Title: just got my new CB
Post by: Corey on May 01, 2009, 10:39:34 PM
Just wondering what chanel most people run while in the bush?

Most of the time, the CJA runs on channel 10.

Red Deer Jeepers have adopted the same channel 10 as the CJA.

channel 9 is the "emergency only" channel if i am not mistaken. so if you get into some hurt, switch it on there and make some calls, but dont mess around on that channel cause you could get in sh*t from the air time regulator guys.

Also make sure that you tune your antenna before you start transmitting. If the antenna is reflecting too much of your signal back to the CB, you could potentially damage it.

If you don't know how to tune, there are a bunch of threads on this board that will guide you.

I had no idea. I instaled the radio and installed the antenna on the back of the spare tire. There is about a foot and a half above the jeep. The radio is a cobra from the 80's by the looks of it. Back home I had a midland with a 30ft groundplain whip on my house with a power microphone.

Officially the CJA channel is 13 from back in the old days but we never seem to use it any more  :'(

A foot and a half above the jeep = probably good. From what I've read, you want to get as much of the antenna above the roof as possible - but bear in mind that with modern fiberglass whips, there's wire wrapped around them. You want to get as much of that wrapped segment above the roofline as you can.

The other thing is that "ideal" performance out of a CB on the trail isn't as important as making sure that your antenna doesn't get ripped off you Jeep when you're squeezing through a tight spot - or going into an underground parging garage.

CH4 is the channel most commonly used channel in the bush by 4 wheelers unless you are running with a club that has adopted another channel. CH19 is most commonly used b truckers and is good for getting traffic information.

CH9 is reserved for emergencies but no one monitors it. DO NOT USE IT WHEN TRYING TO CALL FOR HELP IN THE BUSH! You won't get anyone cause anyone in the bush has their radio on CH 4 or 10 or whatever their club channel is. You MIGHT be able to get a trucker on 19 depending on how far back y0u are.

So I think I need to upgrade the coax cable and figure out why all I get is static when the jeep is started and none while it is turned off. I have it hard wired to the battery. Could anyone help tune it so it will work?  Still a huge nubie! 
Thanks Corey

Does anyone have an SWR meter I can borrow?  (I just bought an awesome antenna).

Lots of amateur radio operators on here I see.  I don't want to buy an swr meter for one time use.  8)

This is a common problem. One of two things may be causing it:

#1. Your stereo is not turned up loud enough.

#2. You accidentally fit AT  tires to your jeep instead of boggers. Switching to boggers immediately will prevent this static noise from bothering you.

The static is usually caused by the alternator or interference coming through the cb's power source.  You can get a ground loop isolator/noise filter which goes inline with your cb that should take care of the noise.

Somewhat related question if I may. The mounting of my antenna can only be described as an act of pure idiocy although it works perfectly. The location suggests there was drinking involved. I just received some goodies from UPS which includes one of the brackets that install behind the tail light offsetting the antenna to the outside of the taillight itself. How do others route the cable inside from such a position? Once inside the cable is neatly routed up under the lip of the tub in the same factory clips holding the rear wiper cables and washer fluid line.

I've never mounted an antenna to a TJ, but I'd wager that you could route the cable through the hole in the tub where the tail light is mounted.

I have the Neg and Pos coming straight from the battery, with a fuseable link on the Pos.   Have the CB mounted to the right of the ashtray on the pass side.  The antenna cable runs under the dash just below the stearing column and up through the driver door where i have the antenna(magnetic type) on the roof pretty much right over the drivers head.  Anything wrong with this set up?    I was all over Calgary yesterday and even by the flying jay, and I had a ton of trouble just hearing anything.   Ever 5 mins or so i would hear someone trying to say something, but I can seem to tune into it.

I seem to have under estimated the good ol' CB ,  I thought it was a Plug and go kinda thing.

(Take that as yet another pitch for 2 metre amateur equipment, which uses FM and is way less susceptible to noise, the same reason FRS/GMRS doesn't have much noise  :D)

Are there a lot of people who wheel who use 2m?  I was thinking about picking up another 2m radio to install in the jeep, but wasn't sure if anyone used it or not.  Also, what freq. are people using out in the bush?  Simplex or a repeater somewhere?
