Cobra 29 ltd Classic Not Working
Any CB radios need to be in good condition while used. They are used for emergencies and it would be a disaster if they stopped working.
Cobra 29 ltd classic is such a short-range CB radio. It faces several problems like calibration or receiving. Sometimes cobra 29 ltd classic just won’t turn on. It behaves like Xbox one x.
The CB radio not powering on must be caused by wrong wiring. It’ll eventually blow your protection diodes. That surely won’t let Cobra 29 turn on.
This is one very common issue. You might need to check all the wires, circuits, and diodes with a radioshack.
There are some other serious problems that need to come to attention. I’ve talked about those problems in the latter part.
4 Cobra 29 ltd Classic Problems
I’ve identified four problems and also drafted their solutions. Hopefully, this will be enough for cobra 29 ltd troubleshooting.
Problem 1: Cobra 29 ltd Classic Meter Not Working
The prime reason for the meter not working is the wrong calibration. Most people calibrate as per their wish without considering what the manual calls for. This raises the problem.
Suppose, you calibrated the meter at -73dBm or 50.00 UV. Whereas, your manual suggested doing it at -67dBm or 100uV.
This wrong input triggers the needle to go against the right side of the meter. Even your meter won’t be able to detect a weak signal.
The solution is not to replace your meter. Then what is the solution?
Solution:
The solution is very simple. You just need to recalibrate the meter according to the manual. This hopefully, erases the issue.
If you recalibrate without seeing the manual again, your meter will go through premature failure.
Problem 2: Cobra 29 ltd Classic Meter Light Not Working
Some may face a burnt cobra 29 signal meter light. It’s similar to a blinking light on your battery charger.
The reason again could be wrong calibration or default issues.
To solve this, you may need to readjust the bulb or replace with an LED.
Solution:
The easiest way is to replace it with an LED. You can do it in just a few steps.
- First, remove the cover. You’ll see two wires attached to the bulb on the face plate.
- Now, carefully pull that out.
- Clip the wires and keep them unsolder. Your goal is to get rid of the old wires.
- If you’re done with all these, replace them with LEDs.
While installing LED, make sure you’re using the correct resistor. A standard LED requires a 4.7k ohm resistor.
Also, the color of the LED. If you choose a blue LED, you can’t see the red on the meter. So, be careful with these things.
Let’s move on to the next problem!
Problem 3: Cobra 29 ltd Classic SWR Meter Not Working
The reason could be anything but bumping the calibrated knob. Many of you think that this made the SWR meter not work. That’s not true.
Sometimes, you may face the SWR needle going all the way to the right. This is also not the reason why cobra 29 SWR is not working.
The reason could be wrong switching or calibration. You need to check on the SWR meter to solve the problem.
Solution:
To check on the Cobra 29 SWR meter, follow these steps:
- First, turn on the SWR calibrate knob. Do so until it keys up all the way at the end.
- Then click the switch to SWR and key the mic. Now, if you see the needle barely move, turn down the Dynamike knob.
- Lastly, click back to S/RF. And Cobra 29 SWR meter is back to normal.
You may have to spare more to buy a Cobra 29 LTD Professional CB Radio. This is an all-in-one CB radio with SWR calibration.
Problem 4: Cobra 29 ltd Classic Not Receiving Audio
A CB radio not receiving any audio is the worst to happen. The problem could be a bad connection at the external speaker jack. Basically, CB radios use cheap speakers. So, audio not receiving is a common issue.
Also, the weather conditions could be at fault. CB radios are widely used outdoors. Humidity may cause damage to the speaker. Most likely the problem is in the internal speaker.
No worries, I got you a solution.
Solution:
When the internal speaker is faulty, you need to plug in the external speaker. On the back part of the receiver, you’ll see two connections. One is PA and another is the external speaker.
Plug in the external speaker jack into that point. Now, turn the volume up. Also, flip back over the antenna. You’ll now hear the sound.
These solutions are common to cobra 29 nw ltd classic troubleshooting. Hopefully, this troubleshooting guideline will remove your issue.
Frequently Asked Questions (FAQs)
Why Is My Cobra 29 Antenna Light On?
Your Cobra 29 antenna light could happen because of unadjusted antenna warnings. Also if SWR is over 3 your antenna light might get on. So, adjust the antenna warnings. For this, you need to unscrew the cover and adjust some wires. If you’re new to this, consult an expert.
What Causes A CB Radio Not To Transmit?
The possible cause of a CB radio not transmitting is its fuse has blown. Also, the power cord could be a fault. So, make sure to check all these before adjusting any wires. The fuse must be in place and seated properly. Sometimes the power cord can get burned so be careful with that as well.
How Do I Know If My CB Antenna Is Bad?
You can tell if your CB antenna is bad by measuring the resistance of the circuit. The resistance should be little or null. The circuit should also be continuous all the way to the antenna. If you find any resistance or no continuity, the circuit is damaged. This means your CB antenna is also damaged.
What Does Red Antenna Light Mean On CB Radio?
The red antenna light on a CB radio means the radio is transmitting data. If a red light pops up when it’s not transmitting, that means SWR is above 3. Except for these situations, the antenna light is always green. Another reason could be an improperly grounded antenna.
Final Words
This is the end. Now you have the Cobra 29 ltd classic troubleshooting guideline. Carefully go through this.
Always remember to follow the service manually while setting up the radio. If you’re not confident enough, don’t pull out any wire.
That’s all for now. Until next time, keep fixing!
