By Scanner,can We Listen To Aircraft 2000nm Away?

Sun Jan 28, 2001 10:30 pm

Hello.

I own a Icom IC-R2 scanner, and always wondered if I can hear a transmission from an aircraft that are flying over Pacific Ocean at 37,000Ft?I heard that I need a special antenna such as Base antenna,but I don't know what kind of antenna should I get.
Can anyone give me a clue about how this can be done?
thanks,

I'm sure someone will correct me if I'm wrong but you'd have to be really lucky to hear a VHF transmission from 2000nnm - it would be a complete fluke. On HF, with an appropriate SSB receiver, it's perfectly possible, especially at night. But on HF you'll only hear route and aircraft information, not tower or approach transmissions.

David L is correct- it is nearly impossible (if not impossible) to receive a VHF signal from hundreds, not to mention thousands, of miles away. But an aircraft at FL370 over the Pacific is equipped with HF transceivers (just above the commercial AM broadcast band if memory serves) which can be picked up from very far away.
