Has anyone else noticed some outfit has started transmitting telemetry (or similar data) on LADD-1? I thought it was just a setting on my 7360, but all my radios with LADD-1 are receiving the bursts. It is not constant, but data bursts happen every so often it is fairly annoying when the receive tone is disabled. Are you even allowed to transmit data/MDC on open public channels? It seems that company's now are getting so lazy that they won't even talk with IC to get their own frequency, let alone know anything about the spectrum.

Yes, I have heard that noise for months on there and one time truckers were asked politely to leave the channel as it is used by public safety within the city. It sounds a lot like intermittent Motorola control channel noise, but sounds also like possibly some type of encryption method.

I don't normally tune in to the LAD channels because hearing lonely truckers jaw about how the "f'n four-wheelers" are ruining the roads is not high on my priority list, but I'll see what I can hear this morning.

The days of 154.1 being used for public safety in Calgary area are long gone as far as I know - the use was a voice pager back when voice pagers were a thing, before the alpha pagers that were recently retired were in use.

An "intermittent control channel" sound is often a herald of a certain type of MotoTRBO trunking system. IIRC, it signifies a "rest channel".

Heard nothing on my drive in from 8x22 through to 16thxDeerfoot.

Anyone got a sample they can post?

I don't know the acronym definition, but all the references I can find to it on Industry Canada's site (IC manages the Canadian radio spectrum) refers to it as LAD with only one D.

Typically it is used by trucking and oilfield users in the area of western Alberta and eastern British Columbia. It's also apparently used quite a bit by the people made famous in the TV show Ice Road Truckers, though whether or not it's legal to use it in NWT and Nunavut I don't know.

Here around Calgary, where we literally meet the prairies to the mountains and have logging, oilfield, and other truck traffic going in every direction of the compass 24/7, the channels have been co-opted by pretty much every trucking company doing business, from local couriers to trans-continental freight and LTL carriers. LAD 1 has become the CB 19 of Alberta. What's more, if you search the frequency or term on Google, you'll find pages where 4x4 users and campers have declared it "the official 4x4 channel" or something ignorant like that.

On the main topic of "interference" here - I wonder if some chucklehead has got hold of a DMR radio and programmed the LAD channels into it?

Yup. All those limitations... Yet I see LAD 1-4 used all over the place in northern AB for resource road radio control... By big name oil companies.

Only LAD 1 and 4 are legally allowed to be used in Alberta with in the limits outlined above... LAD 2 is not allowed anywhere in Alberta, yet I can think of a couple of radio controlled roads that use LAD 2. Side note, 158.940MHz is used on a few repeaters by fire departments... They have had major issues with truckers... PL masks the problem, but does not eliminate it,

I forget which LAD channel it was, but I was at an interoperability conference in Montana a few years ago and overheard some admins from MT PSSB (I think) talking about interference on a specific frequency, which I recognized as one of the LAD channels, and mentioned so. IIRC it is an input on one of their trunking sites and they get all sorts of issues with unauthorized use of the LAD channels south of 49.

A number of years ago, I read an IC posting that truckers using 154.1 along the Canadian/US border near Vancouver were interfering with a public safety frequency in Washington. On a recent trip out to Vancouver I still heard a lot of truckers using 154.1. I believe Kay1n32008 recently posted about digital on this frequency around Drayton Valley or somewhere up north. I generally don't have 154.1 programmed unless I am driving outside of Calgary so can't comment on and data or digital. I have posted a couple of times about digital on the FRS frequencies. With all sorts of radios being easily available from eBay and China, we will probably see more of these popping up on every VHF/UHF frequency.

In the past year or so I have heard what sounds like Canadian truckers using several LAD and Alberta wide channels here in Texas. Also on frequencies like 152.05 and 173.0 that don't appear to be in IC's band plan.

A local fire department uses 154.100MHz as a fireground channel in Ontario and it's not unusual to hear truckers on it.

Correct. It was/is used by WSP in Washington state. I have heard DMR on LAD 1 west of Fox Creek in the Kaybob area. Recently I started working at the NWRP in Sturgen County and i habe heard DMR on LAD 1 in that area as well.

Even 15-20 years ago I heard lots of activity on LAD-1 in the exclusion areas of BC.
