CBC Toronto signed off 740 in 1999. It ended with a loop of a female voice telling people which FM signals to tune to. Have that on tape somewhere, it’s not labeled so it will be hard to find.

The frequency returned from the same facility in December of 2000 as “Primetime Radio, AM740”

A lot of the music mix on WDLS’ “Vacation Station” can be heard on it’s sister stations 1350 WPDR Portage (Soon to have a big FM translator in Baraboo) and on WRDB in Reedsburg. It’s owner, Magnum Broadcasting (now Magnum.Media) relied mostly on Jones-Westwood One programming until about 5-6 years ago when they took everything local.
