Are We Alone? How GNU Radio Can Help Us Find ET
summary
Breakthrough Listen already publishes 2 PB public spectrograms spanning 1–12 GHz with channel widths down to 3 Hz and runs on the Green Bank Telescope with 20% time on GBT, ingesting hundreds of terabytes of raw voltages per day and reducing to a few hundred gigabytes per hour for analysis on an on-site cluster. The Allen Telescope Array exposes a 42-antenna ATA 1–12 GHz system with USRP N320/N321 hardware, a 200 MHz bandpass per USRP, a 24-antenna switch matrix, 100 TB of storage, and example captures (Voyager carrier) available for GNU Radio pipelines and community follow-up.
