Alternate fan mod for IC-7000
!! IF YOU ARE UNSURE ABOUT PERFORMING THIS MOD DON'T!!
!!IF YOU DAMAGE YOUR RADIO YOU ONLY HAVE YOURSELF TO BLAME!!
I have performed this mod on MY OWN radio without any adverse affects and my LDG AT-
7000 atu still works as it should.
Before this mod after been turned on for an hour or so the temp meter on the radio would
show around 50% on the scale (7 or 8 bars), after the mod the temp meter shows around
25% on the scale (4 bars).
First remove the top cover and remove the fan from the radio,
take a 100ohm resistor and solder a length of wire to each end and cover with heat shrink
tubing. Cut the red wire to the fan and attach one of the resistor wires between the two
halves and cover with heat shrink tubing.
Next follow the ORANGE wire from the ATU molex socket on the back of the radio to where
it is soldered on to the DDS unit (top right hand corner at the back of the radio) and attach
the remaining resistor wire to this point, position the resistor and wires so that they look
neat and tidy and then refit the fan and the top cover, mod is now complete.
