drose12,
I'll add those two frequencies now.
Thanks for doing that. (It's 3 frequencies, 118.000, 120.500, 119.70).
Is there a chart available that shows the airspaces?
A little old but still mostly accurate.

Some notes if it helps,
- low altitude airspace extends up to FL280, high altitude is FL290 and above
119.700 - FL290 to FL350
120.500 - FL360 and above
- 119.700 is rarely used as a separate sector, normally 120.500 is used for both, so FL290 and above. However the controller will still simulcast on 119.700 even when the sector is not split and you will be able to hear aircraft on other frequencies via cross-coupling.
- many sectors are combined depending on traffic volume and time of day.
- Winnipeg uses CPDLC quite a bit (high altitude airspace only), so you will not hear a lot of hand offs and some clearances from CPDLC equipped aircraft.
If you're using an SDR setup, and it's not to much trouble, is there any chance you can make the low altitude and high altitude feeds separate ?
Low Altitude
134.400
132.250
118.000
High Altitude
120.500
119.700
124.000
134.175
You wont hear the controller on 124.000 and 134.175 but should get good aircraft reception. A lot of times they are cross-coupled with 120.500 anyway but when they are split it would be handy to have them up.
Thanks again for the great setup !
