Where do you find make and model?

La radio Cobra XLR CB es un modelo m?s antiguo, por lo que es posible que no tenga un n?mero de serie. Para averiguar el a?o de producci?n, puede buscar el n?mero de modelo en el sitio web de Cobra o ponerse en contacto con su departamento de servicio al cliente para obtener m?s informaci?n. Adem?s, si planea vender la radio, es posible que desee consultar con una tienda local de electr?nica o radio CB para obtener una estimaci?n de su valor.

I have a cobra 29lx my back light isn't working and buzzing from speaker

Hi, please update your power source and move your device away from anything that deals with using frequencies like other radios, microwaves, active walkie talkies or antennas. Being close to these things could cause interference with your device leading to the buzzing that you're hearing. Thank you

I have a cobra 29 LX BT. It turns on but I can't get any of the buttons to work. The dials seem to work but I'm not sure since I don't know much about cb radios. Any help is appreciated.

Hi, Please double check that your device has new batters or is charged up properly. Then, you would need to have a means of testing the device through instructions from a third party like a radio station/center or other organizations that broadcast to devices like your own. To further learn how to use your device, you can peruse it's manual. Thank you.

I can hear people talking, but they can't hear me, or they say I sound like an alien

Check to see if the meter needle is swinging backwards when you key up. If it does your final may be bad. If the needle goes forward and others say they see your keying up but no sound your audio chip may be bad; especially if you have tried so many mics and antennas. If your radio has a swr warning light and it comes on this could extremely limit your range and others may not hear you and contiued use will damage your radio. Good luck!!!

I need to know what type of antenna should I use for a 1993 model cobra 29 LTD Classic . Both mobile and base?

There are a lot of antennas on the market, you need to be wary or some of the cheaper ones because the corrode quickly. Antennas are a very important part of any radio setup and they can make or break your signal. I use this company and I highly recommend them: Sirio Antenne - HOME

Cb is Keying Down instead of keying up when trying to talk

if you are transmitting fine Don't worry about the meter. Get an external SWR meter, they are better anyway.

Also, make sure the the switch next to the meter is all the way up on s/rf setting. thats for signal power and receive strength.

I have a cobra 25 classic. When I hooked up the mic and keyed down it smoked? It done when I put the battery on it

No aerial/poor connection to the aerial will cause the PT to burn up taking the 2A fuse out. If there is no fuse you will have the added delight of repairing the burnt pcboard inside as well as a new power transistor.

Cobra 29lx Ohms resistor r56 keeps blowing up

You need to be an electronics engineer to diagnose why a component continually fails. It obviously has too much power or the replacement resister is the wrong value, or a component on either side of it is failed and also needs replacing. Get a quote for repair or put in a warranty claim.https://www.cobra.com/pages/repair-information..

How do I turn down my power on my cobra 29

This is not a user-accessible function. You would need to take the radio to a qualified repair person, i.e., a CB repair shop If the radio power output is 4-watts or less, as measured by an accurate wattmeter connected to a dummy load, then there is no need (from a legal perspective) for reducing it.
