MI CB COBRA DX-19 IV when someone ear me say i don t ear you well sounds like bad voice or no good my voice..

SOURCE: 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

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.

If this doesn't help, please reply here or shoot me an email at:

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.

SOURCE: Cobra 19 DX IV out of frequency

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.

SOURCE: I have just bought a new Cobra CB DX IV (i think)

truckers also like it to have 300+ watts,, and don't tell them what you have and see the difference. lol

also the stock mic's are tinny sounding. trade it off for a good power mic like a cobra 75 $17.99 or any type of echo mic $35 i think.. those will make it sound like a big radio.., also check the SWR's !!!!! free at any cb shop to have them checked .. we don't charge unless it needs parts.
