Hi Boab,
I recommend you start of with an easy to use scanner though one you can still get a good reception from. Bear in mind radio waves transmit in line-of-sight, so you'll need to go somewhere else to listen in if you live in a heavily built up area... also land etc can hamper the reception.
Here's Edinburgh's frequencies:
TOWER: 118.700
APPROACH:
121.200; DIRECTOR: 128.975
GROUND: 121.750
ATIS: 131.350
And you may be able to hear these Scottish control frequencies:
GALLOWAY SECTOR (TMA OUT)
: 124.825
TALLA SECTOR (TMA IN)
: 126.300
SCOTTISH FIS: 119.875
TAY SECTOR (LOW LEVEL)
: 124.500
There is also
Cumbernauld Radio on
120.6 and
Fife Radio on
130.45 but you may not receive them...
Good luck
