Default Vertex Digitral radios

Our client just got Vertex radios. I understand they are digital. Going into service tomorrow.
So the question, are Vertex DMR, P25 or??
Where do I search to find the freqs?
There is a repeater, if that helps.

Something useful, like a model number would help. Knowing which band split would also help too. With out that we can not answer either of your questions.

Vertex does both DMR(Tier 2) and conventional P25. Only on VHF and UHF though. Vertex has no offerings in either 700MHz or 800MHz.

Thread moved since the Vertex isn't a scanner.

No, I am asking if my DMR capable Whistler will be able to find and monitor these radios. Totally scanner related.

Sorry if you misunderstood my post.

Look the license up on the FCC website. Find the emissions designator and you will know whether it's DMR or P25

I will see the radios when I get into work tomorrow. What I am really curious about is the range. They had to install a repeater with an antenna on the roof in order to cover all the dead spots in the building (it is like a giant Faraday Cage).

Sp wondering how far away I might receive it. It is a City agency that owns the radios and they have licenses on hundreds of freqs.

SMDH... you ask questions that we canít answer because you do not provide ANY useful information. So with out any information I will provide a useless answer:

It depends.

It depends on the band, how much power the repeater transmits, how much loss in the duplexer, how much loss in the feedline, gain of the antenna, type of antenna, electrical tilt of the antenna, HAAT, height of the building, what the terrain is like where this building is, type of tree cover.

Not trying to beat you up, but nowhere in your original post did you saying anything about a Whistler scanner. So based on what you asked it was moved to an appropriate forum.

And even now you are asking questions specific to these radios and/or system.

My guess on how far you will be able to receive them is probably at least 100 feet.

WOW, they put the repeater antenna on top of the faraday cage, that should work like crap.

The radios are from "BearCom" and are marked "BC250D" (No, not Uniden bearcats)

They are 7 channel, and using Spectrum Sweeper they are DMR. I was only able to check the secondary Freq (can't keep it keyed up on main band LOL) and it comes back as 463 Mhz. The only other info is that in order to transmit you have to key up and wait for a "chirp". I always associated that with trunking, but I doubt that could be true since the first two channels hit the repeater, the other 5 are "point to point". Doubtful they could be hitting a trunked system anyplace.

And yes, the building is like a Faraday cage. Partly because it is a super secure facility. Verizon phones can't get service there, and it took a repeater and three different antennas until they could get reception throughout the building.

That "chirp" could be just a simple TPT (Talk Permit Tone). Available on most radios for use with or without a repeater or trunking system. Or it could be MDC.

Based on the info sheet here:

http://bearcom.com/wp-content/upload...DSpecSheet.pdf

It has an emissions designation of 7K60FXE which would mean it's a MOTOTRBO compatible radio. In other words, it's going to be DMR.
