I would like to introduce you to a small project I am working on. I think that Simon's software is currently one of the most complete and I really appreciate the effort but I have always found it a bit difficult to manage the controls (in SDR software in general) through the keyboard and mouse (maybe due to the "nostalgia" of physical controls)
My main idea was to be able to operate as similar as possible to a "real" receiver/transceiver, being able to have the software minimized (in the background) and have the focus of the PC on another software/task while being able to control the "radio" in a totally "independent" way from the PC.
All the operation is based (and limited) on the cat TS-2000 protocol that the software implements. I'm sure there are things that many people would like to see implemented but may not be possible through these cat commands (they would require a real API), in any case, any comments or suggestions will be welcome (that's the purpose of this post)
The following features are currently supported:
Dual VFO
Digital smeter
Volume
Current band indicator
Passband Filter Graph / info
The rotary encoder allows you to modify the frequency (VFO) and volume depending on whether the TUNE/VOLUME option is active on the keypad
You can change VFOs, copy between VFOs, modify the frequency jump increment (hz), change the VFO mode (modulation)
The idea is to also support the modification of the squelch value (not yet implemented in SDR Radio but Simon has already taken note of the suggestion) and allow you to modify the filter values (increasing/decreasing low/high cut or bandwidth or through static presets, as in SDR Radio itself)
The only hardware required at the moment is an esp32 microcontroller, an ILI9488 LCD, a rotary encoder and 8 keys/pushbuttons, although I might consider involving "extra" rotary encoders in the future to control things like volume/squelch or filter.
The development of the project is a bit slow since I only dedicate some free time to it, but I hope to soon have a stable version with the minimum of features that allow it to be used.
Finally, the project page (no spam intended):

And now, finally, what most people want to see, the "real" state through some screenshots of the project (the hardware implementation as you can see is very rudimentary since the main thing right now is the software)
