This, along with the WWVB station[0] that makes most of your "atomic" wall clocks work, is an underappreciated national (and international) resource that was almost shut down recently[1] due to budget cuts.
I'm not going to link directly to any of them because of the Hacker News hug of death, but do a web search for "websdr", find a US based or nearby location, and try tuning to either 5000 kHz, 10000 kHz, or 15000 kHz (depending on the time of day - lower frequencies are usually better at night), AM mode, to listen in.
