David - For what its worth, I get similar results when I measure power with my DL1 and Fluke meter. With my Oak Hills watt meter, I get about 3.5 watts on all bands. 73 - Rick - K7MW > (( V * 1.414 ) + 0.15 )^2 / 49.5 => P <-- taken from the DL1 instructions > (my DL1 tests at 49.5ohms, hence the divisor is not 50) ://www.elecraft.com/elecraft_list_guidelines.htm
