Icom IC-738 (IC 738 IC738) transceiver mods reviews software and diagrams

1. Remove power & antenna.
2. Remove screws & rmove top & bottom covers.
3. Swing PA Block saide & fold down the front panel ( you may need to unplug the Q1 Cable. Note connector orientation )
4. Locate D15 and move it over one position to the right ( of its original position )

After I have tried the information from Mods. it only tell to move a diode d15 one place to right.
But I can tell it is to place 14 which is left, -if followed as told now, one place to right, it means place 16 and that makes it to a japanies version.

extended TX - move D15 to Place 14-
diode is placed on the backside of the frontpanel
