![]() ![]() After the loud P passes through the circuitry, when the ‘aw’ comes through, the audio is still very low, and the radio ‘talk power’ is also low Notice how the sharp ‘P’ sets the audio limiter into motion, which lowered the radio audio level sensitivity so the quick rise of the P did not over modulate the transmitter. Now, let’s speed up the recovery time a bit and say ‘paw’ again.įigure 2 shows what the audio level sensitivity would look like with a very fast recovery time. You will see that the sensitivity was reduced by the P as before, but the audio level recovered quickly enough to get some of the AW to 100% modulation too. That is what we call increasing ‘talk power’. So, why do we want more ‘talk power’? Your CB receiver sensitivity is measured in what we call ‘signal to noise radio’. That means we want maximum signal above noise for increased listen ability and an overall better copy. By increasing your talk power, you are increasing the amount of signal to noise ratio in everyone’s receiver. ![]() You not only sound ‘louder’ to everyone else, you also sound ‘stronger’. Your range is also increased in this manner by being louder than background noise on the channel. ![]()
