activity on 133.4 in minnesota

[KF8ZR]

I am hearing activity on 133.4 Mhz AM in Maplewood Minnesota.
I am unsure of which airport this is.


Can someone tell me what I am hearing?
Sounds like possibly air to air or directions given over the air.

Are you hearing ATC? Best I can tell, the transmitter is located in Alexandria. It's a high altitude enroute sector for ZMP (Minneapolis ARTCC).

Yeah the ARTCC can be heard fromn hundreds of miles away. Pretty neat I'm in Southern NJ and hear ALL of NY ARTCC and half of Washington ARTCC especially the high altitude frequencies

High Altitude in this case means 24,000 feet and above. 133.40 is Minneapolis Center Sector 11, basically covers the area northwest of Minneapolis. Pull up Flightradar24 and set the altitude filter to 24,000 and above and you can see what you are listening too.
