HF Radio: Guide for facilitators and community installers (2022)

by Rhizomatica

"The purpose of this guide is to share the basics of installing a solar-powered HF radio station."

"[It] is an outcome of a number of workshops conducted in 2020 in Puyo and Lago Agrio, Ecuador, by Rhizomatica, together with Kara Solar Foundation and the Confederation of Indigenous Nationalities of the Ecuadorian Amazon (CONFENIAE) in the context of the COVID-19 pandemic. These training workshops were attended by members of the Indigenous nationalities of the Ecuadorian Amazon: Sápara, Shiwiar, Waorani, Kofán, Achuar, Andwa, Shuar, Quijos, Kichwa and Siekopai.

From this effort, which is ongoing as of the publication of this manual, 40 solar-powered shortwave or high frequency (HF) radios have been deployed in different parts of the Ecuadorian Amazon. These radios were installed by Indigenous technicians and local people from beneficiary communities and nationalities, who were trained during three-day in-person workshops in the second half of 2020."

Starlink satellite emissions interfere with #radio #astronomy.

The largest-ever survey of low-frequency radio emissions from satellites has detected emissions from the #Starlink satellite “mega-constellation” across scientifically important low-frequency bands, including some that are protected for radio astronomy by international regulations.

These emissions, which come from onboard electronics and are not intentional transmissions, could mask the weak radio-wave signals that astronomers seek to detect.

As well as being damaging for radio astronomy, the researchers who conducted the survey say their findings highlight the need for new regulations that cover unintended transmissions, not just deliberate ones.

I've been busy as hell this past week.

A lot of people have been asking hard questions about the security of LoRa systems when they hear about mesh radios.

I'm not one to trust the marketing so I and several friends put together two new LoRa tools to help us audit the security claims of LoRa mesh systems!

Woman: WHAT'S NEXT? THE SIMPLE PLEASURE OF A HOT SHOWER?

Man: ACTUALLY, THE PUBLIC WATER SUPPLY IS NOW BEING USED BY AN AI DATA CENTER, SO YOU'RE GONNA HAVE TO KEEP THAT SHORT.
