PEPYSCOPE: A Simple Panadapter for HF Radios using RTL-SDR Direct Sampling

Over on GitHub user mcogoni (Marco/IS0KYB) has recently released a new program called Pepyscope. Pepyscope is a simple and fast panadapter application that is designed to be used with direct sampling capable RTL-SDR's such as our RTL-SDR Blog V3 units. Like other panadapters you simply connect the IF output from the hardware HF radio into the input of the RTL-SDR. Then Pepyscope gives you a waterfall display that helps users to easily visualize the spectrum.

Pepyscope is open source and runs on Linux PCs. So far Marco has tested Pepyscope with a KENWOOD TS-180S (single conversion with IF at 8.83 MHz) and an RTL-SDR v3. He has also uploaded a demonstration video on YouTube.

    Why do you need a specific software that will only show you the waterfall?
    Why not using SDRsharp?
    I am probably missing something here.

      It’s probably possible to install this onto a low power computing device, like a Pi 3, or even something cheaper and weaker. Then combine it with an LCD screen and you have a standalone panadapter.
