Set up a dedicated FT8 monitoring station using Pi Zero 2W + RTL-SDR v4 + WSJT-X for automated band monitoring and spotting. Surprisingly good performance on 20m/40m - decoding 50-80 stations simultaneously during peak hours.

Running headless with custom Python scripts for PSK Reporter uploads and local database logging. CPU usage averages 60-70% during heavy FT8 activity.

• RTL-SDR V4: 14.074 MHz ±3kHz window
• Modified WSJT-X for scripted operation
• PostgreSQL for contact logging
• Nginx for web dashboard

Considering adding 15m/17m monitoring. Anyone running multi-band FT8 decode on Pi hardware?

Impressive setup! For multi-band, consider using multiple RTL-SDR dongles rather than trying to span wider bandwidth - the v4 performs much better in narrow windows. What's your antenna setup feeding the RTL-SDR?

I'm running similar on Pi 4 with great results. For multiple bands, check out the RTL-SDR-Blog's multiplexer - lets you feed one antenna to multiple dongles with proper isolation. Your PostgreSQL approach is smart for long-term trending.

New to this - how difficult is the WSJT-X modification for automated operation? I'd love to set up something similar but haven't done much Pi programming. Is there a GitHub repo or documentation available?
