I'm just wondering what you are trying to achieve?

well i live around high voltage pwr line and a cb shop buddie said upgraing the caps would cut out alot of the noise and im thinking if i do upgrade the caps wont that cut out or limit my RX or TX?

Just enjoy your radio as it is. Your buddy is an idiot.

What most people are talking about is that some radios only have 16 volt rated capacitors and that is running a little close to the normal operating voltage of about 14 volts especially in a mobile where it may be even slightly higher. They sub them out for 25 volt devices. If the radio is quite old some capacitors may be below their rated values and should be replaced but just to do it because someone said so is, like m42duster said, idiotic.

I asked my fav tech about if the 1000uF 25 volt caps needed upgraded in my Ranger TRE-936ffc and this is the reply I got. "The 1000 uf caps are generally fine unless you end up getting a ton of electrical noise through the power leads."

On a new radio, that is pointless.
