Many thanks to SWLing Post contributor, Carlos Latuff, who recently shared a number of Radiofax images of Typhoon Khanun he’s decoded over the past few days–apologies as I’ve been traveling and could not post when received. Carlos writes:
Attached is a satellite image broadcasted today by Japanese meteorological agency via radiofax (7795 kHz USB), and received by me in Porto Alegre, Brazil, at 19h10 UTC.
Even with image quality compromised by the signal, it’s possible to spot powerful typhoon Khanun, approaching Okinawa, with winds of 220 km/h.
Receiver is a Xhdata D-808 with loop antenna, signal decoded by HF Weather Fax app.
