SOURCE: modification of frequency output of uniden pro 510xl

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;
VR1 Squelch
VR2 TX Meter
VR3 RX Meter
VR4 RX IF Gain
Hope this helps you out, let us know,, Mechanic

SOURCE: Uniden Pro 510xl can send but not receive

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,

Why does the Uniden 40-Channel CB Radio (PRO505XL) "PA" acts like an extra external speaker!


nothing,thats what its supposed to do. Don't try transmitting on pa though you will blow that speaker. the type you would need is a bull horn speaker.

Why doesn't my radio operate in the "PA" mode?


Some radio's do this (specifically Uniden) for some unknown reason. Ideally you plug a speaker into the PA output and when you switch to PA mode, the CB transceiver part should turn off and only your voice should come out of the PA EXT speaker to make it act like a personal megaphone.

because when you switch to PA it is because you are on the outside of your vehicle.When another party calls you ,you can hear them and then go to your vehicle flip it to cb and talk to your party.
