Getting Started

To get started you will need 5 things.

  • RaspberryPi 2, 3 or 4
  • A radio
  • RIM or URI
  • New England GMRS image file
  • A New England GMRS Node number

To get your node number you will have to file out our online form or send an email to support@newenglandgmrs.com, in you email include the following:

  • First and last name
  • Address
  • Phone number
  • eMail Address
  • GMRS Call Sign

I know Pi’s are difficult to get right now, but if you can get a Pi 3 or 4, either will work with the New England GMRS image 1.x

As a note, if you don’t want to build you own, you can purchase a radio hat to plug into your GPIO of your Pi 3 or Pi 4. You can purchase the hat from hotspotradios.com.

For a radio, I like the Motorola CDM series. I will talk about the CDM 1250 but the 750 or 1550 will be the same. Other radios will also work, it is just a matter of cabling the radio to the Pi.

For the CDM’s repeater-builder have a nice cable which works nicely.

The RIM-Maxtrac would be for a node, single radio, the RIM-Maxtrac-RM would be for a repeater with a separate transmitter and receiver. The RIM-Maxtrac-RM would be used as your repeater controller.

GMRSLive Getting Started
GMRSLive RIM for Motolrola

The GMRSLive Image you can download from the GMRSLive website.

Above is a picture of the RIM installed on the CDM radio. This is a view from the top of the radio. Notice the extra 2 pins on the left and right of the RIM. The radio has a 20 pin accessory port where the RIM is 16 pins.

Above is the Accessory assignments needed for the RIM and the New England GMRS Linking Software.

Once you have your radio connected to your Raspberry PI go to Software Setup.
