That's a new one for me, Naperlou. I haven't experienced that audio bleed from cell phones. Is that a common occurrence?

I have the same problem in my car.  When my ATT phone talks to the tower to change towers, it transmits and meses with my radio.  I have to have it far away from the receiver to avoid the irritating buzzing.  But I don't blame the cell phone.  After all, who expects to place a transmitter so close to a receiver without interference?  That's why we squelch the radio during transmit, normally, in ham radios.  Plus, we aren't always duplex, but that is another story.

Frank, that was an iteresting experience.  Today we have a similar issue with cell phones.  I am not talking about the regulatory situation, but about interference with audio equipment.  My son first told me about it in regard to a situation in middle school.  Students were not to have cell phones in school.  If they had them, they were to be turned off.  Often, though, they were not.  In classes with computers the teachers noticed a buzzing sound coming from the computer speakers.  They soon figured out that it was the cell phones, and it allowed them to "catch" those students who had their phones with them.  Now this happens only with the at&t GSM phones.  I had a Verizon phone which used a different frequency and transmission type (CDMA).  I did not notice interference with audio equipment with those phones.

Those were the days

Nice look back at life prior to the onslaught of computers and devices. Going into that MIT lab and seeing the spread of computers must have been eye-opening then. Today, you'd see a comparable set up in an office and even in some homes. Also pretty eye-opening that the FCC wasn't governing the computer spectrum back in those days. Shows you that Bill Gates' vision (and others) of a computer on every desk was still pretty much considered a pipe dream.
