Title: CHU 6660 kHz
Post by: ChrisSmolinski on November 09, 2015, 1753 UTC
I'm curious if anyone else can pick up the second harmonic of CHU's 3330 kHz transmission on 6660. I am presently hearing it (1750z), although it is quite weak, as usual.  Using USB mode helps.
You might have to try at various times of the day to hear it. 
I get best reception during late morning to early afternoon.

Nothing here. Very strong on it's assigned freq, but not a peep on the harmonic, 2215z

I have it weak @ 2340 on 6660.  I can't hear any announcements, but I hear the time pips.

Old thread but this is happening again today. CHU harmonic on 6660 KHz, best in USB, some QRM from a close-in data mode.

12:30 UTC 20 JULY 2021 - Nothing heard from my location. I am +/- 345 km / 215 miles from the transmitter site.

The QRM referred to is from an HFDL frequency, 6661.0 kHz USB.

Initially at 2340z I heard nothing.

After some listening I started to hear just the time pips every once in a while. 2345-2350z

At 2351z the time pips are more regular and stronger now.

23:55 UTC - Still nothing for me. I even tried some WebSDRs in and around the Pittsburgh area with no luck.

Separate from the reference to Revelation 13:18, pointed out by Kandi, I'm intrigued that Chris has posted before about hearing harmonics of 3330 on 6660 9990 and 13320 khz. Will be looking for those. Thanks for sharing.

I’m hearing it!! 0040utc 2021/09/31.  Weak, but it’s there.. 6.66Hz

00:50 UTC 01 SEP 2021 - Still nothing heard from my location. I am +/- 345 km / 215 miles from the transmitter site. Must be specific to a geographical region.

02:30 UTC 02 OCT 2021 - It is finally my turn to hear the harmonic --- pips, time data and voice announcements. The harmonic is also clearly visible on the waterfall. I managed to intercept it while decoding HFDL data on 6661.0 kHz. I am located +/- 345 km / 215 miles West of the CHU transmitter site.

Let 'em know. CHU accepts reception reports, plus apparently it will even send a QSL card. Mailing address and email here:

I've sent them reception reports for 6660 and other harmonics. Their engineer claims it's impossible for me to hear them, and my receiver is broken.  :P

Should have mailed him back with a shack photo, then asked all of them? :D

I would say forward the report to IC, and perhaps CRTC specifically, but *good luck* assuming their own internal government radio enforcement practices resemble their amateur radio enforcement practices.

I am picking up the harmonic here also at 2234z. Fairly strong. My rx must be broken to.

Okay, I was curious. I am about 1000 miles from the CHU transmitter site.

There are couple of intermittent utes or similar on frequency, but sure enough, the time interval pips are there as well as I type this reply. I have listened long enough to hear multiple minute interval beeps, too.

Not even using a SDR here. Just my Kenwood R-2000 and the 31' vertical at the moment.

Solar activity is doing very strange things these days.

Check out my post on picking up WRMI on 49890.0 kHz AM, 28 Sept 2021

And no, it's not a typo: 49 MHz, plus I am nowhere near Florida and WRMI's transmitter - LOL

I will try to remember to take a look at WRMIs signal via SDR.
