Cobra 19 DX-IV

Post by RodK »

I have two (2) 19 DX-IV CB's that receive just fine, but the transmit audio is VERY distorted.

I've checked the Forward power (4-Watts) and Reflected power (0-Watts) so the antenna checks fine.

The supply voltage to the radio is within specs (14.1 VDC). These findings are the same with BOTH vehicles.

So I had the department buy two new ones and they are doing the same thing. Even on my work bench they sound GREATLY over modulated!

Has anyone else experienced this problem? I am going to take them to the dealer and have him check them out as well. But I was wanting to hear if anyone else experienced the same issues.

howdy, guys, i have a dx 19 iv and am getting 19 watts on a swing on a dosy 4002 psw. there is no distortion with my radio. maybe the dates of assembly have something to do with this. maybe its a run of bad boards,who knows? you may be able to fix this. maybe(i like this word,does it show?) the pre amp or the final is being over-driven? good for my guitar amps, bad for vocal audio. had to add my 2 cents. adios,amigos!!!!!
