Thanks for reply.
Where i stay both GLA and EDI would be very easy to operate from. A lot of scope for setting up the radio gear in nearby fields, but still close enough to the airport etc..
Haven't a clue how Heathrow, Gatwick, JFK, KLAX would fair. Small aerodromes might not be that difficult either - usually always some kind of area nearby where a station could transmit from..
Hmm..will give it some more thought and probably post on the relevant, well read ham radio websites/forums - see if the idea is a real possibilty or not. I'd be "up for it", but not sure if it would gather pace ..
Cheers anyway...
