Many thanks to SWLing Post contributor Carlos Latuff, who writes:
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.
Update: Shanghai Meteorological Bureau for (today) October 9, 2025
One of these days, Carlos, I’m going to have to try this for myself.
I love the “pointing hands”!
Cheers, Jock
Don’t think twice, Jock… do it! Now! I’m absolutely sure you’ll love the experience!
Greetings from Brazil.
We are feeling the effects of Halong at the moment here 70 miles east of the Kamchatka Peninusula. We are due to arrive in Tokyo Tuesday morning, meeting what will then be the remnants of Halong on the way.
It seems to me that this year is being particularly active for typhoons in the Pacific, John.
Greetings from Brazil.
These radio faxes are very interesting. There should be a photo of the equipment here on this site.

Oliveira, there is dedicated radiofax reception equipment, used on vessels to receive weather charts. However, it is possible to receive these signals with a radio receiver equipped with single-sideband, such as the Xhdata D-808.
Saudações do Brasil.
