Welcome to the Signalspielplatz. We are all about signals (radio) and signals (railway). We play with POCSAG, Meshtastic, railway technology (e.g. PLC) and Modacom, among others.

To test how well POCSAG works in buildings, we brought our POCSAG transmitter with us. You are of course welcome to use this as an amateur radio operator. You are not an amateur radio operator? - No problem. We will explain the transmitter to you and you will have the opportunity to test it with our training call sign afterwards. We are also happy to receive reception reports. We will of course confirm these with a QSL card directly at the assembly.

You want something tactile as a signal? That is no problem for us either. We have signals as hardware. The signalling control for the railway signals is developed right now.

And what came actually before GSM? We have a lot of tinkering, reversing and reviving the data radio of the 90s - at least the hardware.
