I once did a weekend overnight shift (in December) in a very small town whose AM station pumped out a whopping 54 watts at night. (This was not my regular shift.) To get me to take the shift, the then-PD said that I could just track CDs all the way through if I wanted to. Since we had already been wall-to-wall Christmas on what we now know as "black Friday," I decided to track a reel-to-reel tape of Christmas music. This tape had the wrong type of tones, so we could not use it on our automated FM station, anyway. (I rewound it each hour while the network news was on.) Easiest shift ever for me. I went the whole night without ever cracking the mic on the AM! (Of course, now the station has an FM translator, and they carry syndicated satellite overnight programming, so what I did on my shift there back in the early '90s would not even be necessary anymore.)
