Pro510XL schematic
 

Can anyone help me out with a schematic for a Uniden Pro510XL. I only need
the audio amp/mic input section. I'm going to try to remove the DC voltage
to the mic and use a power mic or something. This should do away with it's
worst path for RF feedback.

Thanks,

Chris

It's not likely that you are getting RF feedback from any DC voltage in the mic
cord. At CB freqs, the coiled mic cords make excellent chokes and prevent most
RF feedback from a mic. And almost all radios have caps and/or chokes to shunt
any RF that may sneak through the connector.
