Cobra 25 ltd wx classic
the mics on these cobras have a receive wire in them so the transmit will still work even if the receive wire is broken,if this wire is broken the unit will not make any sound...........remove the plug from the radio end of the mic and check the connections on the 5 pin connector.....(could be a cold solder or broken wire) or try a new mic or one that is proven work on another radio
hope this helps.................good luck!
Blown fuses
no need for wiring diagram just replace the reverse polarity diode. Look at where the power wires come into the radio and you will see a diode. that's the one to change.it should be a 1n4001

L 19 is the adjustment can for the N/B . If you choose to adjust it then turn it a little at a time. If it still doesn't work right then let a tech take care of it.

there is the problem. a $150 repair bill for a $ 25.00 problem. After you put in this new IC did you put it on a scope to check it out.How about a frequency counter to make sure you were on the right frequency? take it to a tech and let him fix it .
How do i adjust dead key on a cobra 25 ltd classic cb
The only "adjustment" is the AM POWER trimmer. Lowering this will lower your dead key but will also lower your "swing" power. the TX circuit must be modified to lower the dead key and maintain full output. there are many articles on the web for such modification.

check VR4 to make sure it isn't closed . Check D 11 to make sure it isn't clipped . Turn VR 4 clockwise till it stops then back it off a little .If D 11 is clipped replace it with another diode then try it again. If it doesn't work it could be your final or your driver so replace both..
