Broadcaster: Radio Canada International Interval Signal Series 1970's

Date of recording: Circa 1970s

Frequency: 9.625 MHz

Reception location: Ancaster, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 or Realistic DX-150A and a longwire antenna

Notes: Back in the early 1970s, Radio Canada International ran a very popular interval signal series on their SWL Digest program. This was hopefully to help DXer's identify that sought after station. I recall recording a few of these programs, and while going over one of my old cassette tapes recently, I came across a segment where they were presenting a number of African interval signals. Subsequently, I have uncovered five additional segments, or at least, portions of them. As these were originally recorded with an open mike to the speaker of the receiver, some room noise (voices) may be detected, as well as small amounts of unedited material near the ends of some of the segments. These were recorded at Ancaster, Ontario, Canada, likely on 9625 kHz.
