Question about Cobra 19 DX IV CB Radio
Me and one of my buddies bought one of these from walmart, we wanted something cheap when we go off roading. we got them all hooked up and he came by to see if everything is working ok. when i transmit it is crystal clear on his but when he transmits it doesnt sound real clear, it does have any back ground noise and you can understand what people are saying if you listen close, but his sounds like your on the phone.we havent tuned our antennas & i have tried searching to see what effects and out of tune antenna can have but just got stuff on how to tune it with a meter. so is my cb messed up or is his? is it the out of tune antenna causing it, but his is clear with no tune eithe? what could it be? thanks and sorry for the long story
First off, that radio will not transmit very well anyways. but for just off roading it should suffice. You really should adjust your antenna's both of you. First off this is almost definitely the problem if you can recieve but not send. Also if you use the radio without a properly adjusted antenna it will destroy the radio over time, sometimes instantly. pick up a cheap SWR meter and follow these steps: Plug the SWR meter into the radio, and the antenna. Start on channel 1, the meter should have a switch with 2 settings, one for adjustments and one for reading. Key up (hold down talk button on mic) with the switch in adjust mode and adjust the knob until it reaches the adjustment marker. flip the switch to reading and key up again. Your goal is to get this reading as close to 1.1 as possible, anything above a 2.0 will damage your radio. if the reading is within range repeat for channels 20 and 40. good luck!
