Just connect a directional antenna and set the frequency. Gain and attenuation are applied automatically - just turn your antenna and listen to the tone to find a bearing to the transmitter.\u003c\/p\u003e\n\u003cp\u003eI designed the FoxSniffer to handle a wide range of radio direction finding tasks. The receiver is sensitive enough for foxes far away while still handling strong signals with useful feedback. You can stand on top of a 5W fox and the FoxSniffer will still be able to tell you which direction to look. If you've ever been fox hunting with me you know I need that level of help - if I went looking for a real fox it would bite me long before I spotted it.

With open-source hardware and software built around the RP2040 microcontroller (the same chip used in the Raspberry Pi Pico) the PicoFox can be anything you'd like it to be. There's ample CPU, flash, and GPIO available if you want to add features like sensors or interactivity. The transmitter can generate a frequency or phase modulated signal with up to 2.5kHz (data) bandwidth so APRS and most other digital modes are well within the range of possibilities.\u003c\/p\u003e\n\u003cp\u003eShips fully assembled in a beautiful injection molded enclosure.
