Although it may seem as simple as swapping a radio to enable a way to listen to encrypted traffic it just isn't possible.
Sure, it may work for a while until someone notices that it is missing but really how practical is that?

If it's smartnet system the radio must affiliate to operate. It ...

Just to comment for the "encrypt it all now" crowd:

Encryption will solve nothing. All it does is keep the casual hobbyist out. I guarantee you that you could have the highest form of encryption on the planet in your PD radio's and a terrorist or professional criminal could be listening to you talk ...

I've been looking for them also, can you send a copy my way? I intend to use them for designing decals for 2 1:18 scale models that I have.

Thanks!

OOOooooorrrrrrrrrrrrrrrrrrrrr you could search. All those questions have been answered many many many times here and somewhat on the main site.

Well, I tried that and there's plenty of good info but I didn't see any that answered my questions.

Tell you what - if someone would like to share info ...

OK, I've finally had time to go over to my buddies house and pick these up. Busy coupla weeks... anyhoo I have 3 questions for you radio gurus.

1. Is there a place I can find the PROM's to plug into the bottom - the units did not come with any.

2. Is there a way to program these myself or must a ...

I like it! It's very clean looking - not like some weather wacker's car. The lights are just enough - not overkill like some. Nicely done!

I think my ears are burning. ;-)

Yes, that's me. I have a Whelen 9642 'Edge' series with the MGM02 Smart Arrow Messenger board on the backside. The cop-car in the photos at the top of this thread has, as others have already pointed out, a non-Whelen display that was bolted on as a separate ...

An update -

Well, these are infact -10's but here's the interesting thing: There are 2 25 pin connectors on the bottom. One is female and is labeled "Radio" and one is male and is labeled "I/O".

Now my question is, if the RF transceiver is connected to the unit, what is the RADIO port for? My ...

BTW, The -11 does not have a socket under the trapdoor, everything is soldered to the board.

He said there's an empty socket. I guess I'll have to see for myself tonight when I go over there, but it sounds like a -10 from what you said. Bummer.

Oh well. Time to start the weekend ...

Much of that information comes from NCIC and regardless of what you may believe the FCC rules say about monitoring of radio systems - there are VERY strict rules about distribution of NCIC information. If the agency you are monitoring ever found out about it - they would be REQUIRED to report the ...

there might be only one little problem if you want to reprogram a prom: PROM stands for Programmable Read Only Memory. so it's not eraseable aka you can not REload it. hence you will most likely have to buy a new prom and program it for your terminal. and every time you want to change params you ...

Todd,
That's correct - if you flip the unit over with the keyboard in your lap, there's a snap in cover with 3 latches. That's where the prom lives ( it would be just to the right of the FCC ID plate). I'm pretty sure the 9100-11 are programmable without burning a prom as there's nothing socketed ...

We upkept MDT9100-10's for the police here for a couple years, but it was just swap & ship to Vancouver, so I'm no guru. I do seem to recall however that the system ID & some other parameters were blown into a large PROM, it wasn't a keyboard thing. You could manually set the frequencies & the ...

I will doing the same thing, but with FD dispatch messages for a Museum Display. The RF portion will be completely bypassed. The stored messges will be on a Linux based PC. Basically sent every few seconds from a batch of text ...

Here it is: I have 2 MDT 9100-10's enroute to me as I type this. I'm wondering if anyone has successfully hacked one of these to monitor a local MDT system. The one I'm mostly interested in uses these exact terminals on the RD/LAP 9600 BPS protocol.

Here's what I'm thinking.. if I can trick this ...

I just inherited 2 of these puppies, complete with radios. Woo hoo for me.

As my nick suggests, I am a radio scanning nut. Playing with the real thing is something new for me, so if my newbie questions are bothersome, I apologize.

With that out of the way, is there any kind of test mode I can put ...
