Keep us posted on that one. I still haven't had time to come up there and do it myself!

BTW, it's probably not a P-25 system. Most likely a Motorola Type II using P-25 voice. You will need some base, step and offset values to track it...


Wilco...Thanks for the tip; I saw a note about the (Long Beach? Colorado?) BOP system not being true P25, but glossed over it.

Flash provided the Base, Offset and Step values (406.000/397/12.5) elsewhere but I need to work out the lo-hi values. I'm going to go with 397 and 759 initially, then work from there.

More on it this afternoon...Maybe.

If I have time and gas, I may try McChord again today, armed with differeing lo-hi values.

It should be able to do IWN out of the box, it's pure P25 with no settings. If you're where I think you are, try Grass Mtn 167.6125 or Tacoma 167.2125. TG's in the 13xxx range.

Ft Lewis/DOD 380 TRS:

control channels:

380.075 (site 01) Is at Madigan.
385.3125 (the radio tells me this is Site 02) booms in from Steilacoom, so it's across the water or maybe at McNeil Island?

Add voice channels

381.0125

TG 8616- Range Control, unk range.
===================================

I should be southbound soon; will check the Roy area and see which site covers out back.

Fort Lewis/DOD System stuff:

The 380.075 (Site 01) is at Madigan Hospital

The 380.2125 (Site 02) is either coming across the water, possibly from McNeil Island, or is at a very high point above Steilacoom, in the area of Pierce College?

The 380.725 (Site 03) is somewhere on the east side; was very strong south of the Roy 'Y'.

That 385.3125 (Site 002) is not affiliated with Fort Lewis, as far as I can see. The only traffic I caught off it was encrypted stuff in the 23xxx talkgroup range- probably Navy.

I can't find 380.3875....Maybe this is a fill-in somewhere?

So Fort Lewis is affiliated with the regional DOD 380 system, but on it's own seperate zone with 3 sites, methinks. They share the system ID of 14C, but use a wholly different site numbering scheme.

Oddly enough, when I was on the south side, in Yelm, I could receive voice traffic on some of the 380 channels, but could not locate a control channel anywhere. The voice traffic was so strong, and obviously not conventional, I started thinking SCAT on several freqs as fill-ins, but when voice comms went away, there was no control sound or data. Hmmm...

================================================================================

Today's talkgroups included:

8103- Military Police Ch-3
8104- Various gate guards calling in vehicle counts for the hour
8107- Military Police Ch-1

8332- Range Control, possibly patched from VHF, as intermod kept opening up the channel and even started interfering with comms.

8514- These 4 are all affiliated with the same unit, used for training purposes.
8515 "
8516 "
8517 "

8549- MagComm and Security-1, possibly security at some sensitive area?

8552- More training comms, at range- 250 soldiers and 55 humvees on the range

8616- Range Control again

I can't find my notes right now, but there is a site 104 in the 380 range I picked up just above the Vernita crossing near the Yakima Range.

Let me know when you can monitor Fort Lewis Fire Dept. They have 5 Stations with 25 Miles of I-5 that is their First Due and are very busy.

Two new ones today, both conventional:

406.500- All DES-OFB encryption. This was a phone patch freq for McChord AFB, IIRC. Not part of the McChord TRS though.

407.300- Phone patch with 100.0 pl tone. This freq was one of the original Ft Lewis TRS analog freqs, back in the day...The conversation was something to do with bathroom maintenance (!).

Thoughts?

All- Our very own Chris Parris has done an AWESOME article on the 380 DOD system in the Puget Sound area. It's in the May issue of Monitoring Times.

I'm just going to keep updating these as I get them.

On the Fort Lewis system today:

8106- Camera and alarm techs, poss at the 1st SFG.
8224- Two guys just chatting, cursing.
8611- Sounds like an field training exercise for mil police, running a compound for 'detainees'. Cellblocks, towers, less-lethal rounds deployed, mealtimes, and mentions of COB role-players.
8612- Same as 8611
8819- Poss dial-a-ride? Transportation units giving soldiers rides to/from Madigan. Civilians used.

23808- On the DOD regional system, PSNS fill-in site (02). Security or police, half clear, half DES. Mentions of alarms, convoy route security. Mike units.
