consider yourself lucky just got my brand new 2009 airnav box up and running and it does not pick up any aircraft at all apart from network aircraft and i live less than 2 mles from doncaster EGCN (disapointingly not recognised by airnav although its been open a few years) not sure wether to bin it or spend more money on coax, couplers and whatever else to see if i can get it to work, ps am not a radio wizz but any helpful pointers appreciated
