RE: scanning 5 antenna input ports
I ended up building a swr circuit and just send a 433mhz signal .
I know 433MHZ!!??
It was a small transmitter I have laying around Gives me a real nice
return single with an antenna on line and almost nothing with no antenna. Now I have to turn the return signal I can control.
Going to use the Arduino to analog read the signal and give my a digital output. This gives me the control points I need.
I can also use an external Analog to Digital convertor like the PCF 8591 but first going to use the Arduino to do the A/D conversion.
Thanks for your help Ed NW4K 73's
