I have a Cobra 19DXIV, it has been working fine with my "little Willy" antenna, but today on a job I was tranmitting fine but could not receive. The bar showed that someone was talking, but I could not hear. Any ideas?

ant. light should only come on if you have a high vswr a bad thing did you check that cb/pa switch is set to cb check your swr this is not a good place to mount ant. as it is close to metal of back of cab

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!

Had fixed the same problem yesterday. My cobra worked when it wanted to, when it didn't it looked like you explained. I found out that on my cobra the blue wire on the mike connector was broken. When it disconnects, no sound. after soldering, everything works fine.

As I understand from a tech friend of mine, most truck beds are not grounded well enough. Perhaps you could borrow/purchase a magnet mount antenna and locate it on the roof, for testing. Then you would have it narrowed down to the location.

Hi and welcome to FixYa,

Initially, the speaker of course has been checked?

Offhand, would partial schematic of the mic and speaker section help?



Good luck and thank you for asking FixYa.
