You need to check the modulation on a modulation meter. Just because the meter doesn't peg, doesn't mean the modulation isn't working. Usally a meter pegging, means the swr's are too high or the meter is misadjusted. If in fact the modulation is low, their is a pot inside the radio (VR4) that will add gain to the modulation circuit. This setting is legally supose to be set by a qualified technician.

Hi,i have a cobra 29 ltd radio .the problem is this i can hear prople great but when i key up people barely hear me even thou i have my mic gain up and dinamic up as well. also when i key up my cb makes i...

You said mic gain and dynamic as well. After market power mic? Battery in power mic good? and is it wired for that radio? Running a "mag mount" antenna? Make sure your radio "power" itself has a good ground. In some cases the chassis of the radio may have to be grounded as well. Your getting some type of feedback, whether its audio or RF related just might have to play with it a bit.

My Cobra 29 LX receives including the weather but can't transmit

If the relay contacts are closing. You may have blown the output transistor, however a broken wire in the microphone can also create the symptoms you describe. .

you can check by using a #47 light bulb soldered to a PL259 connector as a dummy load. If it lights, the carrier is present, but you may not have voice modulation which will show as differences in light intensity as you speak. If no modulation, the microphone is the first thing to look at.

The relay contacts may also be very pitted or corroded and not achieving continuity.

Cobra 29 has a 5 tone roger beep . It works fine with a stock Mic . But when I use a d104 I get about a 2 second hum instead of the beep.Any ideas on what is causing this. Thanks

The d104 is a power mic. For what you have explained you have something gone array in your mic or the mic plug. The fact the d104 is a power mic should not make anything hum. With a lot of power behind your CB and the power mic things can sequel with the mic gain turned to high. But a hum is more than likely a bad mic. Try another one. The same kind of mic should be fine.

Cobra 29LTD CHROME low tx no mod, rx good low Vol, talkback good

1 why would you change the finals?? Have you checked you antenna? How are your SWR's? Crappy antenna's cause a lot of problems.

Use an external meter to see what the SWR is, and see what the output is PEP. If its low, then there is something wrong. If it is High, change the mic and turn up the dynamic all the way.

Next. Have you been messing around in there?? Tryin to get more wattage? You turned VR4? If you thought you were turning it up by turning it all the way to the right, you turned it all the way down. Turn it all the way to the left.
