Our repeaters and gateways use a variety of radios in their construction including Motorola GM340, GM350, Tait 2000, and Tait TM8110. The repeater controllers are based on Raspberry Pi's running the HamVOIP version of Allstar. Our controllers contain extras including remote control,  temperature monitoring and fan control, voltage monitoring, controller status etc. A lot of this data is saved to SQL databases

Allstar is a method of controlling and connecting FM radios and repeaters to each other. It is a very flexible system that can be controlled by custom-written scripts.
