Carlos’ Radiofax portable receiving and recording station.
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:

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.

Thank you for sharing these, Carlos. It’s amazing that with such simple equipment we can track and download weather events and imagery like this. Pretty amazing!
