Over on the YouTube channel Tech Minds the presenter has uploaded two new RTL-SDR based tutorial videos. The first video gives a bit of background and shows how to decode Morse code with an RTL-SDR. He uses SDR-Console V3 and the Morse code decoder CwGet. With this he's able to decode a few calls from some ham radio operators.

In the second video Tech Minds shows how to decode Weather Fax with the RTL-SDR. Weather faxes are images of weather charts sent over HF frequencies. In the video he uses SDR-Console and SeaTTY to do the decoding and demonstrates reception of an example fax.
