Whats that annoying noise in the background (YYZ)?

[...]

Every time I fly on the south east sector between Kingston & Toronto, there's a background 2-tone hi-lo squawk that can only be described as the second most annoying noise in the world, the first being the 'gazzo horn'...

If no one knows what I'm talking about...maybe I'll consider lowering my daily dosage of Ritalin.

Might be the strip printer. Some sectors have them close enough to the controller to be heard.

No...it sounds more like a 2 chime door bell underwater up on full volume thus distorting the speakers.

No specific timing on it going off. Just every minute or so I hear a

GLIMB#%^#$ GLAMMMMMBDzzzz&@*^$%

I know that I may sound nuts but someone else in th ac heard it as well. LO freqs.

Did you try answering the door?

Stop checking your blackberry text messages in the plane birddog. There's plenty of time to monitor the latest TSX numbers once safely on the ground.

Thanks Jonny & Desksgo...You each win a 43" LCD TV for your contribution to this tread. Expect it in 6 to 8 hours. A black van driven by a guy named Guido will be by to drop it off. Make sure you and your next of kin are present.

For all you ATC people, you get a box of fruit & cream filled Skittles candy also delivered by Guido...he'll be @ Nav Canada to make sure 'everyone' gets it.

I've heard it too, so you're not nuts (or maybe we both are)

I have no idea what it is though...

Well, I waited for my TV but nobody came. I even had my whole family here...

For the record, I've heard the noise too. Usually above 10,000' and as high as FL210. The noise tends to start (IIRC) somewhere in the vicinity of YPQ/YCF and is usually gone once we start our descent for LANRK. The best way I can describe the sound is that it sounds like the TTC (Toronto Transic Commission) subway system's first & last door chime tones put together and with squelch/tin sound to it.

It is quite frustrating... If possible, I'll try to get a recording of the sound next time I'm heading that way.

I think its the shift manager....

I'm not sure of the name but i was told that noise was when JAZZ sends messages to dispatch back and forth ... thats the two chimes you hear..

Hmmm...Really? A couple of people PM'd me and told me it maybe 1 of 2 things.

If this 'unit' that is producing all this noise over a closed mic with no one really transmitting, I can only imagine the high amount of RADIATION it is producing to those that are in close proximity to this unit.

Kinda like a Blackberry cell phone near any kind of speakers.

Well always go with the first answer given.

One of your colleagues went out of their way to solve the mystery. It does seem to be the strip printer.

If I worked at Navcan and had to be next to that thing squawking all the time, either I'd marry it, or throw it out the door!!! That printer sounds like a mother in-law; you folks don't get paid enough.

Thanks my 'anonymous Navcanada' person, YOU ROCK!!
