I have just bought a scanner (uniden UBC72XLT). I do not really have any idea how to use it. I have read the manual several times, quite throughly to. but i can't seem to understand it. All i want to do is listen in at my local airport (Christchurch International Airport New Zealand) to whats going on. i have got all the frequinces that i want and need. but i just do not no how to programme them into the scanner. Any tips or how to programme in the frequinces would be much appriciated or is there somewhere, where could i get it tuned or something?
