Model year 2000 COBRA 25 NW ST CB RADIO

Contact Cobra here Support Cobra Electronics Corporation

The Modulation adjustment is VR5, or you can cut D9, though I do not recommend completely disabling the AMC circuit. If VR5 does not have enough range, lift the banded end of D9 & solder a 1K-ohm resistor in series with the diode, then adjust for 100% modulation or to where the AMC circuit just starts to limit modulation.

It sounds like the switch is bad. I'd have Cobra warranty it for you.

If you have not bought it yet some dealers may have them already set up.Cobra is a popular radio so before you buy ask. you could just match it up to a cobra 25 mic though.

Hi Davis, please post on CB radio forum, this is Radio scanner forum.

you are not planning to talk on this radio are you? Install your antenna where you can get the most out of it.Such as on the front right side near the windshield or install a mount near the top drivers side rear.Any way you should make sure you have a good ground and an SWR under 3:1 @ 3:1 you are losing 75% of your power to the radio and coax and 25% to the antenna but the lower the better . Try different places on your vehicle as to where you get the best place to put the antenna. Get a feild strength meter also,it will help you find the best position.

you probably had it plugged in wrong to begin with. get an external speaker and plug it into the external speaker plug on the back of the radio.

did you repace the driver aswell
