A few months ago I presented you a wonderful SDR radio project by DawsonJon 101 Things. In short, it is a simple SDR radio with a Raspberry Pi pico.
It has two displays: a small OLED for displaying the menu and frequency and a larger color TFT waterfall display. I made the device on a universal breadboard PCB and built it into a suitable box. The box with the TFT display is from a previous project of mine so I used it for this purpose. In the previously mentioned video you can see the method of making it, as well as a detailed description of the menu, functions and features of this receiver.

Meanwhile, the project is being developed with the support of the community and today's version has significant improvements compared to the first alpha version.
In this video I will present you those improvements in order:
Now let's turn on the receiver to see the difference in some segments compared to the previous project.
The large TFT display with improved waterfall dynamics and a characteristic retro scale is immediately noticeable.
During the video you can notice that the received signal is relatively weak, and the reason for that is that I was currently using a regular long wire antenna because I had a problem with my LOG antenna. For that reason I also used preselector, the making of which you can see in one of my previous videos
And finally a short conclusion. With the new retro-style tuning dial and improved waterfall dynamics, the user interface is now as impressive as the receiver's performance. These visual upgrades, paired with the new noise reduction and calibration features, make this a must-build project for radio enthusiasts.
