Nobody has figured out what the Ranchlands Hum is.
The CBC article probably means "transmit mode." I bet they have a security guard or a whacker nearby who has a cheapo reflashed Baofeng radio.
Aren't some garage door openers also 315MHz? Maybe one got stuck on?
Lol I apparently didn't read the article too well. Well a car starter stuck on transmit mode could explain the somewhat intermittant occurance for us, the old people who moved in two houses ago though have fairly newer cars, they don't appear to be the type to install stuff on their own. But maybe if I can catch them I will ask if they have any electronics in the garage etc. Like I said I know in the summer they had an audio visual company there installing stuff for a few days.
