Midland Model 74-102. Manufactured February 1989. I found this in a thrift shop yesterday. It had a 9V battery so I gave the dial a turn, and sure enough, it still works!
I can't justify the cost of a new weather radio, but this guy only ran me four bucks. Now I need to get my hands on a 12 volt barrel jack power supply.
The pin is positive on this guy. I just dug up an old power supply that came with a modem I'm not using anymore out of my box of random electronic whirlydoos. The voltage and polarity are both correct, and the jack fits the port. We're totally in business!
Oh, the wife is gonna hate this thing when there's a tornado in town at 3AM. Here's the alert tone. Check the volume on your headphones first.
