I'm building a series of SDR units. My plan is to have custom built software that can sweep and scan a large bandwidth over a MHz to GHz range. Automatic decoders and classifiers with an automatic tag and marking system. Built-in standard demodulator such as AM/FM, usb, LSB, dmr, p25 and other digital Radio Systems. Aprs, GPS receiver. This is all built on top of a Raspberry Pi4 system with a 7 inch touch screen LCD. I have a lime SDR Mini for both transmit and receive.
I decided to make this a postable project on hackaday. As mentioned in the description this is a portable SDR unit that I'm going to be using to scan for signals of various types. I uploaded a bunch of progress photos in the gallery.
I'm using openscad for the case layout and Design. I've gone 9 revisions and I've 3d printed at least one half of the case from 5. I've made various revisions at each 3D printed stage and it has been a great tool on an overall design.
I added five buttons along with a rotary controller to the front panel. The left side has a power button and usb-c power charging connector. As far as the software goes, my plan is to write some original code gluing together many other decoding and demodulation software packages all into one user interface.
Most of the SDR that I've seen can run a wide variety of Open Source SDR software. What is going to set this project apart is the use of custom software that allows a user to easily navigate through multiple decoder and demodulator applications easily and automatically. It is focused on the principles of scanning, sweeping, detecting energies, extracting signal parameters, determining the mode, demodulating, decoding and classifying. In addition my plan is to have future versions support Direction finding and geolocation of signals.
This device can act as a push to talk radio. I'm also thinking about putting in LORA mesh radio.
