Default trouble with hum

wrote in message
news


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.
