Make sure you hit the Save box at the bottom. If you switch between the two transmitters, remember to change this figure. For Germany, put 850 in the Frequency shift box or leave it at 800 for UK reception. This is changed through Configure / Operating / Active Modem, select the Other tab on the second row and then the Wax tab below it. If you are receiving signals from Germany then the shift is 850Hz instead of the default 800Hz. If you want to use fldigi to receive WEFAX, you need to do the following: fldigi receiving a WEFAX image from the Northwood transmitter This morning I switched to the Northwood frequency of 4,610.000 kHz and very soon the pictures started rolling in. The 3,855.000 kHz signal seemed about the best for me here. I first started listening on the UK frequencies but heard nothing so I switched over to Germany and over the course of the week, I received a lot of pictures. There are two in Europe that I decided to try listening for, one in the UK at Northwood and the other in Hamburg, Germany. A quick search around and an ask via Twitter pointed me towards this document which lists various transmitting stations around the world.
I soon had it configured correctly and so the next stage was to find what frequency the WEFAX pictures are transmitted on. I use fldigi for operating data contests so I’m very familiar with it.
I know that strictly this isn’t amateur radio in the true sense because these transmissions aren’t within our frequency allocations but it’s still interesting.Īfter very little searching, I discovered that fldigi can receive fax pictures. I’d tried a couple of years ago to receive satellite weather pictures with little success (due to a very poor aerial) and the idea that I can receive weather maps on HF intrigued me. This grabbed my attention because I like maps and I like to see things to do with the weather. A week or so ago I saw a weather fax ( WEFAX) picture someone had posted that they’d captured on HF.
