CB Radios and Relay Towers

`A buddy and I have portable Citizen Band Radios and we were kinda wondering what cool stuff we could do with it. Also we want to try and build a simple Relay tower to be able to talk to extend the signal. How would we go about doing this?

Sure, but that's for ham radio and they have CB's. True, there is all kinds of cool stuff to do with ham radio, and there are repeater "towers" everywhere all ready especially on the 2 meter band.

. CB _is_ ham radio. 744 hits for CB on the ARRL site.
Citizen's Band (CB) used to be a Ham frequency, but was given to CB'ers in the 70's, much to the dislike of the Hams. Budd

Na CB was created in the late 50s long before it hit the big time in the 70s. Before that craze most people used it as it was intended. Inexpensive short range personal communications

Citizen's Band Radio service was originally 11 meter amateur radio, a favored skip frequency band. Yes, at one time it was a UHF band but as you can read, that was short lived due to high component costs ... those old vacuum tubes just didn't like high freqs like solid state devices do and required special (read EXPENSIVE!!!) construction techniques.

Probably the http://en.wikipedia.org/wiki/Amateur_radio_repeater#Simplex_repeater would be the easiest, Although a full on full duplex repeater would be fun to build. Problem is either would be worthless for local communications when the band is ope. Of course both are probably still illegal to operate in the CB band.

Certain days and times of the year, one can bounce the signal off of heavy cloud cover, or with a particularly strong signal (and with a bit of delay, I might add) off the moon. Oh wait, I do believe I am referring to SW, and not strictly CB

It generally takes a lot of power, 1000 watts, and works best for morse code. It might be interesting to see what you Can HEAR by pointing, perhaps, a common rooftop TV/FM antenna at the moon and trying to hear any stations. Forget about the video. A full moon is not the best time because the sun makes static in space, which you know if you watch satellite TV around the equinoxes. It may also be interesting to point the antenna at geosynchronous satellites and try to tune in "different" signals. They should passively bounce more clearly than off the moon.

I have heard some stories (and they may just be that too) of guys doing wonders with 5 watts. But that has to be rare indeed (if they are actually true) and yes, that was with morse code.
