AREDN Release Notes v3.20.3.0 – 27 March 2020


The AREDN team is pleased to announce the general availability of the latest stable release of AREDN firmware. We now fully support 70+ devices from four manufacturers. This diversity of supported equipment enables hams to choose the right gear for a given situation and budget.

AREDN firmware is now based on the most recent stable version of OpenWRT19.07.2 which was released in March 2020. This improvement is significant in that it enables AREDN firmware to benefit from the many bug fixes, security improvements and feature enhancements provided by OpenWRT developers from around the world.

The latest AREDN firmware contains features inherited from the newest OpenWRT upstream release (19.07.2). One important change is the inclusion of a new target (architecture) for the firmware, labelled “ath79”, which is the successor to the existing “ar71xx” targets. OpenWRT explains that their main goal for this target is to bring the code into a form that will allow all devices to run a standard unpatched Linux kernel. This will greatly reduce the amount of customization required and will streamline the firmware development process. As not all supported devices have been migrated to the new “ath79” target, AREDN continues to build firmware for both targets.  You may notice that the AREDN download page has firmware for these two targets, and you should select the latest...

Ham Radio Presentations at SCALE 17X on YouTube


The ham radio presentations from the SCALE 17X conference are now available on YouTube.

The presentations are:
1. Orv Beach, W6BI will detail that growth with emphasis on Southern California, with metrics, maps and graphs.  He'll also cover some of the more significant network events, including the ability to stream video of recent brush fires from networked mountaintop webcams to YouTube.

2. Paul Wilkinson, K6IG talks about “Raspberry Pi + HAM Radio = Inexpensive repeater system”. With little effort a very powerful HAM repeater can be made with a Raspberry Pi, two HAM radios, and an internet connection. Some additional, yet inexpensive, hardware is required.

3. Ben Kuo, AI6YR presents “Linux, Raspberry PI, RTLSDR, LAME, and Open Source: A Recipe For Responding To Natural Disasters”. He covers both the why's and how's of putting together your own Raspberry Pi-based, open source system to help your own local community tap into the power of the crowdsourcing and social media emergency management.

QSO Today Interviews Andre K6AH


Eric Guth, 4Z1UG / WA6IGR writes "Andre Hansen, K6AH, and his team of open source developers have taken amateur radio mesh networking to a new level with AREDN, that allows commercial low cost WIFI routers and access points to be used to build out local and regional broadband networks in the amateur bands above 2 GHz. Andre and I discuss this technology and its possibilities for the amateur radio community in this QSO Today."

Listen to the QSO Today podcast here.

"QSO Today is a podcast about amateur radio also known as ham radio.  Every week, I interview a leader, a mover and shaker, in the amateur radio world.  Many of the technologies that we enjoy today including television and radio, cell phones, computers, and the Internet were born out of the amateur radio experience. Amateur radio was the frontier where hams conducted electronic experiments in order to make that wireless contact around the World."
