[CQ-Contest] RELAY SWITCHING

[Herbert Schoenbohm]

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.
