Question about Cobra 29 Lx Full-featured Cb Radio
I want to turn up the output power on my radio myself rather than paying someone else to do it
Pay and get it done right so the radio does not get destroyed.

Only a qualified technical person is allowed to do so per FCC, (Federal Communications Commission). That means what it says. If you are not one, then you cannot do this procedure....hope this helps....

Here is a link to the Phantom CB's seb site, you can click on the brand of radio you want to peak, in you case, Cobra. Then follow through the chart to the Cobra 29 LTD Classic under the Cobra power mods, which tells you what to adjust and changes that can be made. Only one suggestion I have before you start, where it says to cut D11, don't, only turn up VR-4 for your modulation. That is the only thing I don't like with their instuctions is telling people to cut the modulation limiter. You can get full modulation by turning up the potentiometer, and if you cut the limiter, sometimes it will over modulate.
You need an inline power meter to peak the radio out. This is the quick and dirty way to peak and tune a radio. To properly align a radio, you really need an oscilloscope and other related test equipment.
If you have more questions, don't hesitate to post here or email me at [email protected]. I can't promise I will have an answer to all questions, but I will do the best I can to help.

un-solder 1 leg of D11 diode, pull it out of the board, and make sure it does not short against anything.
That will bring your modulation up all the way. there are other adjustments that can be done, but without proper meters, you will most likely mess up the radio.
D11 will be a big step up any way.

If you're using the RFX-75 amp section. Then you'll need to make sure your transmiter section is tuned for full output. The last last unit I installed in a Cobra 29 LTD, the radio modulated right at 100 watts output.
Hope this helps,
