Yesterday while northbound on the Deerfoot over the Calf Robe, I got a CC bleeding over onto a CFD 800 MHz simplex frequency that's in my scanner (in the 856 MHz range). I get similar bleedover on Stoney next to Spy Hill where the AFRRCS and CMRN towers are. I am thinking maybe there might be something worth looking at in Bonnybrook or Alyth. If my cards come up right tomorrow I'll give the area a drive-through (I was busy today Christmas shopping elsewhere).
There are licenses in IC records (TAFL) for some of the freqs, in the various tunnels and maintenance shops, but then again there are licenses for the existing system freqs in those areas too, so that's not much of a telltale sign.
