Carlos Uncovers the Mystery Behind a Strange Radiofax from the Japan Meteorological Agency

Many thanks to SWLing Post contributor Carlos Latuff, who writes:

This is the image I received today, October 12th, at 7:10 UTC, in Rio de Janeiro, Brazil, from the Japan Meteorological Agency, via radiofax (13988 kHz). It was supposed to be a satellite image, showing Tropical Storm Nakri (which will become a typhoon in the next few hours). Instead, I received this truncated image. This isn’t a radio transmission/reception error, but rather a problem with the image generation from the Japanese Himawari satellite, something I hadn’t seen before.

This is the information provided by the Japanese TV NHK website.

Many thanks to SWLing Post contributor David Iurescia for sharing the following article about one of my favorite topics, which we’ve covered in the past.

Long before Zoom classrooms or remote-learning platforms existed, Australia was already teaching across the outback via radio. This article from Education Daily explores how the School of the Air began in 1951 using shortwave radio and evolved into one of the world’s most advanced distance education systems—connecting students across half a million square miles.

It’s a brilliant look at how necessity inspired real innovation in broadcasting and education.
