New Auburn/Lewiston 800MHz P25 Radio System

Post by ChrisP »

It appears to have started coming online this week (thanks to Jim over at RR for the heads-up). Currently CC is on 856.0125 with a NAC of 032. Unknown if it's currently one or more sites (out of five, I believe) active. No TGs logged yet.

Thanks Chris,

I created our Wiki page for this system. As we ID users and frequency info, things can be added to the wiki.

https://scan-ne.net/wiki/index.php?titl ... onal_Trunk

Also this is going to be the official thread for that trunk.

I can confirm that the Goff Hill site in Auburn is live - full CC signal with no antenna attached at the corner of Court St and Park Ave (and surrounding area) in Auburn.

NAC: 032
SysID: 032 (not a typo - same as NAC - is this common?)
WACN: 00552

I had CC on 857.4625 (as MaineRadioMan mentioned), but it seems to be back on 856.0125 now.

Yes it is Common - Mass ComIRS is Sys D14 and uses various D1x NAC per site, one is D14

Well, looks like the system is online and active for both Auburn PD and Lewiston PD as of this morning (see Sun Journal FB link below). Bad news though: both are fully encrypted.

I can confirm talkgroups 101 and 201 are both active and encrypted this morning. My guess, based on the fact that Auburn PD unit numbers were always 100-series and Lewiston PD were 200-series, that TG 101 is Auburn PD, and 201 is Lewiston PD, but that's just an educated guess.

Fire departments are still on VHF for now. Hopefully they're not encrypted when they switch over.

Also, FWIW, looks like they are using the P25 Phase 2 (TDMA)

IIRC the NAC and System IDs being the same are a Harris thing. And if this is in fact a Harris system, remember that all frequencies can be control channels.

I had heard a rumor that Lewiston was going ENC, so I am not surprised. Not surprised to see Auburn as well. I know both cities are having some serious crime issues.

Lewiston PD and Auburn PD are completely online and completely encrypted. Fire is expected to move in the next 3-6 weeks but will be unencrypted.

TG 501 has been very active yesterday and today. I can't tell if I'm just barely out of range to accurately decode or if it's encrypted, but I've yet to hear any clear voice to ID.

Interesting that the Fire Departments haven't transitioned to this system yet. It's been about 8 months since Police switched over. I wonder what's causing the delay? Guessing maybe supply chain issues (like everything else)?

Does the trunked system have the ability to patch mutual aid units into the trunked system? The FD's may not want to lose communications with their mutual aid partners on who are on VHF.

My understanding (from posts here and on RadioReference) is that the system will have patch capabilities for mutual aid situations. This is purely secondhand information - no idea of the details.

I've noticed a couple of interesting things over the last week or so:

- UNencrypted traffic on TGs 401 and 402. TG 402 was definitely firefighters with air packs on. Sounded like they were working an actual fire, but I'm wondering if it was training. I've also realized (from the weekly radio test on Lewiston FD's VHF channel) that Lewiston Fire unit numbers are in the 400-range. If we apply the same logic of TG101 being Auburn PD (with 100-range unit numbers) and Lewiston PD on TG201 (with 200-range unit numbers), I'm thinking TG 401 might be Lewiston Fire, and 402 might be Lewiston Fire TAC, TAC 1, or something similar?

- Auburn Fire unit numbers are in the 300-range. Maybe TGs in the 300-range will be Auburn Fire?

- I've noticed encrypted traffic on TG 102 and on TG 202, most notably on TG 202 when there was a major law enforcement situation happening in Lewiston. Traffic is infrequent, but heavy when it does occur. I'm thinking these are Auburn PD and Lewiston PD (respectively) TAC channels.

- Random encrypted traffic on TG 501. No idea what that's all about.

- The old PD VHF frequencies (159.150 for Auburn, 158.790 for Lewiston) have been active with encrypted traffic with a NAC of 032 (same as the trunked system). I haven't correlated traffic there to traffic on the trunked channels, but maybe it's some type of patch for law enforcement mutual aid?

Any updates on the Auburn/Lewiston P25 P2 system for talkgroups. I heard Auburn Fire Dispatch announce to switch over to the "new 800 mhz system" at 0903 on November 16th, then the VHF channel went dead. I believe the are using the new system, but no new posts has been listed here or radio reference.

Later in the day, Lewiston fire got the same announcement to switch over to the new system. The time that Lewiston switched over was around 1300 on November 16th.

In this thread and other threads out in internet land. People have talked about both Auburn and Lewiston having multiple channels so that they are not on their dispatch channel all the time. Curious if anyone has identified the talkgroups.

Apparently I am going to have to upgrade my old scanner to get P25 Phase 2 capability.

Definitely a sharp increase in traffic on TGs 301 and 401 yesterday and today. From what little I can make out, it does sound like fire traffic. Unfortunately I live right in the fringe reception area, so I can't hear them clearly most of the time. Also, Auburn's VHF channel does still seem active (although maybe less active?). Just heard dispatch on it as I was typing this.

Again, I *assume* 301 is Auburn and 401 is Lewiston, but have not 100% confirmed.

I also had a couple hits on TG 310, but could not make out the audio.

The information that I have been able to gather is that Auburn Fire and Lewiston Fire are rebroadcasting their new dispatch talkgroups on their old VHF system. This was setup up that way to have communications with mutual aid coming in to their perspective cities. The units and dispatch are all on the new 800 mhz system. The fireground/tactical talkgroups are not connected to the old VHF system. It has been mentioned in the past that they might have to capability to patch in some VHF channels to one of those other talkgroups to expand the mutual use.

Auburn PD and Lewiston PD started the rebroadcasting sometime after they switched over to the new system. Unfortunately, they encrypted those old VHF channels. I believe about 6-8 months ago, Androscoggin County Sheriff did some radio updating. The sheriff's department stated they were doing the radio updating at their future location on Center street. Wondering if Lewiston-Auburn 911 provided the encryption key to allow them to talk with Auburn or Lewiston PD via the old VHF system.

Hopefully someone that lives closer to the new system will be able to provide updates of the new talkgroups.

The 911 center was doing testing with Poland Fire on Wednesday and Today. Another curiosity of what has changed between the two.
