[gui-talk] static problem and question

Fri Nov 7 19:47:12 UTC 2008

Yes, I know about the cell phone interference, however, I have had a lot of 
interference with my various recording devices playing static when my cell 
phone is about to ring, and that interference doesn't sound at all like this 
speaker static.  (Actually, while it's no fun hearing static from my cell 
phone, it is nice to have advance warning that it is about to ring.  In 
particular, it is like clock work while riding in my family's car listening 
to my old talking book cassette player, the interference from the cell phone 
sounds almost like a modem during dialup.)
I'll just chalk this problem up to random radiation, or more likely, it has 
been used so long perhaps it is about to die.  I kind of hope this happens 
as I'm looking at a new set of speakers that sound interesting... Oh, but 
don't tell my old speakers -- they might react negatively -- but alas jaws 
just let the cat out of the bag...*smile*
Sorry, I'm in a joking mood...

GSM cell phones also commonly produce some interference -- I believe
you have a KNFB Reader.
