Chances are it was only on *your* answering machine because of the proximity 
of the transmitter to your house.  This kind of interference is very machine 
oriented - or phone oriented.  Since the FCC does not test for interference 
_to_ any devices - like phones, answering machines, *scanners* or anything 
else, there is a lot of junk out there that will pick up this kind of 
interference.
  
The FCC did an informal test of telephones a couple of years back - because 
there are a lot of complaints about this particular device.  What they found 
is that there were only about 3 different models of phone produced for sale 
in the US that would pass an FCC test for interference to them.  Pretty 
dismal.
  
And phone answering machines (and modems), with their connections to the 
phone lines and to the power line ground, are even worse than straight phones 
for susceptability to interference.
  
This is way off topic, so if you want more information, reply to this message 
in FCC or BROADCAST where this topic is of greater interest.
