Dan,

For testing purposes, you can try connecting the SP-110 directly to the ADC0 input on the TX board. Then, on the RX software, comment this line

Code:

       SolarRad = map(RX_Data[2], 0, 1023, 0, 1600);              // Using OP - Formula outputs an integer, between 0 and 1600 W/m2

and uncomment the next line.

Code:

       //SolarRad = round(((RX_data[3] * (1100 / 1024.0)) * 5);   // Not using OP. Sensor connected directly to ADC input

result should be like this:

Code:

     #if (Solar_Sensor == 2)      // Apogee SP-110: Self-Powered Pyranometer (Solar / UV interface R2= 4700 Ohm)
       //SolarRad = map(RX_Data[2], 0, 1023, 0, 1600);              // Using OP - Formula outputs an integer, between 0 and 1750 W/m2
       SolarRad = round(((RX_data[3] * (1100 / 1024.0)) * 5);    // Not using OP. Sensor connected directly to ADC input
     #endif
