somewhere on this forum was a list someone put up on peaking and tuning the magnum 257 to get the maximum power and set the signal meter and the power for fm and sideband. I have looked all over but i cant find it. thanks

Is this what you're looking for?

RV-1 S-Meter Signal Strength
RV-4 AMC, AM Modulation
RV-8 RF Output Meter
RV-9 ALC, SSB Modulation and Peak Power.
RV-14 FM Carrier Power
RV-16 AM Carrier
----------------------------------------

The site that Tech808 suggested is a very good one.

my radio is already modified and the other site at cb tricks is not what i what looking for
what kcogxz posted are the pots i need to adjust but in one of the areas of this forum i think was in product reviews it told you how to peak the magnum 257 to get it to dead key at 10 watts and swing to 30 watts. i have looked in all the areas but cant find it. i think it may have been removed and i was hoping it could be listed again so i can get my radio peaked

It is in the subscriber section. Tech 181 did a very good review on the 257. Try this
