How to receive weather satellite images

The easiest way to receive weather satellite images is to check the schedules for the HF stations, and find when they're re-transmitting satellite images.

But, if you want to recieve the images directly from the satellites, here's what you'll need:

Other than the above items, receiving the images is similar to receiving HF weather fax transmissions, except that you have to continuously re-tune the radio, or have it controlled by your computer! Also, a given satellite usually only makes one or two passes overhead each morning and evening. Each pass usually lasts 10 to 15 minutes at the most.
