Shields Up!

Brent,

 

Geeeez, I hope its grounded.....

 

Thanks for the very clear explanation (except for the tube of water).  Oh, if I only had the time to re-wire my airplane....

 

Anyway, here is a query for you (or anyone else that has pertinent info):  Just what is my GSM cell phone doing (Motorola V3 RAZR) whilst handshaking?

 

Oh, I guess you will need some symptoms:

 

1.  Sometimes I leave my phone in my last-worn jacket that is hung in the closet about 2 feet from an electronic door-bell chime box with remote speakers.  If I should get a call, chirps and R2D2 squeaks are heard throughout the house.

 

2. If I leave my cell on the desk, within 3 feet of my desktop computer's audio system, similar sounds are heard each time the RAZR trades info with the local Cingular cell tower.

 

3. Recently, when I was a passenger in a friend's SE Cessna, he complained that lately he was getting static like sounds in his intercom and some erratic behavior from the AP - I duly noted the same static and turned off my phone.  Some of the static went away.  He didn't believe me (and didn't shut his GSM phone down).  Of course, by then we had flown into the hinterlands where cell towers are rare and there were no negotiations betwixt phone and system occurring.  Hmmmmm, I should check back with him to see if his problems have gone away, or if they are only present when following the interstates.
