m> How about an IMAGE of an AM transmission heard on an FM band?
m> So, I whip out the calculator and sure enough,
m> 154.935 - 21.4 (2*10.7 IF) = 133.535 lands me right in the
m> AM Air band. Three questions:
m> 1. What does an AM transmission sound like on FM? Garbled?
It does sound kind of garbled, almost off frequency sounding. You
will know there is a voice there but it isn't very clear.
m> 2. What is the likelihood that an AM image will show up and
m> break squelch on an FM band 21.4MHz above?
Depends on your scanner. I have a Bearcat 210XL and Bearcat 160 scanner
and both of them will pick up images of aircraft on 155.1000.
m> 3. 133.535 MHz I do not recognize as any frequency being used
m> by either Cleveland Hopkins or Akron/Canton airports. Does not
m> show up anywhere in Police Call. (which really did not surprise me)
m> Any insight from anyone?
Hmmm....it may not necessarily be for an airport. Several air carriers
have freqs to communicate with air crew on the ground that is for their
compnay. You will see these at the back of the Police Call book...usually
in the 130 range. I suspect that this is not a complete listing, though.
