p25

Hey all. What is the most inexpensive radio that is p25 capable?

Hello. I am looking to aquire an nx-5200 to use as a ham radio and to scan my county fire frequency’s. They use a p25 phase 2 ICORRS system. I currently have a Uniden sds100 and it works just fine with the system. I confirmed that some agency’s in the counties use 5200s but they said they are...

Forum users regularly speak to which subsite has the simulcast site controller (prime site), or which site has the ZC (master site / zone core) in an Astro25 trunked system. Are these assertions based on something in the FCC license that I'm not picking up on?

Hello all you radio junkies! Lol Ive had a fair share of scanners in the past from when i was in my teens till now. I love to listen to whats going on around me. Then awhile back everything went encrypted, but i just recently discovered my area has fire rescue back on the scanner radio app so...

I have two Kenwood TK-5710 VHF 50 Watt mobiles forsale. One has a remote head. Both include microphone, speaker, and cables. They were pulled from a working environment about three years ago when our county transitioned to DMR. One was a base station and one was used in a POV. They are in good...

Just for the record, which scanners can receive Simulcast and actually decode it? I have an SDS200 but I'm looking towards a P25 P2 Simulcast handheld.

Hello. I am hoping to set up a portable standalone repeater for some digital modes with MMDVM and some old mobile radios, something I know has been done many times. However, I do not want it to be networked for ease of setup and some other reasons. It will be mainly used temporarily at events...

What would be the CHEAPEST scanner besides a rtl-sdr dongle could get by with to listen to everything in my area? Thanks a lot. My Area My Area

Does anyone know what causes this. notice the bottom of the waterfall, That is normal it's showing the signal and everything is good and then about every minute or so i will see the top part of the waterfall do this. i have played around with the gain and everything else but nothing fixes it...

I have been trying all day to get this to work on a pi 4 i have installed it and deleted it 3 times but i keep getting this same screen. when i first install op25 it will kinda work it just doesn't show the tsbks counting and it won't show the NAC. it starts this when i edit the trunk.tsv and...

This is a project that I've been working on for a long time now on and off. It's nowhere near done and I have a lot left to re-implement but here it goes. The OP25MCH or OP25 Mobile Control Head is an Android app that is written in Python with Kivy that allows you to remotely control an...

I'm seeing these unknown link control messages carried in a contiguous chunk of TDULC messaging on some Phase 1 traffic channels. In both examples, it was immediately following an AES-256 encrypted group call. Within sdrtrunk I'm calling these RADIO REPROGRAM, but I'm not yet certain of the...

Howdy all you much more experienced people with this realm than myself! I've recently been trying to scan local trunked frequencies using the SDR Trunk software on my M2 Macbook Pro with an RTL-SDR dongle. I love this software's ease of integration with Radio Reference, but I've been striking...

Hi, I’ve doubled checked the TGIDs for both the BFD Ch 3 & 4 patches to the P25 system. Ch 1 & 2 works but not 3 or 4. Any thoughts/suggestions?

Selling it to fund my next ham radio purchase. Radio is in excellent working conditions, nothing scratched, rusted or burned out. Radio comes with DC cables and AC adapter. Please note the condition of the AC adapter cable. When I bought it, the previous owner had it terminated in such a way...

Why was P25 phase I decoded with so many artifacts in the audio? this even goes for P25 radios of the 2000s. Was this the first attempt at digital voice decode? Why did it take so long to improve it?

So, lately I've been looking for help with some of the things I'm seeing within Zone 1 and 2 of the FleetNet P25 system here in Ontario. I've been helped by members with things to try etc (big Thanks). I'm Located near Peterborough and should have coverage of the Peterborough, Pontypool...

Hey Everyone, got a bit of a Tech Special today. So I received a Harris P5500 in the mail that seems to have a slight issue. The radio feature menu is showing "SYSGRP#0," where normally it would say SYSGRP#65535. Ive already gone through some troubleshooting steps like upgrading the feature...

Perplexed by the flawed reception of a conventional P25 public service repeater. SDS200 receiving over a ~6.8 mile route with no sizable obstacles. [low-lying hills] No scan priority, weather alert, attenuation or filters employed. Firmware: Main Version 1.23.03 Sub Version 1.03.02 In my...

Hey all, I'm really hoping this doesn't turn into a flame war or anything, I'm just trying to better understand the key differences in implementation. Question I'm aware that companies like Anytone, Hytera, Motorola, etc. offer encryption in their DMR radios, and I know that Anytone and Hytera...
