I talked to a VE3 the other night and the subject came up. He said he thought the shartwave relay that simulcasts with CFRB, Toronto been discontinued, along with other shortwave transmitters that relayed certain Canadian MW broadcasters. I haven't heard them for a long time. They used to come in here very well during the daytime during the winter months.
I ran upon this web site, and from what I read, they have been having transmitter problems, and about a year ago a landscaping company knocked down their antenna, a 50' vertical mast. Supposedly a new transmitter and antenna have been ordered and they should be back on the air soon.
CFRX has been on the air since 1937, and runs 1000 watts 24/7. The original homebrew transmitter was replaced by a plate-modulated Bauer unit in 1983. They used to run a two-mast directional array, but later changed to the single 50' vertical mast, located at the CFRB antenna site, as shown in the photo.
