DTB set the radio up, I would guess he's got the modulation set; although its been several years since he's been in this radio. I run the mic gain around 12 noon...
Why?? Four 2879s are rated at 150 watts PEP each, for 600 watts total...unless I missed something??? I try to run close to that to prevent too much splatter.
I have a pretty new Chevy Tahoe running a Texas Star 350 wired directly to the battery, no issues what so ever, Wilson Mag mount with a Yeticom Optima driving the snot out of the amp. Both my feeds, ground and power go to the battery not just the power.
