This Arduino 8X1 is superb at controlling a DXE 5 KW box mounted at the
base of the tower with CAT 5 cable 150 feet long. The Arduino is in the
shack driven by the AUX output of the Ameritron RCS-12 which provides
either automatic BCD selection from the Icom or manual selection by the
RCS-12 push buttons. If you don't use the RCS-12 a small rotary switch
with a wall wart will work. You can't beat the price.
