Good way to find out something cool or good way to get myself shot?

Yes

More the cool part though as those stations are pretty old.

Most of them are Cold War relics, so you might hear some degradation in the track by now. Some of them are just throw-off decoys in case of the russians coming, and some of them might have been relays in the old Emergency Broadcast System. If the EBS was to have been fired off, the numbers would have stopped, and the attention signal you just heard......
