hello,

I have a question about CB radios... I don't have one (yet), otherwise I'd
just try this.

Is it possible to speak through the microphone and hear your voice coming
out of the speaker, WITHOUT having the sound of the CB radio receive coming
through?

In other words, can you "mute" the radio reciever and hear your voice in the
speaker?

I have a bus, and I'm looking for a way I can amplify my voice and talk to
the passengers. I thought maybe if I got a CB, I could not only use it as a
CB, but I could also use it to make announcements to the passengers.

If this would work as described, I would connect the output of the CB to the
AUX input of the car stereo that is used to play music in the bus.

Will this work?

Thanks

OK, I did a little more research and found that some CBs have a PA switch
and I guess that's what I'm looking for... but then I need to know... could
I plug that into the AUX input of a car stereo, or will it only work going
directly to its own speaker?

thanks

They are designed to drive a speaker directly. A cheap powerhorn from
Radio Shack and a 1/8" plug will have you in business. All you would
have to do is mount the PA horn somewhere pointing toward the riders.

You could get another speaker or a PA horn; but going to the AUX input would
work. I've done this several times. Be careful not to turn the volume up
on the CB too high, though. The AUX input is probably pretty sensitive. If
you get a loud hum, you might have to get an audio transformer (RatShack
Catalog #: 273-1380) for $2.99. I used one to get rid of hum from using
CAT5 computer network cable to get audio from my Dish satellite tuner to my
computer. The audio is now excellent. Good luck and have fun!
