Bozzman,

Mod Limiter - R249 (removal NOT recommended)
Modulation - VR14 (Set for just under max)
AM Power - VR13 (Set for 4-6 watts deadkey)
SSB Power - VR12 (Set for max)

You can read my full review on this radio elsewhere on this forum.

Wade,

White wire should go to rear side of TP8 which is the clip that holds the mirror board (not foil board) in place. The mirror board as it is called is in front of the final and driver. It's about 2 inches long and a half inch tall and is held in place by three clips.
