Sounds like you need a tech to "ALIGN" your radio! I have one of the same radios I bought at a yard sale last summer. I just haven't taken it to a tech yet. I have to many radios! lol

What size fuse is used in COBRA 29LTD CLASSIC radio.


First question should be, what happened to the last one? If the fuse blew on you, you need to find out why. If it was just missing when you got the radio...

That said it is surprising that the manual doesn't state this value directly. However, it is a 4W transmitter and the manual I referenced states that you should connect to an "accessory" fuse for mobile installation. My car has a 10a fuse in that position but a 3A slo-blow in the power wire's inline fuse holder should do the trick. (The main reason for using the "Accessory" fuse is for operation with the engine off, but not battery drain unless the key is inserted.) Another clue for my SWAG is that for a "base station" installation, the manual recommends a 12Vdc power supply that can deliver >2A... So I think we are in the ballpark.

If you have lost your original manual you can get a replacement from the Cobra support site here:

Cobra 29LTD Classic RX seems to go off frequency. Transmit is fine, but can't receive on same channel. i.e. TX on Ch 11, but RX some other frequency. Was talking to my wife and suddenly, her signal was...


all functions of the radio are performed by the main IC 2816c . The frequency is controlled by this also and if it is blown you will loose your frequency and the problem that emits is in your statement.

New Cobra 29 ltd


Hi,

Appreciate the direct "Ask Me". If I may clear up your concern:
  • you have two CB radios, one is a Cobra 29LTD and the other?
  • both have received and both do not transmit;
  • you have two trucks, one with a Firecracker 1000 antenna, and the other?
In any case and initially, TX (transmit problems) could be caused by:
  • defective PTT/mic;
  • defective finals/drivers;
  • defective PL-259 connector/RG58 Cable;
  • antenna grounding/SWR;
  • other electronics internally
Please check the above. You may need an SWR meter, a watt meter and a DVM/VOM to perform the tests.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Hi,

Appreciate the direct "Ask Me" again.

The initial posting would still hold true, best would be:
  • remove TR18;
  • replace 2SC2069 with 2SC1969; and
  • adjust L12, 13 & 14.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
