I have been interested in shortwave listening and especially ham radio since my childhood. Some familiy members were hams and I had an early fascination for polar radio operators like Ernst Krenkel. During the early 1990's I have been a SWL and DARC member, but lost interest in the hobby because of antenna problems. Sep 17, 2018 · Many short wave radios but not all will do wefax frequencies, but I found no radio other then the PL680/880 that did the navtex and also even the wefax signal strength is poor on even a Tecsun pl606. Does anyone know a simple cheep radio that could be hooked up to an audio port that could receive on the relevant frequencies as a first step.

How Do I Decode a Weather Facsimile (WEFAX) Off of my Shortwave? Posted on October 23, 2014 While I suppose it could be a case of weak Google-fu, my searches for info on how to decode weather facsimiles off of the shortwave turns up a whole bunch of not much.
WEFAX is an analog mode for transmitting monochrome images. It was the predecessor to slow-scan television (SSTV). Prior to the advent of the commercial telephone line “fax” machine, it was known, more traditionally, by the term “radio facsimile”.
Feb 24, 2017 · A 1691 MHz down converter and a small dish antenna are required to receive WEFAX. The WEFAX images received are cut into 800 by 800 pixel sections and annotated. The 800 lines of an image each take 250 ms to transmit; hence a whole picture takes about three and a half minutes to receive.
