More cb help

I didn't want to take over Nevada's thread so here's my own. I recently got a new cobra 29 ltd classic. I hooked it up and wasn't sure how to tune it so I just left it as it was. On a run sunday it was working great, I could pick up and call out great.

Today I was headed out with my buddy following me in his truck and we were talking just fine but then all of a sudden I was getting a squeeling so bad that I couldn't even hear him when he was talking. I could still talk and he could hear me perfectly clear but anything that came into me squeeled very bad.

Also, what's the best way to tune all of these nobs?

HIS radio was squealing, not yours.

the only real tuning it needs is the SWR set. these come with a built in guage, but some say they arent that accurate. id set it with the built in guage, and see how it works. if you dont like it, a radio shop wouldnt charge much to tune it. or you could buy a separate guage.

set your dynamike to full. you may find that you need to adjust it down, if ppl have a hard time understanding you. but start fully on first.
RF gain to full also. unless your very close to everyone in the group, then you can turn it down a bit.
i dont remember what to do with the delta tune. i think i keep mine in the middle.

to set the SWR. set the selector to CAL, key the mic, and adjust the SWR CAL knob until the needle is at the little CAL arrow(far right) on the gauge.
release the mic, set the selector to SWR, key the mic again. check where the needle on the SWR scale. the lower the better.

if its HIGH, you need to adjust the ANT. hopefully its the screw type, as these are VERY easy to do.
screw it in or out, and recheck the SWR. once you have it the lowest you're able to, its tuned. hopefully you get below 2:1

also, you want to use a median channel. the SWR will be different for ch 1, than it is on 40. if you ONLY ever use it on a lower channel, you can set it for that.

if anything is wrong, PLEASE correct me. im going strictly off memory here.

ok, ive got to edit a bit.

check the SWR as i described above. do it on ch1, and ch40. if ch 1 is HIGHER, adjust the ANT screw OUT. if ch40 is HIGHER, adjust the ANT screw IN.
and yes, leave the delta tune in the middle.

checked my internal meter, against AJ's radio, and he said its accurate. hopefully your's is also

When you adjust the tuning screw in your antenna, turn it only a half-turn at a time and remember which way you turned it and how many half-turns. Like adjusting a carburetor. It shouldn't take much. I don't know where you have your antenna mounted, but ideal SWR is 1:1 when the antenna is mounted in the middle of the roof. Most of us end up mounting them behind the roll cage, behind the cab or in other less than desirable locations and tuning them to a 1:1 is virtually impossible. If your antenna location is close to other metal objects be happy with as much as a 2.5:1 SWR ratio. If you need help tuning it see A.J. Radio One, 311 W. Pine, Yakima, Tue-Sat.
