Sorry if this frequency has been posted elsewhere. I have looked at Jay911 frequency list for ATCO, but could not see this frequency, nor 138.950 or 138.940. Did a search of the Canada Forums and this only hit one thread from Ontario. I have heard a sporadic carrier, no voice or noise, on the freqeuncy of 138.945 for the past couple of months. It is so annoying that I have locked it out of some scanners. Because I generally listen in the evening, I cannot say if it is there during the day. Looking at the Spectrum Direct [now that it is online again], I see this frequency is listed to most of the electrical companies, generally outside of Calgary. And I have heard this carrier throughout southeast and southwest Calgary. Am I, or did I miss something here?
