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


Sorry, but each rubber duckie is cut to a specific frequency, with the actual antenna windings sealed inside the rubber/plastic outer shell. Because of this construction, there is no adjustment feature.

you should have check to see if one transmitted and the other received before you did all this then there would be no problem of this nature . Its probably not the IC but a resister or a diode.

try turning you radio power down to 1 watt and see what that does .the asskicker 100 watts is being overdriven by the radio power and its coming out sounding horrorable . How many watts does the radio put out now? the lower the better like I said in the begining 1 watt is best with a box.

Get a SWR-PWR meter to put on the line between the radio and antenna to see what it is doing.

Cobra 19 DX IV... | Answered on Dec 02, 2014


The SWR meter on the radio is some what accurate, you might want to use an external meter. First thing you do is get a pencil and paper to write down the readings. On your meter you will notice it says FWD and REF. Set your radio on channel one then set your meter on FWD , key your mic , adjust the meter to the check line , then switch it to REF and do the same . Now write this number down. Switch to channel 40 and do the same then do the same on 19.If you have a final reading of 1.5 over the band then you are ok but if its higher on 40 then on 1 you have to shorten the antenna , if its higher on 1 then you have to lengthen it . Continue this until you have a satisfactory reading.
