Thank you for the input.
 We will see how I feel at the time of the flight. If the Captain is greeting the passangers I might ask. The worst he will say is no. And, I can live with that.  146.520 is probably the best place to try. That way it will eliminate any chance of bringing up multiple repeaters.
 The funny thing is the same day I posted this question the Du page repeater Lunch Bunch asked a similar question. " Do you take your ham equipment on vacation"

 The answer is probably no. But, can you use an HT on an air plane?  Shortly after take off they say you can use computers.The other problem would be you are inside a metal can.
 It would be neat to say portable, commercial plane.   Think of how many contacts you could make while flying across the country?

 Thank you for the advice. I had seen the reset instructions in the book before, but impatients got in the way. I'll give that a shot and see what happens.

 Good morning
 In the past I have successfully added frequencies and PL's to the HT and everything worked fine.  Now after attempting to add additional repeaters to the HT I am unable to hear anything. Not sure if other settings (factory presets) have been changed and that is not allowing sound. As far as I can tell all the settings are ok.
Is it possible to clear all the saved frequencies and start all over with the factiry presets?  Thank you.

Good afternoon

 Today while online I found Hamsphere. Is it an informative and easy to use web site. Is it possible to listen to ham radio on line while on the web page?  Thank  you

 What is the correct expiration date for the ARRL, General Class License manual?  Inside the book it says June 30,2010. If you look @ the ARRL web site is says valid until June 30, 2011. Which one is correct? Thank  you
