Hm, that is an interesting problem. The trick would be to have a signal
that's always considerably stronger at the walkie-talkies than the
CBer's, regardless of where they might be in the house or on the
property, but always considerably weaker than the signal from the other
walkie-talkie. That won't be easy, if it's possible at all. Your best
shot would be to use another walkie-talkie, because it would be directly
radiating on the right frequency. It'd also be legal, for what that's
worth to you. You'd need to reduce its signal output by shielding,
cutting down the antenna, reducing the battery voltage, or some other
means like stringing ferrite cores over the antenna. But I wouldn't bet
on its accomplishing what you're trying to do, unless the CB
interference is pretty weak. Reducing the walkie-talkie receiver
sensitivity is another option, if the receiver is separately accessible
internally and you know enough about such things to do it. But I think
the best idea, suggested by another poster, is to contact the FCC. The
law can, occasionally, be used to your advantage.

Roy,
Thanks - Mike posted about sky waves (I was unaware of), so even a very low
power device centrally located in my property would apparently be heard
world-wide - which is NOT what I want.

Actually, I did want to jam the reception of the existing CB signals on my
property (at least in and around the house).

One of my neighbors uses rather 'salty' language and the local kids use some
walkie talkies around the house - I fugured that jamming the outside signals
would still allow the kids to talk due to their close proximity.

Thanks again.

There's no way to make a signal stop at your property line, short of
putting a perfect shield around your property. And if you did that, you
wouldn't be bothered by your neighbor's CB anyway.
