The signals that it picks up are all around and through the cockpit of the plane already regardless of your GPS or not. United seems to be okay with GPS to be used in flight. I had not problems several times, although it only worked right next to the window (request a window seat). Some radio receivers do emit electromagnetic radiation in the frequency band used by pilot communications (116-136 MHz). The internal amplifiers of the receiver used to amplifiy the signal from the antenna will emit this EMR. I have been able to test this at home with a normal FM radio and a scanner in the above mentioned frequencies. I imagine though that the amplifiers in a GPSr work at much lower levels (amplitudes) since they do not need to emit sounds.

This is wonderful. Thank you. It's almost eery seeing ones own handwriting, but nice to remember a cache found many months ago.

There are usually monthly or bi-monthly meetings of local geocachers here in Austin. This would be a great chance to meet fellow cachers, get advice, share experiences, etc. You may even talk someone into selling their used GPS unit. ;-) Check the event caches for the next meeting time and location. The Geocache home page (scroll down a bit) is the easiest way to see these. -chloew
