Description
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!

Could you build this?
Partial The front-end antenna meter UI is simple, but interfacing with RTL-SDR hardware via WebUSB or local daemon to decode ATSC/HDTV signals and calculate real-time SNR requires specialized digital signal processing knowledge.
What it would actually take: The system needs either a local server or WebUSB implementation driving the RTL2832U chip to sample RF spectrum around ATSC carrier frequencies (VHF/UHF). It requires implementing or wrapping DSP algorithms (FFT, pilot signal extraction, constellation analysis) to measure ATSC 8VSB signal power and SNR in real time. DSP and RF engineering expertise are required to convert raw I/Q samples into accurate signal quality and alignment metrics.
