@hikhvar #Tetra scheint seit ~2025 IP sprechen zu können und nicht mehr auf SDH angewiesen zu sein (PDF Seite 21):

"Seit dem 1. Juli
2022 setzte das Einzelprojekt Migration der BDBOS diesen Auftrag um. In einem ersten Schritt fand die Umrüstung der
bestehenden Netzinfrastrukturen des Digitalfunks BOS auf das sogenannte Internet Protocol statt. [...] Ein wesentliches Vorhaben dieser Moder-
nisierung war und ist die Umstellung der
Zugangstechnik von E1-basierten Leitun-
gen auf IP-basierte Technologien."

@hikhvar ich weiß jetzt nicht, wie #Tetra aktuell konfiguriert ist, aber theoretisch gab's / gibt's noch nen Rückfall-Modus wodurch du irgendwie noch in TMO funken kannst, wenn die Basisstation ihren Uplink verliert. - Aber keine Ahnung ob du ne neue Basis-Station auch gleich im Rückfall starten lassen kannst.

Anyway, teardown pics. SRP1000. Almost identical to the Simoco SRP01 I have. Very similar to the SRM1000 too. Motorola PHW amplifier. 68k main CPU. ADSP-2183 DSP. Some custom part from Atmel (AT55534). An unknown part from "WM" (I expect this is some sort of I/Q mod/demod).

New one. Simoco SRP1000. Been missing one of these from the collection for a while and saw one come up on eBay. Basically an SRM1000 in an extremely large, heavy but allegedly “handportable” enclosure. Probably not much chance of programming this one but still a nice bit of history to own. Weighs about 700g, apparently 3W Tx. Might have a go at powering it up this evening and do a teardown too. #tetra #hamradio

Das #ETSI will ne Breitband Ergänzung zu #TETRA Bündelfunk als "European Critical Communications System" #EUCCS für #BOS Funk sepezifizieren.

Technisch wohl nahe an LTE und 5G

Made a thing this weekend. Lots of broken stuff, but it's enough to model what happens with different ALOHA parameters.

There's an incomplete list of caveats in the README.

Mit dem #SXceiver Board für den Raspi 4 (5) kann man seine eigene kleine #Amateurfunk #Tetra #BTS laufen lassen.
ca. 1mW kommen aus dem sendefähigen #SDR
Als PA (wenn nötig) kommt eigentlich nur ein Class A Verstärker in betracht.
Die 10€ billig PAs aus der Bucht funtionieren auch, das sollte man aber nicht auf einem Hochhaus
aufbauen: da kommt auf den direkten Nachbarkanälen noch zu viel Leistung raus...
Das Projekt (Bluestation) findet man auf Github.
Es gibt mehrere Telegram Kanäle auf denen man auf dem laufenden bleibt.
Aktuell ist man bei Version 0.58x
Aber einbuchen, sprechen, SDS mit Bestätigung, sowohl innerhalb der BTS als auch
übers Netz (Brandmeister, als Hotspot anmelden) funktionieren schon einwandfrei.

Anyone playing with tetra-bluestation - quick one... When an MS sends U-SETUP and the BS responds D-CALL-PROCEEDING, I always see 3x retransmissions of the BL-ADATA segment containing the D-CALL-PROCEEDING PDU (MS never appears to ack it). Wondering if anyone else sees that behaviour.

Einige Einsatzkräfte bei uns im #DRK haben nach Videos gefragt, mit denen sie sich ihr Wissen zum #Digitalfunk auch nach gewisser Zeit Pause wieder auffrischen können. Dazu sind ein paar Videos entstanden, die zeigen, wie man das Motorola #MXP600 (und MTP6000) bedient.

Die Videos gibt es auf der Webseite des DRK-Ortsverein Ravensburg unter godrk.de/digitalfunk.

Weitere Videos sind bereits geplant und werden bei Gelegenheit hochgeladen.

Now that's some properly old trash.
Two Nokia TMR400's with clear firmware, from the first civilian TETRA network ever, the HELENET system of the Helsinki municipal power company.
Strictly 410 - 430 MHz and the devices predate DMO, so they only work in TMO mode with infra.
Until TETRA-BlueStation these were worth essentially nothing to anyone who's not a radio collector.
And even then you could barely give them away.

The handset is some UHF band Nokia made MPT1327 radio.

Wishlist for 2026:

* gr-soapy gets transmit timestamp support

* Phil Greenland's #ADALM-Pluto timestamping work gets upstreamed in the firmware, FPGA image, IIO and SoapyPlutoSDR

* I can finally do #DMR and maybe even #TETRA with a Pluto

Alright. Here's another #tetra teardown!

Bit of a mystery model this time. I can tell you it's made by Greek company OTE. OTE's TETRA stuff has since been merged into/sold to Selex. Unsure where this device would have been used. Internals indicate it's 380-400MHz band so possibly public safety? I found some discussion on forums of handsets that look like these being used by Gas/Oil firm Gazprom but nothing really definitive.

Either way, this terminal dates around 1999-2001, making it a pretty early TETRA MS. The various COLLAUDO (Italian - test/inspection/trial) labels kinda indicate this was already in the Selex era.

Not a hope in heck for cables or software for this one, so it's a purely ornamental addition to the collection I'm afraid!

On arrival it also showed signs of battery leakage... gloves on for this one :blobfox0_0:

A new FOSS TETRA stack enters the scene: TETRA-BlueStation
https://github.com/MidnightBlueLabs/tetra-bluestation

You cannot communicate through it yet, but terminals attach to it.
So the actual physical layer works and is standards compliant enough for the handsets to attach without crashing.
An exciting development!

Btw it is written in Rust.

Mmm lots of curious looking MXP600s from China on eBay. Kiiinda tempted but also lots of red flags (why are so many of them shown with the board out? Lol. Also the serial number on the boards don’t match the one on the back casing) https://www.ebay.com/itm/356906371259 #tetra

Managed to sneak in some TETRA tinkering today.

Got one of the 25 year old Simoco/Sepura SRM1000s booting, programmed and talking.

Wow, these things are unfriendly to use and implement such a minimal feature set. The programming software is absolute arse, even by 90s standards (but, pleasantly it does still work on Windows 10).

I get the distinct feeling they are software-descendants of some earlier analog Simoco gear that was repurposed to quickly jump on the 90s TETRA hype train.

Bit delayed (work has been hectic sorry) but here's some more TETRA teardowns... That's why you follow me... right?

Simoco SRP01 (1999).

Can't find that much about this one, but I know it was developed by https://en.wikipedia.org/wiki/Sepura as their first handportable TETRA radio after their acquisition of Philips' PMR arm, originally http://www.pyemuseum.org/.

Simoco went on to become Sepura in 2002 and are still one of the largest suppliers of TETRA equipment globally.

This one is 380-400MHz (TT) band, but I believe a TZ band version existed (410-430MHz). Some of the writing on this one might indicate that it's an early development unit.
