DMR Pirates

Post by Werthers »

Has anybody noticed strange DMR I.D's pop up on your radio or people using other peoples DMR I.D's?

They say there are no pirates or keyers on DMR?

I haven't noticed personally, but you can use whatever DMR ID you want to. ID spoofing will always be an issue, but then you could equally just start saying someone else's callsign in regular voice too. The only way around it would be to enforce a one-time programmable IMEI-style ID which is burned into the firmware and cannot be changed. Then you'd need a centralised registry of those too.

You can't use whatever ID you want on DMR. You have to register your callsign and an ID is assigned to you.
If someone else is using your ID, either you gave it to them or they've used you callsign to check online what your ID is. The other possibility is you've sold a DMR radio and forgot to reset it and left your ID and callsign on the software.

I've been using DMR id 1234 since last year. Granted, I can't use most repeaters, but simplex is fine.

Technically you can use whatever ID you want. I could look up anyone's callsign, find their DMR ID and type it into my radio's programming software. There is nothing stopping me from doing that (except on brandmeister if they enable the callsign security feature). I believe this is what the person you replied to was trying to say - that you can use whichever ID you want to and there is nothing checking it.

I don't use DMR but know the basics. I didn't know about the security feature on the BM system.
Like i said if the person knew you callsign and looked up online, they could pirate using your ID.

As previously pointed out in prev posts, there's nothing to stop any joker or lowlife from using someone else's ID or callsign on air simplex.

It's only when you use any route RoiP or through a repeater that's linked you need to use a legit ID, borrowed or legit issued to you.

There are a few test ID's that allow connection via connected routes, but that's frowned upon apparently even when just used to do legit hotspot setup tests and not further used until you get your own.

But the fact that borrowed ID's can be used reflects that from the outset nobody saw fit to consider that the level of managed reuse of the existing DMR ID method would be inadequate by default. So, from the outset and magnified by the fact that many sources of DMR kit don't do what radio outlets should do - only supply to verified or evidence presented proof of a valid PMR license or Ham license.

That would at least, using the existing RadioID DMR reg structure as it stands, keep out the not determined and casual unlicensed abusers a minority at worst.

However, it also shows another practical flaw in both how RadioID issued ID 'requirement' is presented and understood.

The only ID that's mandatory on UK Ham Radio transmission is your call sign and operation suffix, as defined in your license terms/schedule.

The RadioID additional issue ID requirement isn't currently legally mandatory for any DMR DV use, just it's not a mandatory requirement in law to have a registered D-STAR or C4FM/YSF ID.

They only serve as a indication that you are a registered ham operator, who has presented currently licensed status at the TIME of registration (so, like an MOT cert, it reflects a status at the time only). This being necessary to help comply with only allowing verified Ham operators to RF gateway link to other ham ops who pick up by RF or IP only - meeting the 'must communicate with licensed operators only' legal operating requirement. Beyond that, outside of linked operations, there's no enforceable requirement for a valid DMR ID.

So, realistically, your third-party registered ID should made part of the data held by OFCOM on your license profile and only checkable by licensees (if you provide the link means, you really should be a licensee in practice even if not running RF linked at your end).

Clearly an ESN/IMEI style unique hard device ID, logged against your callsign and RadioID or other for DSTAR/C4FM should be required, so the entered ID on your set plus it's hard ID would create a unique countersign that networks use to verifiy both valid use of valid equipment by current licencees.

After all, the IMEI and device barring control system works well in Cellular services - so similar logic would make perfect sense to licensed requirement status usage of LMR and ham usage of digital modes.

What we have, instead, is a trust based but usually effectively managed ID system governed by toothless tigers who actually have no legislated authority at all.

I'm all for the honour amongst gents trust we extend in ham radio, but when toothless tiger nobodies get to define your legit ID availability or status, something's gone seriously pear shaped with the whole thing.
