FoxSniffer is a VHF/UHF (100-225 & 275-450MHz) receiver with tight filters and switchable attenuation for fox hunting / RDF. It can detect any modulation (AM, FM, CW, etc) and so is not limited to hunting any particular type of transmitter.
The core circuit is designed around a custom SDR (Tayloe Detector circuit) and an RP2354 microcontroller making it easy to improve and modify.
See AI6YM.radio/foxsniffer for details or to purchase an assembled FoxSniffer.
