Show HN: Web App Uses RTL-SDR to Align HDTV Antenna

27 points by robotastic 3mo ago

I was sick of losing the Telemundo signal during World Cup, so I built a Web App that uses a local RTL-SDR dongle to analyze the HDTV signal and help you point your antenna... GOAAALLLL!

Lol. Full circle. RTL-SDR was originally the DVB-T tuner, hacked for SDR, to become.. a DVB-T tuner. Great job!

    ATSC. Technically orginal RTL tuners handled both (in really thin gateware, which is why the chip was so hackable for SDR, you just turned its debug mode and it would stream its IQ values).
