No you can't! I repair radios for the USAF. Some of my HF radios (2-30 MHz) put out 5000 watts none of them bleed over onto any of out other radios or even the little radio we have to listen to music.

With a linear amp your CB acts as an "Exciter". A switch will be instaled to turn the standard 4W down to about 1W. This 1W of RF will be used as a reference for the amp.

A linear amp is a little difficult to explain but here goes. It will have a linear (meaning straight line)power ramp. There will be no power curve i.e... If the amp has a peak power of 100W and a min of 0W then the dial when set to max power will put out 100W or if it is set at 80% of its rotation then 80W will be radiated ect....

If you were to graph the power output to the dial setting the powe would be ploted ans a straight line rising from (0,0) to (100,100) i.e ther would be no power "curve"

Skip happens when charged particles from the sun bombard the ionosphere (these are the same particles that cause the Aurora in the Van Allen Belt)
saturating it and making it esentialy a mirror. I have set radios up to intentionaly transmit 3/4 of the way arround the world (for the USAF) when skip is in full effect.

Going to agree with bofr84 on this one. With just a little Palomar 250W Liner (actual output around 175W) I have personally spoken through the speakers at Sonic, household intercomm system, a little kids walkie-talkie set, a friends CB that was POWERED OFF, and it had the cool ability to reset gas pumps at Chevron. Your mileage may vary.

Channel 4 is what my group has used. I'm not sure if that's a standard or not? Otherwise all your traffic is on 19.

Default Garman Rhino

Everyone in our hunting group carries a hand held Garman Rhino. The great thing about it is it is also s GPS that has the ability to pinpoint and lead you to whomever you are talking to. I got one of the first ones out and just as you would expect they have much better ones out now. Cabelas is just one of the many places you can get one.
Have a Great Day, GRIZZ

Default cb radio

We use the cobra handheld. Mainly for the small size in one package easy to mount. You do lose some signal strength with distances though.

Maybe I'm a smart ass, but why not just transmit only 1/4 in the other direction???

I have the Cobra 75WXST Remote CB http://www.walcottcb.com/cobra-75wxs...dio-p-520.html, bought it off ebay for like $100. The only reason I got this one is because of the size and how easy it is to take out of my jeep. I have junction box connector inbetween the front cup holders and the arm rest/middle console. I also have a 3 foot Fire Stick 2 Antenna http://www.firestik.com/Catalog/FS2-FS5.htm, bought it at a local truck stop. I have the antenna mounted between the spare mount and the jeep. I have a range of about 3-5 miles (never had it tuned) depending on surroundings.

I enjoy going to the casinos (great food, shows, clubs, etc) so I can take out the CB and store it on the little compartment behind the rear seat. I can also take the antenna off and store it right inside the gate. That way, no one can have the idea of cutting my top to steal it and then heading to a pawn shop for some quick cash.

CB raidos (Citizen Band) are public, so I guess you could get in trouble for the use of profanity. One of my pevs is people playing music over the radio. Or people think they are Kris Kristofferson from that movie Convoy.

Where do you guys have your CBs mounted? I saw the JK-Project write-up about storing the CB above the rearview mirror which is cool, but wanted other options.
