequencies will be coming soon. Most of the traffic has been un-encrypted, but encryption has been the primary mode on the rest of the JIWN system.

Press reports indicate that final contracts for this nationwide JIWN project may be finalized by early 2007, so we'll see when this system starts appearing in other parts of the country.
