Burlington Hydro

[VA3SOM]

Has anybody heard Burlington Hydro as of late? (past few months), on a SDS 100/200 and not hearing them at all, but instead it just keeps locking onto the channel from time to time Flashing DMR/Slot1

Trying to figure out if maybe i need to try and set it up as a trunking system or do something, or did they go silent/enc?.

If its saying DMR try programming it as a One Freq Trunk and use Analyze and Discovery. This should give the Color Code and any Tgs active on it.

I am the one that submitted that a couple months ago. If I remember it correctly the 166.5000 is used for data I think, and 169.2900 is used for the comms.

Ah, ok will try programming 169.290 into a DMR one site system maybe. Not sure why I have not heard that at all even during the major storms a while back. The Data on 166.5000 explains why it is locking on, thanks!.

Bumping this up to avoid making a new one.

So a few weeks ago I heard it clear and they were talking again, first time in months, then today I heard something very odd. Sounded like data/major interference/RX issues but then it sounded like encryption, on both the Ops and other channel.

https://cdn.discordapp.com/attachme...828577871790120/audio_2021-03-17_15-33-04.ogg managed to capture a very short audio recording of it, at the end heard what sounded like sorta encrypted voice.

Any thoughts? did they go ENC? or switch from DMR to something else?

I agree it sounds like encrypted voice.

Is this the same talkgroup as before or a new one? Was the clear transmission before on talkgroup 100?

Yea, it def was ENC. This was on the conv DMR frequencies, both of them I was hearing ENC on actually both that are listed as TG 100.

As I type this, I, just heard it again on 166.50000, very clear ENC sounds.

If you are using an SDS it should show ENCRY on the screen (at least I believe it does for DMR)...

 

[VA3SOM]

I looked to see if it showed it but was not seeing it, could it mean it was Soft/partial ENC?. Will look if i see it again but iirc i did not see it each time.

 

[gary123]

I listened to your capture. It may not be encrypted. It almost sounds like improper decoding of the received signal. A longer capture will tell a lot more. Even with the scanner auto muting the enc. This is one of the reasons I wish that the auto mute was a optional enable/disable feature.

Are you getting a consistent TG and a consistent ENC when they are talking?

It is hard to say. I had someone I know say it could be soft/partial but then I hear what sounds just like other ENC sounds from other ENC'ed systems, such as McMaster University. As i type this, it is still happening best recording I could get.

No ENC symbols at all on the screen and no hint of voice.

Improper decoding, could it have been they switched modes, or changed the type of DMR it is?.

I have DSD+ on the 166.5000 right now and will keep an eye out on any transmissions and let you guys know what it says.

That definitely does not sound like your typical encrypted DMR.

Monitoring both frequencies in parallel (2 SDRs, 2 different instances of DSD+) this morning and the first voice activity just appeared. It's definitely encrypted but as Forts noted it's not the typical DSD+detectable encryption.

2021/03/19 11:14:49 Freq=166.500000 DCC=7 Group call; TG=651 RID=2510 Slot=1 3s

2021/03/19 11:14:49 Freq=169.290000 DCC=7 Group call; TG=651 RID=2510 Slot=1 3s

 

[gary123]

Its a shame DSD does not output the ENC byte to say if its basic, DES, AES.

Q could it be TierIII. I highly doubt another mode such as pDMR.

If someone could get a visual on the radios they are using that would really help.

I finally heard them transmit this afternoon and I am seeing this as well. Not showing up as encrypted but sure sounds like it. I also saw RID 760 come up too.

I thought it usually does say it is Basic or Enchanced Privacy.. If it would be Tier 3 though wouldn't it be showing up as such? As far as I am seeing it's showing as just regular DMR.

I'm focused on the HSR and the Brantford systems lately but perhaps next week I will start to record this system on my SDS100.
I listened to it a few times in the fall on a 436 and I think but don't quote me on this but it sounded encrypted.

I shall report back next week with my discoveries.

ATC I love your Cubs Avatar. In addition to preparing for my Strat-O-Matic team draft, I'm re-reading a book about the Cubs 2016 season.
And in this league there were two ATC dudes in the league. There used to be two but initials JT who always wore shorts left, leaving only initials JC.

Both knew you and I remember once you told me that you knew them.

Current DSD+ Fastlane will differentiate between the privacy types on DMR (BP/RC4/AES).

There are 3rd party encryption options available, they may be using one of those for whatever reason.

 

[gary123]

I am hoping someone will get a look at the radios. If they are not Moto that will tell a lot as well.
