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...

ARRL Call to Action in Defense of Part 97 Allocations in the 3 and 5 GHz Bands
The FCC WT Docket 19-348 and WT Docket 19-138 will severely curtail growth of one of the newest and most effective means for Amateurs to support emergency communications. Existing installations will be severely curtailed or, with no reasonable alternatives, be forced to cease operations. Thousands of hams have built or are in the process of constructing high-speed data networks in the 3 & 5 GHz ham microwave allocations.
Background
AREDN (Amateur Radio Emergency Data Network) was an outgrowth of the ARRL working group on High-Speed Multimedia (HSMM). It has evolved over the past 10-12 years from its first implementation by Broadband Hamnet (BBHN). Over the years the AREDN Project has developed software support for nearly 70 commercial wireless routers---moving them from their Part 15 allocation into adjacent Part 97 allocations in the .9, 2, 3, and 5 GHz bands---providing an inexpensive and easy way for hams to implement high-speed (up to 144 Mbps) data networks in support of Emergency Operations Centers (EOCs), Non-governmental Agencies (NGOs) and first responders. The project has twice been recognized by the league for the significance of its achievements by awarding the Project the ARRL Microwave Development Award in 2014 and 2018.

AREDN Receives Grant from Yasme Foundation
The AREDN Project was recently honored by the Yasme Foundation with the award of a $7000 grant for the purchase of a 20 GHz spectrum analyzer. The analyzer will be used to understand the characteristics of 802.11 protocols in the unique, long-distance mesh, configurations of AREDN implementations. It will also afford us the ability to measure, and perhaps, improve the quality of transmissions emanating from AREDN-supported devices.
The AREDN Project team is grateful to the Yasme Foundation for taking the time to consider its need for a spectrum analyzer. Andre Hansen, K6AH, in speaking for the entire team said, “To be awarded this grant is particularly gratifying for us because it acknowledges the value the AREDN Project affords Amateur Radio.”
The Yasme Foundation is a 501(c)(3) not-for-profit corporation organized to support scientific and educational projects related to amateur radio. Their support includes long distance communication (DXing), the introduction and promotion of amateur radio in developing nations and encouraging youth participation in amateur radio.

AREDN Presentations at SCALE 17X March 10, 2019
There will be two AREDN presentations at the 17th Annual Southern California Linux Expo – SCALE 17X – to be held on March 7-10, 2019 at the Pasadena Convention Center in Pasadena, California, near Los Angeles.
Both presentations will be on Sunday afternoon, March 10 in room 212.
The first talk by Orv Beach, W6BI is titled “The Ham Radio Internet - a Progress Report”. It will start at 15:00 in Room 212.
Orv reports that IP Networking is one of the fastest growing modes in amateur radio. The ham radio internet (lower-case eye) continues to grow in both capabilities and span. Driven by improvements in custom open source software for wireless access points by AREDN (arednmesh.org) and with their support of more equipment from more vendors, it now covers from Santa Barbara to the Mexican border and east at least to the Inland Empire. At any given time, there are more than 300 nodes up and running.
He 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...
Yuma Hamfest 2019
Andre, K6AH, will present an update on the AREDN team's open source software development progress and report on useful tools and techniques to ensure a successful mesh network implementation. His talk "AREDN Project: New developments in software and successful implementations around the Southwestern Division " will be given on Saturday, February 16, 2019 at 11:40 am. Andre will describe new Emcom applications which make the mesh even more usable.
The Yuma Hamfest and ARRL Southwestern Division Convention will be held on Friday and Saturday, February 15 & 16, 2019 at the Yuma County Fairgrounds, 2520 E. 32nd Street, Yuma, AZ 85365. For more information, see the Yuma Hamfest website. For tickets and vendor registrations, see their online registration form.
