Weather has always been a fascinating subject to the English and can sometimes seem to be the sole topic of conversation. Aside from operating your own weather station (which I don't) there is still a lot of interesting data available, including APT images transmitted by the NOAA Polar Orbiting Satellites. Receiving and producing these images is relatively inexpensive by using a. RIGsat receiver which is available in kit form. This, in conjunction with a special aerial, allows reception of the NOAA satellite passes, which occur several times each day. Chigwell is indicated on the images by the yellow cross. How is it done? The RX2 receiver is under the control of a PC program called WXTOIMAGE. This program calculates when the satellites will go past and then selects the appropriate satellite channel on the RX2. Audible radio signals from the RX2 are sent to the PC's soundcard which WXTOIMAGE then decodes into an image. The technology behind this is very similar to a normal FAX machine, which builds images line by line. Simple but very effective.
