Its just plain good sense not to use cellphones in an aircraft. Has
anyone noticed how a NEXTEL phone will tear up speaker phones and

Nope. I have both right here and with no problem.

My old phone, or old service had problems. It would periodically talk to the
cell tower, doing whatever it is that cellphones do. The RF couples strongly
into my audio systems. It was most noticeable in the office when I set the
phone down next to the PC's speaker wire. The amplified speaker made it very
audible; it's louder than normal audio coming from the PC. (I'm qualified to
speak to RFI and EMI in a way you might accept; I hold a fast code Extra

CAT scans; country where you'll find Calcutta.)
