Was on my SDR today and I came across a weak DMR transmission at 453.801-ish. The signal became stronger as the afternoon progressed. It appears to be a school bus radio system. Checking through the FCC I found no licenses for a school bus company. I can upload some audio recordings if needed...

Hi everyone I fired up DSD+ and was able to dump a, well at least I think it is, a DMR T3 CC...or could it be some kind of data modem? It is only periodically active, about every 30secs for a few seconds. Slot 2 seems to be silent, but in slot 1 I see data. What do you think...is it a data...

Hi everyone! I'm in proccess of trying my new TRX-1 out an I have a question for all of you. How accurate is DMR detection while using Spectrum Sweeper / Tune Mode? In 80% of cases it won't detect DMR on my device. It stays in FM mode. The signal comes from a DMR Tier II repeater. My TRX-1...

When submitting conventional DMR/MOTOTRBO frequencies, please use the following format for the CC/TG/SL info: CC 1|TG 100|SL 1 The way that field is displayed on the database webpage as three lines is not how we enter them, and it becomes a bit of a mess in the submission. One line with the |...

If radio A (The transmitter) and radio B (The receiver) are occupying slot 1 for a call, what will happen to radio B if radio C keys up at the same time? Will radio B hear both radio A and radio C?? *Assume slot 2 is idle, radios A, B and C have different radio ID and all three radios are in...

Hi all, I'm trying to listen for DMR and P-25 traffic on my local amateur bands, and can't figure out how to do it. I've tried two things: 1. listen for digital chatter with an analog radio, and directly enter that frequency on the SDS. It will sometimes decode the color code and TG but the...

I am interested in using DMR over Itinerant frequencies for our commercial business. Can I license an itinerant frequency for DMR emissions? Can I use a hotspot and push the DMR over the internet to another location (within the state I am licensed for)?

I would like to apologize if this isn't the est place to post about DMR-related questions. I didn't see a dedicated DMR board and this seemed seemed as close as I could find. My question is about DMR radios equipped with GPS for location sharing -- does anyone know of a DMR that can be equipped...

Looking to sell my two whistlers that I have had over the years to take a further dive into the SDR world. What is pictured is what goes with it. The handheld is missing the clip and olive drab insert for the case. The base/mobile is missing the bracket, network cable(for different placement for...

I am looking to build another repeater using the STM32 board. I have one built using two Motorola VRM 850 radios. It works great except I cannot get my Hytera PD782s to work with it. After hours of digging, I came across a thread about how Hyteras don’t work with Motorola’s converted to 403-470...

Hello, I am part of a school club and we currently operate Analog FM and P.25 repeaters, and since many of the club members have DMR-capable radios we wanted to look into setting a DMR repeater as well. We own one of the RepeaterBuilder MMDVM kits, and two Motorola CDM750s to use for RX/TX, I...

If anyone that works (or lives) in the downtown Seattle area then please help me figure out who is on 410.9 Mhz. The problem is that you'll need some old fashioned DF'ing to help with this one since it's DMR and encrypted with RAS. It seemed to start in April 2021. It was very quiet after the...

I have a 2019 Chevy Silverado Crew Cab and will be putting in two small mobiles " President McKinley and Anytone 578 DMR radio. Normally I would mount in Havis at the center seat. Problem is sometimes I have to have that center seat. So can't have a permanent mount , figuring a mount for both...

Hi In New Zealand I have found a couple of repeaters in my area that transmit DMR. This is a strange setup as its only 1 frequency with a DMR TIER 3 format. It has 1 frequency and when its not in use it has no data flow, its just dead. When a user keys up the repeater it activates a TGID 9999...

Good Afternoon, Does anyone know of any companies in NC, specifically around Wilmington, that lease time slots on DMR repeaters? If so would somebody be able to provide the name of companies that provide this sort of service. I've done a lot of research on this but have been unable to identify...

Hi, so I have a BCD996P2 and I can find the frequency for the DMR system in my country, but I can't find anywhere that has a list of talk group ID's. Is it possible to setup a DMR system without putting in talk group ID's and just catch anything that goes over that DMR frequency? I'm using...
