 Why QRP
QRP is defined as not more than 5 watts output CW or 10 watts PEP SSB.
To operate with a standard rig, turn the output down to minimum.
Here's the math.....
10 watts compared to 100 watts = 10dB reduction
5 watts compared to 10 watts = 3 dB reduction
So total power reduction 10 dB + 3 dB = 13 dB reduction
One "S Unit" = 6 dB, therefore 5 watts is only about 2 "S Units lower hen 100 watts.
