Meshtastic London !
It seems that Meshtastic is really taking off in South East London with a cluster of nodes appearing between Greenwich and Croydon.
It’s caught the attention of G1HIG and 2E0ULA along with quite a few others in the area as you can see from the screenshot !
Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!

I have it on good authority that if you connect a piece of wire to pin 4 of the gpio connector (length of wire determined by frequency of course) your Pi can transmit.
This Github link will take you to the software and the video in the previous post shows you how to install and run it on a Raspberry Pi
Have fun !
🙂
