386.4 Control Channel

[zguy1243]

Noticed a new control channel pop up on 386.4 mhz. Signal is S-9+10 in Gordon county Georgia. I have no P-25 capable radio. Signal was received on a UHF discone at 110 feet AGL. Anyone else copy this or have it logged?

Not a CC. P-25 encrypted with a NAC of 028. Got it at 3 bars on my 106 in N Gwinnett on a 2/440 dual band mag mount on a 4 drawer cabinet

Another frequency to file away with all the other Gwinnett channels?

I don't think so /\/\ike. It is stronger up by Jody. I'll keep it in my scanner and monitor it once in a while.

386.4 is VERY strong here. Its so strong I would say its not that far from here. I would assume this would be a Military user? I am not up to speed on the trunked and digital systems really. There has been non of this kind of thing around here till now. I am really curious on this one...

I'm thinking maybe Camp Merrill. Not far from you in Lumpkin County. It is a P-25 digital signal. It is simplex, or maybe a repeater. Trunked systems don't have NACs. Maybe someone in that area has a GRE, or RS scanner to monitor.

Not Camp Merrill. They still use the Black Mountain EDACS Site (seen on Lumpkin County's page). Just talked to a ranger the other day, no changes on their system. But there are new buildouts, so I'll keep looking (and you all do the same) and maybe we can figure it out!

 

[grem467]

Trunked systems don't have NACs. Larry

P25 and P16 Mixed Mode ones do.

 

[N8IAA]

P25 and P16 Mixed Mode ones do.

My mistake. Yes the P-25 do Who has a P-16 mixed mode around here?

I have been monitoring the system for the last two weeks now. It is a new 380-400 MHz system from Camp Merrill in Lumpkin County near Dahlonega . The site you are seeing is Tower 1010 probably on Black Mtn. There is also Tower 909 currently on 386.850, but they have tested another freq. There is more, but I won't pass that along just yet. The new system is just started in the testing phase two weeks ago and I do not want to put additional info out until they get out of testing and we can see things stabilize. This is System ID 01e, which is part of the Fort Benning 380-400 MHz TRS. I will have more on the MMP blog when things stabilize out.

Good to know! I am getting it well now that I know what I'm looking for. I assume it is like many of the other bases that have national P25 systems connected - guess it's as good a time as any to phase out the EDACS!

 

[MtnBiker2005]

So...
Who will be the one to study this new stuff with Pro96com software. and report back with the logs(tower.txt) etc.

Guess that is me. ;-)))

I have been studying this new portion of the Fort Benning TRS since it first came on three weeks ago with Pro96com/Unitrunker. Since the system is still being installed and changes are likely I won't throw a lot of details out until things settle down after the testing phase.

Here are a few details that have remained constant during the last three weeks of testing.

These two new sites are a portion of the Fort Benning, GA 01E TRS. WACN 90b20.

Tower 909 has two cc freqs IDed 386.8500/396.8500c 388.1750/398.1750c
Based on monitoring this appears to be the Black Mtn transmission site. the PSR-500 is reporting a NAC of 027.

Tower Site 1010 has had three cc freqs 386.4000/396.4000c 388.0000/398.0000c 388.7000/398.7000c
These were seen for the first time yesterday afternoon when the first voice channels came online (lots of mike blowing and 1-2-3-test). Tower 1010 appears to be on Brawley Mountain and a NAC of 028 is being reported by the PSR-500.

The radio techs on Tower site 1010 are using TG 3001.

More to follow and a final report will appear on my Milcom Monitoring Post blog (address in sig block).

I'm hearing the Brawley Mountain site quite well in Gwinnett. Pro96com just showing the 386.4 CC with ST! under the Status of the system. Not hearing anyone talking. Using my 106.

They did a hand full of voice checks this morning arounf 0905 and haven't done anything sense. You have the same info I am seeing up here except the fillin of freqs this morning thanks to the voice checks.

386.4000c
388.0000v
388.2500v
388.7000v

Again it was TG 3001 with radio units 300001 and 300002 as part of that group.

As I mentioned in my first post things are still a bit sketchy regarding this system and that includes which tower belongs to which transmitter site. Because I am so close I have flipped back in forth on which tower is Brawley and which is Black Mountain. Today Tower 909 looks like Brawley and 1010 looks like Black Mountain based on signal strengths.

So here is the deal. Larry's post above got me to thinking. I know based on monitoring (thanks to the CW IDs) the EDACS system sites at Merrill which is which. So Larry, if you would be so kind and check the Merrill 400 MHz EDACS system and let me know which EDACS control channels you are seeing and how strong?

Here are my notes on the EDACS system:

Black Mountain Site 002: 407.2250 (LCN1) 407.5250 (LCN2) 408.0500 (LCN3)
Brawley Mountain Site 003: 407.2500 (LCN1) 407.3750 (LCN2) 407.5750 (LCN3)

So Larry, which of the EDACS system are you hearing and how strong???

I hear the Black Mountain site 99%. The Brawley Mountain 00%. Just the opposite from the 380Mhz frequencies. Monitored the Battalion TG as I was typing this.

See Larry! There is something to listen to besides Swinenet County!

/\/\ike, did you think that I bought the 106 just to listen to Gwinnett??? I got tired of carrying two scanners around for all the monitoring that I do))

Rod from the Milcom mailing list found another site 808.

Plus some new information is posted on the mt-milcom blog.

I found Site 808 using a control channel of 388.025 active this morning using a BC396T. It shows 3 bars on the S meter, were 386.4 only shows 1 or 2 at best. From my location I'd guess Site 808 must in the western part of the N Ga mountains
