Following on from the last post, I decided to carefully look at my WSPRlite unit and test its power output against that set, using a calibrated oscilloscope.
The results are as follows:
At 14MHz:
200mW set: 176mW measured output
100mW set: 114mW
50mW set: 57.6mW
20mW set: 23.6mW
10mW set: 11.8mW
5mW set: 5.2mW
I haven't conducted a comprehensive test at other frequencies. But, I did notice a drop to 144mW at 10MHz when 200mW was set. I will look at this in more detail in the near future. By 7MHz, the drop was to 168mW, rising to 189mW at 3.5MHz.
