20 Most Recent Cobra 19 DX IV CB Radio - Page 5 Questions & Answers

Go on a channel where people are talking and when some one stops transmitting key up and say, "breaker breaker, can I have a radio check please?"

that is how you call for a radio check to see if people can hear you.

breaker breaker, or break break means kind of like, "excuse me, I would like to talk on the channel please."

If they hear you the will most likey say, "its working." or "Checks in the mail." You can then ask them after that how the radio sounds.

Also make sure your mic gain is up.

If you get no response then there may be another problem. Make sure you followed the instructions that came with the radio on how to tune your antenna for best SWR. This is important.

Check the in line fuse to make sure it is not blown. I would also check the cb pa switch

Too much Feedback will result from running P.A. audio to the CD Player speakers.

That post was meant to be the solution, sorry.

try a different mic.

have your SWR checked...which is your antennas..make sure its matched to your vechile.Have you tried an external speaker?

switch 1 pin to 2 and 2 pin to 1. and 3 pin to 4 and 4 pin to 3

Some times knobs go bad. I have a funky knob on one of my radio's. When ever you wiggle the knob it just makes awful noise.

If this is a similar problem, you can try to clean the knob with electrical contact cleaner.

If that doesn't work you my have to replace the knob.

As for the switching to 19, it could be a byproduct of a short in the knob.

turn the RF gain all the way up and leave it there. Also turn the squelch down until you hear white noise, then turn it up just until it goes away.

RF gain is how sensitive your receive is. The higher it is, the more range you have. There really is no need to turn it down ever, unless you are trying to not hear some one out in the distance. Normal operation, RF gain should be all the way up.

Now squelch is used to quiet non signal noise. Like white noise or interference noise, Or other radios with a really weak signal that you can't hear completely any way.

You just want it so it just quiets the fuzz noise. Depending on background interference and the amount of radio traffic, the may have to be adjusted to silence the noise you don't want to hear. When a strong audio signal is received, it will break the squelch, the higher the squelch is set, the stronger the signal needs to be to break it, otherwise it will silence it.

if you hooked it up backwards first, you blew the protection diodes in the radio. they need to be replaces.

You need to unsolder the old one and put in a new one.

You need to make sure you don't hook it up backwards ever.

Check fuse too!

Open the bottom cover, watch the wires from the speaker as not to pull them out.

Look towards the back right of the radio for a black diode that is burned up. If you have 1 that is burnt, then go to radio shack and get a diode 1n4007. then replace it with that.

And, be careful next time you hook it up.

Tweek and peek is minamal on that radio, Finals can not be adjusted but can be replaced with larger ones and the swing limiter needs to be either rebiosed or clipped. Do not try to do this yourself with out the right equipment you will just make it a noisy mess.

dm1 next to transformer

I would definitely take it back for a re check. If the radio took a good bump perhaps it can cause it to drift off frequency. Turning the channel while holding his mic keyed does nothing but just throws a dead carrier. No value what soever. RF Gain is just to improve his reception by either lowering or raising the sensitivity of the receiver of the radio. Squelch is to silence the hissing sound you hear when no one is talking. Care must be taken to not to adjust too much or you wont hear anybody. It wont help his transmit audio at all. Recommend you get another Radio Check from someone else. He could be pulling your leg saying you don't sound good. Best regards and hope this helps some......................John.

not a good idea to do it yourself you need the proper equipment to do the alignment you must know what part is the transmit and what is the recieve.

Have you ever checked your SWR's?

It sounds like your final transistor is fried. If you have too high of an swr, you can fry your final.

I recommend either taking it to a cb shop usually you can find them at truck stops. Or try to put it back to looking like you didn't do anything too it and then try to return it.

It is important to set the antenna properly for SWR. Refer to your manual on how to do this.

You can try to replace the final transistor. Not sure off the top of my head which one that is.

the problem is in the antenna cable. the lenth of a antenna cable must be divisable by 3. try replaceing cable with a 18 foot cable that should fix the problem.

You might try running an insulated wire and ground directly from the battery.

There may not be much chatter (people talking) in your area. Try to find a local CB friend who may introduce you to the CB world.

The 2 antennas idea does not increase input or output, in fact they (without additional high powered equipment) cancel each other out. Most CBers will only connect one antenna and have another installed and not connected but only for cosmetic reasons. Its only once a very high power threshold in reached that 2 connected antennas will be a benefit. Those are the ones that there output bleeds all over other peoples TVs and AM/FM radios.

Good luck
