​ARRL Awards 2018 Microwave Development Award to AREDN Team


​The ARRL announced that The Amateur Radio Emergency Data Network (AREDN) project team was named as recipient of the 2018 ARRL Microwave Development Award for its initiatives to utilize Amateur Radio’s microwave bands. These included extending the network’s high-speed multimedia capabilities from solely 2.4 GHz to 900 MHz, 3 GHz, and 5.8 GHz, and adding 802.11n protocol to improve data throughput. The Board also acknowledged the efforts of the many AREDN implementation groups around the country who are building networks based on this technology and who stand ready to utilize them to serve the needs of their communities in times of disaster.

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."
