Found another site on the DOD regional system:

Site 001
Control channel 385.0625
Voice Channel 386.4875 (only one noted so far)
Talkgroups-
23583- Only DES noted
23625- Only DES noted- very active

This was a 99% strength in SeaTac near the airport, atop a hill, so I figure it's across the water. I can't hear it from the South End, so maybe a small filler near Port Orchard?

I really need to take a trip over that way.

Glad you caught that one, Wil. I never heard it while driving up past Bremerton, Bangor and points north. I always suspected it might be over on the Seattle / Tacoma side of the Sound, but never did catch it on my radios.

Don't thank me yet, Chris, I'm not entirely sure that 001 is on the east side of the water. From my location, I could see across the water to the Vashon/Peninsula side.

Okay, I was wrong. It's not at Madigan, but in that immediate area. Verified in person today.



Wayyyyy off; this site is located at Gray Army Airfield, on the hill on the east side of the field (up the hill from the field house).

Still looking for the site for the east fill-in channel, 380.725.

I've never seen a site number below 100 on this system. I show 385.0625 as site 101, and seems to be colocated with 380.3875 site 101 at Ft Lewis. At least it gives close-call hits on I-5...

My suspicion is that the Army portables use the 380-385 range and the Navy uses 385-390, at least that's the way the talkgroups seem to come up. (There is a USMC detachment at Ft Lewis).

Here's what I have:
101 101 Ft Lewis
102 102 Ft Lewis
103 103 Navy Reg NW Bremerton
104 104 Navy Reg NW Kitsap
105 105 Navy Reg NW Bangor
106 106 Vantage??? etc? (YFC)
107 107 Vantage etc? (YFC)
108 108 Navy Reg NW KNUW?
109 109 Navy Reg NW KNUW?
110 110 Navy Reg NW
111 111 Naval Support Ctr Arlington
112 112 NavSta Everett
114 114 rumored but never heard
(at least one of these is Indian Island, per another post)

Also, on VHF, the non-mil counterpart:
101 Lookout Mtn Bellingham
102 Blaine
103 Port Townsend area
105 Striped Pk Port Angeles
106 Seattle Federal Building
107 Gold Mtn Belfair
108 Grass Mtn Enumclaw
109 Marysville SR-9
110 Tacoma
111 Olympia
112 Baw Faw Pk
113 South Bend
114 Kalama
115 Vancouver WA
116 rumored Mt Vernon???
117 Keelers Corner SR99/150SW
118 118 Cougar Mtn Bellevue
119 Mt Scott Portland OR
120 Germantown Rd Portland OR
121 Metro Portland OR
122 Gresham OR
123 Beaverton OR
125 KSEA Terminal
w mon Naselle Illwaco
x Hanford
y mon 171.4375

I should point out that my PSR500 only displays the sites for this system as 01, 02, etc.



I have 385.0625 as one of the Navy/DOD sites, somewhere west of Vashon, also site 1. I still haven't heard anything on 380.3875 at either Fort Lewis or anywhere else. Also, Sunday, I drove ALL over freaking Fort Lewis and only heard the three control channels I've mentioned, and that included searching 380-400mhz.

I show 380.075 and 380.3875 as alternate control channels for the same site, so that's consistent with your results.

Flash

Got it. FWIW, I still haven't heard the primary site on anything but 380.075.

The Navy system doesn't let Army users roam onto it; likewise the reverse.

Great info, thanks.

Interesting that the Navy lists of neighbors don't agree. I suspect they might be transmitted at irregular intervals, maybe the logging program needs to go longer.

103 is SW of Bremerton. 104 is the Bremerton Annex / hospital, while 105 seems to be near or at Bangor. They seem to count up going north, so the missing numbers on each list aren't only due to distance.

Flash

One of these days soon, I'm going to devote a full day or so to logging these sites and info...This was a quick run of about 20-30 minutes only, thus the potential for some conflict.

Thanks for posting these sites, Wil. Did you actually hear the Navy Tower 101?

Also, for some reason PRO96COM is mis-reporting the transmit offset on the Navy sites, but not the Army ones. The standard TX offset in the 380-400 MHz DoD land mobile band is 10 MHz. For some reason on the Navy sites, it's reporting it at 20 MHz, which shows some input frequencies that are not possible.

I think I looked up some of my original logs from the first time I started picking up the 380 MHz control channels and the Navy sites I first heard were reporting the TX offset correctly. They must have changed something since then...
