Programming an extra scanner for aircraft. I have my local airport and one a little further away. Other than the approach/departure freqs for BOSTON and NEW YORK (Kennedy) are there any MAIN long haul frequencies planes use whilst traversing the northeastern US? I am between NY and Boston (in RI). Unfortunately, the radio (BC700a) only has 20 memory channels! But I like the radio and figured I would use it strictly for aircraft. So I want to program it efficiently. I did a search on the air band but there are so many freqs being used, and I cant identify them.
