#### Inspiring interest in radio communications

SDRplay provide a “software defined radio” (SDR) which turns a Raspberry Pi or PC into a full communications receiver capable of picking up radio signals across the spectrum from long waves to microwaves. All you need is the SDR and a simple antenna which is often just a length of wire. This simple tutorial can help a class pick up signals for themselves: https://youtu.be/JvP8t8aPmRw and this inspiring video shows how a class can pick up actual pictures from the International Space Station (first the class can practice on other signals and when they are ready, they can time their listening for when the ISS is transmitting pictures and passing overhead. See: https://youtu.be/vRwH0FlH9MA Potentially SDRplay can lend a school an RSP1A, or they can be bought with educational discount by emailing jon.hudson@sdrplay.com (SDRplay co-founder)
