DVB-T could technically carry clock, weather forecasts, and alerts as text data feeds. What needs to be done to link WEA Wireless Emergency Alerts with HD radio data streams? WX radio could possibly embed a data channel? If it doesn't already for e.g. accessible captioning? DVB-T: https://en.wikipedia.org/wiki/DVB-T https://en.wikipedia.org/wiki/DVB-T : > This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing (COFDM or OFDM) modulation. From https://www.rtl-sdr.com/about-rtl-sdr/ https://www.rtl-sdr.com/about-rtl-sdr/ : > The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. [...] > Over the years since its discovery RTL-SDR has become extremely popular and has democratized access to the radio spectrum. Now anyone including hobbyists on a budget can access the radio spectrum. It's worth noting that this sort of SDR capability would have cost hundreds or even thousands of dollars just a few years ago. The RTL-SDR is also sometimes referred to as RTL2832U, DVB-T SDR, DVB-T dongle, RTL dongle, or the "cheap software defined radio" From https://www.reddit.com/r/RTLSDR/comments/6nsnqy/comment/dkbv4nn/ https://www.reddit.com/r/RTLSDR/comments/6nsnqy/comment/dkbv... : > [You need an upconverter to receive the time from the WWV shortwave clock station on 2.5, 5, 10, 15, and 20 MHz] http://www.nooelec.com/store/ham-it-up.html http://www.nooelec.com/store/ham-it-up.html From https://news.ycombinator.com/item?id=37712506 https://news.ycombinator.com/item?id=37712506 : > TIL there's a regular heartbeat in the quantum foam; [...] https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.043041 https://journals.aps.org/prresearch/abstract/10.1103/PhysRev...
