I'm hearing this on 9990 KHZ at 2212 UTC, but the voice announcement is distorted. Nothing on the other multiples. I have never heard a CHU harmonic either, including the obsessive shortwave years from 1981-1989! Thanks for the tip Chris S!
From 2215 UTC, I am no longer hearing it. Still nothing on 6660 KHZ.
Thanks Chris...I checked out CHU on 3330 KHZ while the 9990 harmonic was on, and the signal was a real powerhouse! I like the way the S-meter bounces for each beep. It was beeping up to S9+10 even with the 10db attenuation switch on( I have to do that otherwise I get daytime overload from a local AM station.)
