Remember that after doing this mod to the Field OR standard Mark V, that you
MUST have the optional TCXO installed and Menu 5-9 set to 2.4 to Legally
operated on 60M.
just thought I would mention it as no one else has.

surface with the front of the rig facing you. There are three boards
visible. One is the "Control" board on the left side, the "AF" board on the
back right side and the "IF/Filter" board on the front right side. Go to
VR3003 on the AF board and turn it clockwise. It's marked "RF Power" (I
think it was). Fully clockwise gives you 190 watts in the CW mode on 14200
kc, 200 watts on 1845 kc and 180 watts on 28400 kc. Of course connect an
antenna with low VSWR or a good dummy load.

Also, do you really get 200W out? Need a beefier ps?
