tetra

How have people been able to get information from unlistenable and untrackable systems like iDEN, OpenSky, and TETRA? I mean like talkgroup, LCN/LSNs, and site info? I thought you couldn't listen to or track them properly unless you have a radio connected to that specific system. Some examples...

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...

welcome :giggle: I am your new friend in this beautiful forum I want you to help me deal with devices Selex PUMA T3 Plus DM/380-430 Anyone who has experience dealing with this device, please contact me, thank you

Looks like US agencies aren't the only ones Motorola attempts to wring every cent out of... Will this set a precedent and will more government customers follow suit? Maybe Motorola will "get the message" and make changes, or will they just bulldoze ahead like they always have...

Is it possible to use a Tetra radio to listen to someone else's Tetra trunking network? I hear this network through the tetra's plugin RTL-SDR. What are the minimum parameters for this? (Freq, MCC, MNC, GSSI -Is that it?)

Hi, I have a Motorola Cleartone CM5000 and I would like to activate the DMO repeater mode on it. This is done with a PIN code entered in a special menu. Motorola does not want to generate a code for me because the device is EoL, so they offer me a new one. These are the example codes for...

TETRA PDU LIKE THIS RAW DATA '0x009725E25645D900A00' How can I get the longitude and latitude from the data packet, it is best to use C code to describe, thank you in advance.

Users. In the UK, specifically West Midlands, has anyone got a working clear Tetra frequency they want to share? Secondly, are Ambo’s and The Highways Agency clear and if so, where in the band might they be. Looking forward to the replies, forum Police please note, I’m not interested in any...

Are there any programs available which can reliably decode TETRA control channel data? There's a couple systems I'd like to work on getting into the database.

Questions for all the tetra folks on here. -Are Motorola tetra radios able to transmit in analog conventional or are they strictly trunking? -My understanding is that with a special SIM card the radio allows DMO mode. Is that the case or can any radio be allowed into DMO as long as it's...

Hello. I'am new in Tetra System,and I recently bought Motorola MTP8500Ex brand new and without battery. I've successfully turn it on with my APX1000 Battery with some cable jumped into connector. Now I wanna ask something with the USB Cable, Why this device shows "Accessory not supported" when...

Pretty much the title says it all , how would one go about scanning when there’s no scanning community that shares findings? Ill walk you through the spectrum and my setup here and if you can chime in on how people managed before RR database existed i would be grateful. Aside from the scattered...

I'm an EE and was looking for some potential open source or similar projects to contribute to. Because the spec is available online and it's got some cool digital aspects, as well as a few systems in my region, I thought I'd take a look at TETRA (maybe osmocom-tetra or something). I do have one...

Greetings! Today I am releasing an early version of TETRAMonitor SDR# plugin (property of TSSDR) with packet capturing support. I've been testing it last night and it successfuly decoded over 200KB of IPv4 packets with 96.6% success rate (good IPv4/UDP length, good IPv4/UDP checksum). I can...

I've been messing around with SDR# TETRA Demodulator plug-in to see what I could come up with in regards to trunk tracking TETRA. I did this as a stop gap until the big players have come up with something. And in true SDR form, here is the setup. I used 2 instances of SDR# (for CC and VC)...

Hi, today in my DSD+ FL 2.84 a new line appeared. What's this? it is a sign that in the future a tetra decoding function will be implemented?

Hello everybody, I installed a few months ago telive on windows (Index of /data/my-tools/wintelive) , there is some method to listen to only one group at a time? many times on some busier repeaters are unable to listen. Thanks Alessandro

Is there any reason why "TETRA" is not an option for the nationwide trunked system reports? I could be doing something wrong, but I curious to see all the TETRA systems in use in the United States and there was no easy way to do it. Thanks in advance!

Hi everyone, I am using SDRSharp with an Airspy Mini running at 10 MSPS and I am using 64x decimation. I am tuned to 384.250 mHz and am expecting to receive a pulse from a portofone (transceiver) every 4 seconds. I am using an appropriate dipole TETRA antenna (for the frequency of 380.25 mHz)...

Good day gurus. I want to know the exact model of this radio and if it is possible to connect a headset to it. We have a small office and this sucker is too loud. Our set up would be this base radio with possibly a plantronics ptt headset. The problem is that we are clueless as to what hardware...
