GB7ME – The Rugby 70cms Digital Repeater

The Rugby 70cm digital repeater is an experimental platform, currently as Mk2 – DStar operation. 

The original Mk1 platform went into soak in December 2016 and deployed later with positive behaviour throughout. This ran until summer of 2023.

The Mk1 platform comprises two Motorola GM340 radios within a Eurobase chassis. The controller is an MMDVM modem using an Arduino Due with Atmel AT91SAM3X8E. This and the MMDVM host on a Raspberry Pi are built from source. The Raspberry Pi also does some monitoring tasks such as thermal & network latency.

The Mk2 platform is currently active. An Icom ID-RP4010V providing Dstar coverage to the local area.
