Update January 31, 2023

Our HSR boards have been so popular that they fly off our shelves pretty fast.  We continue to place orders with our board manufacturer to keep up with the demand. Sometimes there is a week's delay in shipping products to our customers when we run out of boards.   


Due to the worldwide shortage of Raspberry Pi 3B, and Pi 3b+ boards, we do have a limited supply of Pi3B boards to make complete units.


We offer different purchase options to customers who really want a HotSpotRadio Allstarlink node. 

More Purchase Options

The Allstarlink Node HotSpotRadio arrives ready to plug in and use.  The HotSpotRadio comes with your Allstarlink node number, frequency and CTCSS pre-confuigured and ready to go!  No need to set audio levels or configure your node, its already done for you and arrives plug n play!

Features

HotSpotRadios will be a complete package ready to power up and use.

  • Raspberry Pi3B
