Tuesday morning, I pile David into the car to take him to daycare. I turn on the digital radio in the Prius and start trying to find a good station. Thing is, suddenly, all of the stations are the same! NPR, WTMX, WRXT, even WBBM, it’s all WGN. And the station’s running some kind of emergency broadcast test which doesn’t seem to be going well. Weird, and worrisome — obviously, the radio is busted. But when I tried the same stations later that morning, it’s all good again, all the stations are where they are supposed to be.

Here’s what happened.

At least the radio is ok.
