trunking

Hello. I am doing some scanning in East Lansing, MI, and have come across a frequency: 851.475 to 851.4875 MHz. It is not always 100% duty cycle, and sounds like some sort of digital audio format, but not one that is familiar to me. It is a strong signal like a repeater output. Additionally...

I have recently moved in Georgia to an area that is surrounded by what RR says are DMR TRBO systems. I have a MD390 that is “DMR” and claims it can handle DMR. One of two particular places I’ve attempted to listen to are Jenkins County and Jefferson County. I have attempted in the MD390 to add...

Does anybody else near or in Allegan County hear what sounds like static clipping in at the beginning and end of each transmission like analog? I mainly hear it from dispatcher units, It almost sounds like a cross-patch. So is it just my radio or is something going on with our system and their...

On the topic of trunking; what would be the cheapest form of trunking? Let's say you want a 3-channel system. Which ideal would be cheaper than the other, DMR or LTR? Or even a networked DMR repeater system. Let's set this up: we will put DMR trunked (insert any of the available options), DMR...

Does anyone know how the inputs for trunked repeaters work? Because I really struggle with this. So this will be a pretty loaded question but I'll ask anyway. 1. Input Frequencies - Setup When setting up a system for the first time, is there a ratio to how many outputs = input frequencies...

Hello, I'm a new user. I've previously owned an analog scanner and used it to listen to emergency channels before they went encrypted many years back. I decided to get back into it and ordered the Noelec RTL-SDR v5 from Amazon. I understand you ideally need two for trunking, but I wanted to see...

Can anybody educate me on these systems more than the wikis show? Like the process of building these systems, managing, the required amount of frequencies to function (input and output), control channels, modes, and systems that could work with it, pseudo trunking, and more? The reason I ask is...

Hey Guys, does anybody tried to virtualize Motorola Trunking Controller like Smartnet, CPX2000, MTC etc. ? The Controller is Sparc Hardware with Solaris 6. So virtualization could be possible with Qemu. However, I fail because of the network interface that a real controller has. Has anyone...

Apparently Motorola has digital voice capabilities on their old trunking systems, what kind of digital voice was it since DMR didn't come out until 2005 and these systems have existed since I think the 80s to early 90s? But I just want to know what digital voice was used on those systems.

Bonsoir tout le monde. Après des moments épuisants et difficiles au cours des deux dernières années et de nombreux voyages dans le monde, je recommence enfin à travailler sur la mise à jour des bases de données dans les régions de la Côte-Nord et du Labrador Ouest. Je prévois faire un voyage de...

I don't think anyone has asked this before. But if were wanted to join a trunking system, how could I locate the owner/company of it and what would I need to do to join one. Along with other questions like; what are the main requirements that I need to meet, how frequent are the charges if used...

I have no idea how to program in talk groups on a trunked system, I can't seem to find anything on how to except for whistler radios. I want to listen to police, fire, ems, etc. how can learn these trunked system?

New to scanner life. Was wondering if I’m doing something wrong. Phillips County in Montana has police/fire frequencies on the basic county look up. But I noticed on the Phillips Co trunking system they have frequencies there too. I programmed the trunking side as well BUT I’m getting...

Hello all, I recently picked up a Unity XG-100 and have been building a mission plan for both trunked and conventional systems in my local area. I have both Sacramento's (SRRCS) and Placer's (PIRCS) P25 networks programmed in, and Sacramento's system is working very well. However, the Placer...

Hello All, Got a TRX-1 and got the P25 Phase 1 System I am using loaded in. Sounds good but often during broadcasts it drops for a fraction of a second and comes back in. I have squelch turned all the way to the left. Signal shows full strength... In EZ-SCAN - Should I adjust anything like...

Trade-offs: price -vs- headache factor (SDR dongles -vs- a real scanner radio). There is a lot of talk about hooking up multiple SDR dongles into hubs, using multiple power supplies, gobs of cabling, antenna splitters, with software configuration nightmares, etc. So my question is, how many...

I have an 800MHz P25 Simulcast site nearby and I was deciding if a directional antenna would be a good idea for my stationary scanner. It would make sense for improving Control Channel and Alternate Control Channel's signal, but if I'm not mistaken, the P25 radios don't talk back through the...

Howdy All, I recently took over Development for Trunk Player and I am happy to announce myself (@maxwellDPS) and @NebraskaCoder are bringing life back to the project! Development is in progress This will be a complete rewrite of Trunk Player, all from scratch! The new version will be all API...

Can anyone tell me how to work with this kind of control channel? I've tried sets on MOT, P25 and DMR but none of them worked. 👇🏽 Control Channel

Hello reader, I am trying to set up my SW1040 to scan Utah County's system, and am having no luck, I'm attempting to scan "Fire 1,2,3,and 4" but it wont work, here's what I've done so far 1. Changed from EDACS to DEC 2. Made new system for utah county and added Utah County Simulcast (turned...
