Much of the system and frequency information I have programmed into these units came from the extensive database at RadioReference. The rest came from my own personal research and discovery/analysis of local systems. Anything that wasn’t in the RadioReference database when I found it is in there now.
Once the radios have received and processed the signals, they’re fed into ProScan, which is running on a Windows PC. Everything picked up by my receivers is recorded and sorted based on system and, where applicable, by individual radio ID.
The PC is on a hardwired Ethernet connection to my 250/250 fiber gateway. Everything is on an uninterruptible power supply (UPS), which should run the entire setup for around an hour if I lose power. If it looks like a power outage is going to outlast my UPS, I have a 10 kW backup generator.
As far as this website goes, it’s running on a LAMP stack. Ubuntu 24.04.1 LTS, Apache 2.4.58, mySQL 8.0.41, and PHP 8.3.6. Audio stream is via Icecast version 2.4.99.3.
I wrote a good bit of custom code for the frontend and backend both, primarily PHP and JavaScript.
