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.

Typhoon Halong in three radiofax received this morning in Rio de Janeiro:

-Japan Meteorological Agency
(13988 kHz)

-Korea Meteorological Administration
(13570 kHz)

-Shanghai Meteorological Bureau
(12382 kHz)

Note: I added the little hand to make it easier to locate the typhoon on the charts.
Among the three, the one with the strongest signal was the Shanghai radio station, even being 18,235 km away from Rio de Janeiro and I’m in a densely urbanized area.
