Awesome!

I'm still noticing which sounds like frequencies being stepped on. Could it be that one scanner is interfering with another one?


The issue is a high-power paging transmitter which is likely very close to the receiver location.  I will work with the feeder to get him an appropriate filter that should eliminate the issue.  

That is the only issue I am hearing.

I am also hearing the receiver being desensitized by some other transmitters, and some resulting crosstalk.

Ahhh ok.. wicked! I wouldn't be surprised if the transmitter is right on top of the apartment building the feeder is in!

That is a common location for cell sites and paging transmitters.  smiley  Last time I was in that part of Toronto I noticed *quite* a few.

That is very likely. I don't see any on my immediate building but as I'm also surrounded by major highways it is very possible. The powergrid corridor may not be helping things either as that runs between me and right next to the airport (see attached image - The corridor is highlighted in red and I'm between it and the airport.

I am surprised at some of the weak CZYZ transmissions and am trying to figure out whether it is receiver desensitization or just weak signals.  Are some of those CZYZ main transmitters located somewhere other than Pearson?

I checked on the Canair site and all the frequency transmitters being monitored are at Pearson. Quite strange considering the Twr/App/Dep feed doesn't have the same weakness.

The CZYZ West Satellite frequency is wrongly stated as 119.3 on the Canada feeds page.  It is in fact 128.275.  I believe the transmitter for West Satellite is in Hamilton and the transmitter for Hamilton Sector is at Waterloo (CYKF).  That could be the reason for weak signal if receiver is in Toronto.  I'll try to confirm this.

mmmm....I used the 119.3 West transmitter that is located at Pearson Airport. At least according to http://www.canairradio.com/yyz.html

And yes the antenna is located in Toronto (about 2km south east of 24L)

Curious if anyone has noted any improvement with this issue? I've been listening to my own feed quite a bit and I don't seem be hearing this interference anymore. Not sure if it's because I've moved it all to a new server or if it's just a fluke.

I really wish I could get the Toronto Centre feed to be better quality from my balcony. Currently using a Diamond D-130J (25-1300MHz) antenna. Would something restricted to just Airband offer any advantage, given that I'm so close to the airport/transmitters?

I'm hoping that some new townhouses are not going to block my great view of the airport and towers Tongue
