[linux-audio-user] Re: Radio Interference problems when recording

[jmacdermott at dopd.com]

Thanks to everyone who offered suggestions to my radio interference problem.  I
am hoping thay I'll get some more time on the weekend to investigate it
further.    Sorry for the delay in responding to the replies I received, but
here goes...

It's radio.  I don't think lighting is the problem, nothing unusual around the
equipment that wasn't there before.

Thanks for the tip, I may have to look into something like this.

I'm not sure what you mean by ferrite beads, or how to place them on the cables?
 What leads are the hot leads on the cables (I assume you are referring to the
XLRs?)  Sorry for being so dense, but I'd appreciate it if you could explain
this to me in greater detail (like a two year old, say?) ;)

Thanks again to everyone who replied!
