I used the plastic green tool provided but just modified a bit... I cut it off about 1/8 inch up and then diagonal cut on the sides to form a nice "screwdriver" tip and it adjusted my 8 inductors just fine. (Of course, when I get my 4 band board, will probably be looking for another tool for the variable caps.) Duane. K7ZH K1 # 1103 K2 # 2516 (under construction)
