Radio at Makerspace – POCSAG Paging MB7PNE

MB7PNE is the POCSAG Paging transmitter

Pager technology, once the bane of anyone on call, has been reinvented by the amateur community in a distributed system which can be used to push alerts and other useful messages in the form of DAPNET (Decentralised Amateur Paging Network).

Hardware

MB7PNE is largely the same as the transmitter described on the DAPNET wiki here. The notable differences being the use of a Motorola GM900 instead of a GM1200, the addition of hardware to remotely disable the radio and a very over-engineered software/infrastructure deployment.

Full details of just how over-engineered this transmitter is are available here.

Pagers

This page on the DAPNET wiki has a good overview of compatible pagers that will work with DAPNET. SDR based options and the protocol spec are also easy to find for homebrew solutions.

The wiki also details how to program Skyper and non-Skyper pagers to receive pages both directed to you and containing rubric news.

Data

MB7PNE is in the uk-en-northeast and uk-all transmitter groups on DAPNET, so anything targeting those groups will be transmitted.

MB7PNE is built and managed by Maker Space members.
