We're out of hibernation after 39c3 and back to planning! ❄️

Currently, we are discussing the further progress of the project, including whether and how we could provide a purchasable pager kit.
Thank you all for your great interest and patience. We will try to come back with more concrete information as soon as possible!

Meanwile, here is our recap of 39c3 and Norddeutscher Funktag: https://signalspielplatz.de/Blog.html

Looking forward to the ChaosPager Talk by @signalspielplatz

Btw: If you have a SDR (RTL-SDR or HackRF) and a USB A to C adapter you can demodulate POCSAG with the SDRAngel App.

I want to add such a feature to my RF Analyzer app for next Congress (https://github.com/demantz/RFAnalyzer)

[39c3] Chaospager - How to construct an Open Pager System for c3

At 38c3, we conducted an experiment to test out our self-built POCSAG Pager infrastructure. Together with DL0TUH and CERT, we are now working on an open pager solution leveraging well-known components in the maker commmunity (e.g. ESP32, SX1262) t...

We have a callbook for tests. And the first pager meme has reached us 😄
thx @maltepoeggel_de for ''RIC & Morty"

Send more memes, and come say hi!

ChaosPager: Teste unsere Pager‑Infrastruktur!

Du findest Pager toll? Dich interessiert, wie man eine kritische Infrastruktur konzipiert, oder du möchtest solche Systeme am 39C3 kennenlernen? Du suchst einen einfachen Einstieg in die Welt des Amateurfunks? Wir vom Assembly Signalspielplatz entwickeln und betreiben in Kooperation mit dem CERT und der Funkergruppe DL0TUH eine Pagerinfrastruktur, die in Zukunft die Einsatzkräfte des CERTs alarmieren soll. Um diese zu erpoben, würden wir uns über viele Testaussendungen von euch freuen! Nachrichten empfangen Wir betreiben unser System auf 439.9875MHz. Folgende RICs stellen wir für euch bereit: RIC Beschreibung 8 Sender-ID (DL0TUH) 1111 Info 1122 Tests 1140 Event-Info Saal Zero 1141 Event-Info Saal One 1142 Event-Info Saal Ground 1143 Event-Info Saal Fuse 1150 Event-Info alle Säle 2504 Datum & Zeit (Skyper) Bitte beachtet, dass wir im Betrieb nichts garantieren können, da wir selbst Tests für unser Projekt durchführen müssen.
