I just bought a used 29 LTD Classic that was supposed to be a 10 on working condition. When I hooked it up to my antenna (1.2 match) and powered it up all was quiet untill I turned the RF gain up to3/4 to full where I can here a lot of static. When I did a radio check test, I can only recieve when the gain is set this high and the other set is within a couple of blocks. Transmit seems ok. When listening to the two sets side by side My little emergency radio (Midland hand held) is recieving all kinds of chatter while I only get static from the Cobra 29. I observed the sw meter and see the needle swing but don't here anything but static. The cobra was made in May 2004 . Is there anything I can do to possibly fix this?

Hi you have to make sure your antenna has 1:1 SWR reading improper use of antennas deplete the Effective radiating Power of Transmitting equipment such as the CB radio.

High SWR on antenna system.. may have mess up your RF final transistors. if you were talking on it for a long time. have someone check the SWR on the antenna system... should be a FREE service.

I see two possible problems. First, with a magnetic antenna it is difficult to get the proper ground for the antenna. Make sure the magnetic base is clean as well as where you place it. Second, try running your power lead DIRECTLY to the battery and not using the cigarette lighter. Hope it helps.

HELLO STAN FIRST HAS THE RADIO BEEN PEAKED AND TUNED? SECOND IS THE INTERIOR LIGHT IN YOUR PICK UP RIGHT BELOW YOUR ANTENNA,IF SO YOU HAVE A PROBLEM BUT EASY FIX THE WIRING GOING TO THE LIGHT ACTS LIKE AN EXTRA ANTENNA CAUSING YOUR ANTENNA TO RESONATE TO YOUR RADIO CAUSING THE A W I LIGHT TO COME ON MOVE YOU ANTENNA BACK A LITTLE FUTHER AND SHOULD BE GOODif you want to get a bettter antenna get a willson 500 mag mount far better

Not if the power output from radio to amp is set correct and the jumper for coax is correct length and there is absolute perfect match between them and the antenna used. Afterthought: also the amp better be connected to something big enough to power it.

You are actually tuning the antenna to the vehicle it is mounted on here are some very good resources. http://www.rightchannelradios.com/pages/cb-antenna-tuning-guide-pv-c0-61.htmlhttp://www.wilsonantenna.com/swr.php

Be aware that if your radio has been modified it may produce a dirt signal that an swr meter may read as reflected power. In this case it may be more accurate set with a unmodified radio also if your radio is setup for a linear it may have a deadkey to low for the swr meter to calibrate correctly.
Hope this was of help.

Try making sure the RF gain is up all the way. Make sure all connections are good and tight, use the best antenna you can get. I love the 102 inch steele whip myself, just depends on what vehicle it would be on. conditions here the last few months have been pretty good for 10 meter ham and other ham bands, pretty bad for cb because so much skip/

Start with the antenna that you have hooked to it, is it grounded, is the coax in good shape, is the connector in good shape. stuff like that.

As I understand from a tech friend of mine, most truck beds are not grounded well enough. Perhaps you could borrow/purchase a magnet mount antenna and locate it on the roof, for testing. Then you would have it narrowed down to the location.
