Faulty CB??

Bearing in mind that a screening of "Smokey & the Bandit" would probably double my current knowledge of CB's...

Last night I installed a new Midway 1001z CB in my 2001 Wrangler. Wiring was a snap (I do know a bit about electronics... just not CB's), and it turns on fine. I have the power connected straight to the battery with a 40A fuse right at the battery. There is also a 10A fuse next to the CB itself. Then I connected the CB to a 4' Firestick antenna "kit".

I mounted the antenna to the bumper, putting the "white" washer on top of the bumper to insulate the antenna. On the underside of the bumper I made sure the cable connection was grounded to the bumper by scraping the area until bare metal was exposed. Question: Did I do this backwards? Is the antenna supposed to be grounded and the cable insulated?

After getting everything hooked up w/ no adjustments, I'm basically getting nothing, nada, not even static. When I press the button on the mike, I can hear a click over the speaker. When I turn the squelch all the way down, I can hear a quiet humm or buzz, but that's it. I assumed I'd hear lots of static at this point. Obviously, nothing was picked up on any channel either.

Is this enough information to determine if there is something broken inside the CB? I did make the mistake of turning on the CB before the antenna was connected... then noted in the directions that's a No-No. Did I burn up the transmitter???

Have you matched the antenna yet? If not you need to go through and tune with an SWR meter, ideally you should be between 1 -1.5 or 2. As for powering up with no antenna, did you key the mic? If so it's possible you could have blown finals, but you would still receive. Sounds like you just need to tune the antenna.

Tuning the antenna dosn't affect reception, does it?

Hahah, not to any extent that you would notice. Replied to his question before I got my caffeine fix.

Yes there is definitely a problem there. You should be hearing something on the receive side, especially if the squelch is turned down, should have constant open channel static at the least. Either something is wrong in the radio itself or could be the coax/antenna. Use an ohm meter and with the coax disconnected from both ends, radio and antenna, see what the impedence is between the center conductor and the shielding, it should be open. If the coax checks good, then it's probably the radio. Could be from powering up with no antenna, it's possible if the mike was keyed with no ant. there were enough oscillation to blow the final and the receive side.

Thanks guys!!! A friend who knows CB's checked it out for me. Definitely something wrong with the unit. For some reason his hunch was the internal speaker...

Either way, it's boxed up to be sent back. Already ordered another.

Thanks again for the advice!
