That did the trick! I looked closely at the joints for L1 and L2 and noticed that one of L2's? pads (nearest IC3) wasn't fully flowed around the wire. It passed the continuity check when I assembled the board, but it must have been marginal. I reflowed it and the others on 80M just to be sure, and am now getting 7.1w on 80m.
Thank you!
