Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares the following illustrated radio listening report of a recent CNR broadcast and radiofax transmissions from both Japan and South Korea meteorological agencies.

Carlos’ goal is to vividly illustrate the broadcaster’s message in his own unique artistic style and is not a reflection of his own beliefs or those of the SWLing Post. His objective is for his artwork to add historical context and put a visual with the news, reporting, and broadcast content:

Japan Meteorological Agency Radiofax (August 24, 2025)

Hurricane Erin from NOAA radiofax via USCG Honolulu

Many thanks to SWLing Post contributor Carlos Latuff, who shares the following radiofax images and notes:

Hurricane Erin, featured on NOAA’s 24/48 tropical surface forecast, received a radiofax last night in Porto Alegre, Brazil, from the USCG radio station in Honolulu, Hawaii (16135 kHz USB).

Curiously, the signal from the USCG radio station in Honolulu reached Porto Alegre MUCH better than the signal from the USCG radio station in Boston. Honolulu is approximately 12,744 km away from Porto Alegre, while Boston is 8,307 km.

Here in Porto Alegre, for the past two days, it’s been difficult to receive radiofax from the USCG radio station in Boston. Weak signal, short radio propagation window and lots of noise. Only today morning I was able to receive NOAA chart featuring Cat 4 Hurricane Erin.
