Software Defined Radio
What is it?
The Software Defined Radio (SDR) is a compact and inexpensive radio designed to receive radio waves from the antenna and covert them into a usable form for recording them on the computer.
What does it do in the LSTN kit?
After the signal from the antenna passes through the filtered preamp, it reaches the Software Defined Radio which processes the signal and sends it on in digital form to the single board computer.
