Has anyone come up with a cure or solution for the audio output of the Cobra 200 sounding nasal and under-driven. |

have found that a couple locals using 30 amp & bigger power supplies have better audio then when using 20 amp & smaller supplies. |

Why not use a car battery to power the radio. |

car battery will need a sufficient charge presented to it. the cobra seems to draw a fair amount of current(more like an amplifier, then a CB radio), and voltage drop will occur rapidly. put a stock CB on a car battery, & even as voltage goes under 12, it'll still sound alright. as soon as the voltage to the cobra drops, it'll sound funny. |

Thanks, but my poor SSB audio output is not power related. I suspect that the ALC limiter in this radio causes the poor audio output. Does anyone know how to clip or open the ALC for this radio? The older radios used a RV to control the SSB ALC output, but this radio doesn't have one and the SSB modulation is restricted to less than 95%. |

defeating the ALC caused problems in the originals. in even the new ones, defeating it makes 'em sound worse. |
