They won't even let you have the batteries connected. You must also remember
that scanners are so poorly put together that they can really screw up the electronics in the aircraft just by turning it on. Don't take it in your carry on unless you want to be detained and treated like a terrorist. "roadwarrior" wrote in message news:01c4a1d7$84c8a8c0$c698ba89@dnyeaqvf...

Aircraft avionics are, for obvious reasons, made to be very safe. This includes a high degree of resistance to stray RF interference. There are COUNTLESS devices on the ground that radiate FAR more RF interference into the sky than a handheld scanner would and yet we do not see planes falling out of the sky every time they get near a built-up area. |

What a DOUBLE LOAD OF CRAP. Hey dude, it isn't the adjacent channel interference that airlines are concerened with here, it is the stuff being radiated ON FREQUENCY, by poorly designed electronics. You can't filter ON FREQUENCY signals, or you raise the sensitivity threshold of the receiver. The only way to deal with ON FREQUENCY signals is to TURN THEM OFF. Me who used to be a Federal Regulator, and deal with this stuff |

Funny, I have several scanners and all of them radiate interference on aviation frequencies, depending on what frequency they are tuned to. I also have 5 VHF/UHF ham transceivers with wide band receive coverage and all of them also radiate interference on aviation frequencies - any receiver (with a few expensive exceptions) with an IF (a superhet) generates signals strong enough to be picked up by another sensitive receiver close by. Also, every FM broadcast receiver from a walkman to an expensive stereo also radiates on the civil aviation band. Try tuning a scanner to any frequency in the VHF aviation navigation band 108-118MHz, if you are near an airport you should be able to find a navigation signal. Then place an FM broadcast receiver nearby and slowly tune down from the top of the band - you should soon find a spot where you can interfere with and probably totally obliterate the navigation signal.

What a DOUBLE LOAD OF CRAP. Hey dude, it isn't the adjacent channel interference that airlines are concerened with here, it is the stuff being radiated ON FREQUENCY Hehehe! Just testing, just testing. Glad you're wide awake. You're absolutely correct that a scanner might, in some rare circumstances, radiate a small amount of RF on the aircraft radio's operating frequency possibly causing interference. All of this is very much "might" and "could possibly" etc but, obviously, no one wants to be on that particular plane if the problem is likely to endanger anyone. The reality, of course, is that 99,9% of all these bans on the use of various bits of equipment is because they just MIGHT cause a problem, and not at all because most most of them DO cause a problem. The truth is that VERY few pieces of equipment ever cause any problem at all, the airlines just can't afford to take chances though. Many people are under the hugely mistaken impression that aircraft avionics are highly sensitive and temperamental and that just about any electronic gizmo will cause a plane to fall from the sky. The truth is that most everyday equipment is FAR more likely to cause a problem with the electronics in your car than with those in a plane, it's just that the consequences are somewhat more dire.
