Your SWR is probably NOT fine. You need to use an external meter if you have had work done to the radio. Especially if you have had a swing mod done to the radio. When you do this, the dead key of the radio is lower then the calibration knob on the radio can adjust for. It will always come up lower then it actually is.

Your radio might have been fine before the work was done on it because it was putting out very little power. Now you are most likely putting out 50 watts or more. Big jump from 4 watts.

When your raise the power in a radio, you will notice more when the antenna is not properly tuned.

In most cases with a stock CB, even when the antenna is not even near tuned, you will get a reading less then 1.5 anyway.

the more power you put out, the more important it is to have a good match.

But an external SWR meter, and check it. be careful if the ANT light is on.

You might also want to check your coax, connections to it, and your antenna for anything wrong.

Don't worry about that I had the same thing on my Cobra 29ltd classic. It does that when you are running around 40 watts power out with Swr 1.3(its just a red light that shows you are talking after you have the mod done to it. Mine would talk to Oklahoma from Kentucky on USB Ch # 39 Amazing how much it improves it to have mod & upper channels installed.

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.

Cobra 29 NW LTD Classic wont calibrate and red antenna light keeps coming on


The calibrate knob only calibrates the radios SWR meter, the owners manual will show you the procedure for that. If your ANT light is coming on, it is telling you that your SWR is to high, and may cause damage to the radio from reflected power. You should purchase an in line meter as the radios internal meter may be somewhat unreliable. You need to tune the antenna to the lowest SWR possible. Typically anything under 2.0:1 is acceptable. Radio Shack sells a meter for about $50, and is pretty accurate. Antenna mounting can also cause high reflection if it is to close to other objects. Google "CB antenna tuning" or read the instruction manual for you antenna, and you should be able to figure out how to properly tune the antenna.

Cobra 29 ltd classic side mic


First off I dont believe anyone to peek and tune but anyways. Make sure your mike is for the radio wiring. Next the guy that rigged it up might have gave you all the channels do all your knobs work??? usually you can tall as you get someone to talk with you a few blocks away and start, start turning and flipping switches till you can hear him most likely the guy that did the work on it messed it up. for a filter use a farite choke from radioshack on the mike wire.

Cobra 29 LTD Classic not transmitting or receiving


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.
