[CQ-Contest] RFI tip needed to improve multiplier count

[Mark Beckwith]

Hello friends, I will be visiting J. in September (I'll try to get on for
the NA Sprint if possible) and have need for the following:

What is the best source of snap-on ferrite for telephone/cat5 cords?  I need
to take a bunch up there with me.  J. says he was told not to use the Radio
Shack ones because "they do not have good enough iron so you need more of
them to do the job."

I wouldn't know what this means for sure because I am an Appliance Operator.

Anyway, if some of you actual smart guys out there know *where* to order
*what* from, I'll get after it and I'll be sure to work YOU in the Sprint,
anyway.

Thanks in advance.

Mark, N5OT
