Review on 🛩️ Enhanced ADS-B USB Receiver: AirNav RadarBox FlightStick with Filter, Amplifier, and ESD Protection by Patrick Burton

I bought this stick to replace the RTL-SDR dongle. I thought the built in filter would perform better but it doesn't. Using it with a Pi Zero W with PiAware has reduced the number of observed flights significantly (from 1800 per day to around 200). Maybe I have a bad block or something as it heats up too. The RTL-SDR also gets hot, but at least it has a metal housing that acts as a heat sink. You can see in the attached image when I've used the AirNav FlightStick versus the RTL-SDR dongle and it feels like day and night.
