Question about Cobra Radio Communications
I want to turn the wattage up what can i do?
Why does everyone want to turn up the wattage. the most you can legally put out is 4 watts.leave it as is and get a small 100 watt linier amp and you will smoke em.

deweyp, hi, if you are wanting to turn the power up some on the radio, do this; tune L4, L5, L6, L9 for
maximum RF forward output. There are 2 versions of the radio, and both are listed as 510xl. If you are wanting to expand the freq's or add channels, then no, there is no mod for that radio. If your going to tune the radio for more power, make sure you have a power meter to watch the output. It is preferable to tune into a dummy load so your not broadcasting over the air. You tune the radio for peak output, using a steady awwww sound in to the mic. Just be careful as that radio has a fairly small driver and final transistor. Don't want to let the factory smoke out of it,,,
Here is what the little variable adjustments are for and what they control;
VR2 TX Meter
VR3 RX Meter
VR4 RX IF Gain
Hope this helps you out, let us know,, Mechanic

If you look on the solder side of board you shoud see a straight line of 5-7 solder joints, look on the other side the audio vhjp is a bmack thin retangular ic chip. Not to worry you wont hurt anything by doing this. Its an old cb tech trick to test audio chips.GOOD LUCK.
Oh one other thing does the radio have same same problem in either vehicle? A insulating washer on the antenna bracket can cause this also,
