Adam, VA7OJ/AB4OJ's IC-756Pro User ReviewĪdam, VA7OJ/AB4OJ's IC-756Pro/Pro II User Review If you can't find out the version of your 756-PRO (#02 or #03), look at the topside of the box. Trouble to find the diode-row ? It's about 1/2 inch located under the CPU. R R R I I I X X I I X X I X X X after version "2" mod. R R R I I I X X I I X X X X X X after version "3" mod. R R R I I I X X I I X X I I I X diode-row IC756-PRO version "#03"
When you have a version "#02" : remove diode 3751, 37 ! You have to remove 3 small diodes located on the left side of number "3751" (diodes 3752, 37) when you have a version "#03" Icom IC756-PRO. You can see on the right of the row the number "3751", that diode is already missing, hi. You have lift the dsp-box (with care !) out of the mainboard.Īfter removing the dsp, you can see a row of diodes with some spaces. When you removed the cover and you have the backside of the 756-PRO facing you, you can locate the dsp-box on the left-side (the shiny-box). You have to remove the bottomcover of the 756PRO. You need a very fine solderiron to remove the 3 diodes from the mainboard!
