DuraNode Simplex 70cm or 2m FM Node kit for AllStar. Photo show this kit as it comes.
This RF hat kit is to enable you to build a Raspberry Pi hosted AllStar RF Node using the AllStarlink network.
AllStarLink is a network of Amateur Radio repeaters, remote base stations and home nodes accessible to each other via Voice over Internet Protocol (VoIP). AllStarLink runs on a dedicated computer (including the Raspberry Pi) that you host at your home or repeater site. It is based on the open source Asterisk PBX running the app_rpt application. App_rpt makes Asterisk a powerful system capable of controlling one or more radios. It provides linking of these radio “nodes” to other systems of similar construction anywhere in the world via VoIP.
The DuraNode is similar to the traditional “hotspot” in that it runs on a Raspberry Pi with an RF hat, and is connected to the AllStarlink network via the internet. The only difference is that the hat uses an FM radio chip, hence no need for a digital radio.
Any FM transceiver with CTCSS that operates in the ham bands can access the node.
DuraNode Simplex FM Node RF Hat kit:
This is a ham construction kit designed by VK4NGA that implements a Raspberry Pi hosted AllStar RF Node. This RF hat kit is to suit the Raspberry Pi 3B/3B+ or 4B series.
Assembly Skill Level: Intermediate – only 2 solder joints required on the bottom of the Raspberry Pi board, plus PCB to Raspberry Pi assembly.
Computer Skill Level: Advanced – SSH ACCESS IS HOW YOU CONFIGURE THE NODE. Also the node has to be connected via Ethernet for initial configuration setup.
You’ll also need a Micro SD card reader to write the Hamvoip software (which is a free download) to your Micro SD card.
The VK4NGA designed/manufactured AllStar RF FM DuraNode hat – is fully assembled, no soldering needed on the hat. The RF hat Is fully tested and it comes pre programmed with operating frequency and CTCSS of 441.250 91.5 CTCSS. This can be changed by you via SSH access.
Cable with JST connector to connect the hat to the Raspberry Pi – goes between the PCB’s and is soldered to the underside of the Pi.
*What you’ll need to supply:
A Raspberry Pi 3B/3B+ or 4B 1gb
A Heatsink for the Raspberry Pi processor.
A Ferrite filter for the PSU – optional – depending if your PSU has a noise/hum issue.
A quality class 10 Micro SD card, 16 or 32GB
A 240v 2amp power supply
The kit comes with complete with build instructions – sent to you via email.
