I'd already done that. I could turn both RV1 and RV136 back and forth and not see any change in the current. But, you said "You should see a voltage at the gate of the IRF when you turn the bios pot a little bit." so that's what I was checking on.

If my meter is on 10A, then I get .01 on the readout on idle. I get .02 when I push PTT. Adjusting RV1 and RV136 counterclockwise to open it or clockwise to limit does not seem to make any difference. Speaking into the mic doesn't cause the amperage to move. I tried with my own mic plugged in, then wired in the electret mic included in the kit when that didn't work and it didn't cause any change either. Measuring from a dummy load inserted in the cable, I get no amperage, no voltage....nothing there either. I get a hiss in the speakers when I turn it on as if it is receiving static like normal. When I click PTT I hear a pop. The speaker goes dead like it's supposed to while I transmit. Then when I let up the speaker comes back on. But, I'm seeing no change in voltage or amperage.
