Hi 7/9
I do not have a that particular scanner, but it is very easy to listen into aircraft and ATSU's (eg ATC).
All communications are on AM. Basically you need to select the frequency you are interested in and make sure AM is selected. You will find that comms back and forth between the ATSU and a/c are on the same frequency.
Some scanners are able to listen to more than one frequency at the same time, so you many be able to tune into both - but you will have to consult the manual.
As radio transmissions only work in straight lines and are distorted by buildings etc, you may not be able to receive the Tower from were you are - even though you are only 7 miles away - just a warning!
Hope this 'elps
