I am broadcasting my scanner over the internet and the sound is fine
until
it
gets to the 460 range and then there is a hum. I went out and bought a
shielded
cable for my scanners connection to the sound card but it did not help.
Any
suggestions on how to fix this?

Try a 0.1 uF Tantalum cap on the center conductor. IOW, interrupt the
center conducter and install the cap inline between the scanner and sound
card. Also, I would strongly suggest you install a 1:1 isolation
transformer
between the cap and scanner.


Thanks.. this is beyond my capabilities.. is it possible to buy something
like
that?


You could buy a rigblaster. They do all the level interfacing for you. Or,
you could buy the part from Radio Shack. P/N is 272-1434 $1.59
