Question about Cobra 19 DX IV CB Radio

1 Answer

Cobra 19 DX IV

To your answer on my first question, the power meter says it is putting out all 4 watts. I even bought another cobra 19, hooked it up and it sounded exactly the same, garbled and unreadable. The SWR is 1.3 and the 4' firestick is not tunable. There is something else going on here. The unit is grounded to the body, power lead directly to battery. top of antenna is even with the top of vehicle but out on front bumper so the top half of antenna is clear of obstuction for several feet. Are these CB units just totally chinese trash?

No, those radios are good radios. I have one just for setting swrs on antennas.

First, I went back and read your last question. You said you have a nylon washer on top AND bottom? Did you mean one under on the top and bottom side of the antenna mount? You only need theone on the top of the antenna mount, which stops the antenna itself from being grounded out. Having one on the underside stops the outter part of the stud, the one that touches the outer screw on part of the coax from being grounded. Without that getting a good ground, you have no groundplane, which will cut your tx/rx to a max of 2 miles. Also, how close is the two setups. Many times, if two vehicles are setting next to each other, you will not receive or transmit properly, just get a nasty garbled with a hint of a squeal.

How far will a cobra 19 cb reach

This is a tough question with many variables power, antenna, weather, terain, other radio traffic and interference on channel and reciever sensitivity.
The answer/guess roughly 2-8 miles depending on best and worse conditions.
This is one of your lower end cb radios but has a good receive sensitivity of the money.
This might be a good resource for any other questions you might have

Be aware that most cb radios that Truckers talk on are actually 10 meter "export radios" that are illegal by FCC standards. They put out far more than the legal 4 watts that radios sold in the US as cb radios do. This is not to say that your typical cb is not modifiable to high rf power levels but not to the degree that the exports are.

I have my radio hooked up in my jeep and i can hear other people talk but it seems that they cant hear me talking. Its all hooked up right. i checked to see if there was a tuning thing on it and there...

Turn up "MIC GAIN" also check and see if it keys up full scale 4 watts on output meter. If that doesn't do it change MICS. Go for a power mic by cobra that runs off say a double AA battery. It may be conditions also or your out of range of persons. check Antenna,Swr reads (should be 1.1 to 1.5)on a Radio Shack meter. Try it all.

Cobra 19dx iv when i key up it swings all the way to a 9 is there any way to set swr,s without a meter

Just buy a factory built antenna/(it should be close) Buy you a magnet mount RADIO SHACK job(works). If your indoors buy ANTRON A99(set at 1.3 SWR factory). If it keys 9 db then that equals 4 watts output thats OK.

Wanting to put a cobra 19 dx IV cb radio in my truck and i need to know how do i connect the powersource to the fusebox

If I were you, I'd hook the power source directly to the battery. There should be a plug like rubber thing near your brakes. Take that out and run your wire from the cb radio to the battery. This way the truck doesn't have to be turned on to talk. Just make sure that you turn the cb radio off each time you use it or you'll drain the battery.

Just bought cobra 19 dx and wont even turn on

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.

CB transmission

Hello 64driver,

Make sure the radio is grounded properly and that the SWR is around 1.2:1, 1.3:1 is good but try to get it to 1.2:1. Also take a power output reading while keying the mic. To do this with your power meter put it in-line with the CB and your antenna and key the mic you should get about 4 to 5 watts PEP. If this is the case your unit is putting out the proper power level, if not have the power amplifier checked by a qualified repair shop.

I hope this helps
