I have a Philippine made Cobra 29 that developed a problem yesterday - no sound. When I plug an external speaker into the pa jack and switch the radio to pa I hear radio transmissions, otherwise there is no sound at all. I would appreciate your thoughts on what the problem might be. I live in northern California (Sacramento area) and would also appreciate any thoughts on where to take it for repair. I've had this radio a long time really like it so I would prefer to repair rather than replace it.

Those speaker jacks are notorious for the metal contact strips in them to bend out of shape. Remove the cover necessary to get to the jack. Have radio on and connected to an antenna. Take something skinny with maybe a hook thingy on the end like a dental pick and gently push-pry on the contact strips. If this is the problem, you'll hear the speaker engage. Push-pry on the strips until they've bent back into working position.

I don't use an external speaker, but I did try plugging the speaker into the ext. spkr jack and got no sound. I'm also using the same mic on different Cobra 29 right now and it has no problems, so it's not the mic. I'm thinking it's something internal like a volume pot or something, but I've never done any electronics tinkering.

10-4 Could be several things at this point. Speaker itself may be blown. There's other techs on here who can probably put some good suggestions on you.

Good luck
