I have a cobra 142 and it works great except the speaker volume is very deep. Its almost some one switched it to low tone and threw away the knob. How can I make the tone crisp and clear like all my other radios? Oh and by the way, my loop oscillator allignment am/lsb/usb, keeps drifting of freq. why is this? It seem to be heat related. How can this be fixed? Please some one help me with my speaker tone problem first. |

Is the speaker problem still there when you use an external speaker? The voice coil in your internal one may have seized on you. Just a guess and I may be wrong. Try hooking an external speaker to it and see what that sounds like if you haven't already. Does that radio have a tone adjustment knob on it? My Courier has one of those pull type knobs to change the speaker tone, I don't use it because it muffles the sound to much. After a couple ruptured ear drums my hearing ain't all that good so its got to be crisp and fairly loud so I can hear, but not to loud or I get a crackling noise. |

Yes I have tried a external speaker and yes it is still very deep toned. No it does not have a tone switch. This board is used in uniden washington and a madison radio as well and I know surley one of those radios have a tone switch. It would be great if someone could tell me where the switch hooked to the board so maybe i could change it. Thanks for the ideas. |
