Using a relatively low-cost receiver and antenna, we record these transmissions for later demodulation using our computer soundcards and dedicated software (Timestep Prosat32).
The advantage of using a mini-disk is that a computer - and particularly, a computer screen - can give out RF interference which will interfere with our very sensitive receivers and will corrupt the resulting image. Recording to mini-disk gives you perfect, interference-free images every time.
