I go from QRPp to QRO. I've been working QRP, from time to time, for over 40 years and find it very rewarding when I work DX with only 5 watts. When I purchased my KX3, I decided to work 100 countries again. It only took me three months to do so. I did not operate during a contest to get them.
Remember the Rockmite? Those little guys were only 1/2 watt. My friend, now a silent key, worked a VK station with CW and he lived in the eastern part of PA.......with the Rockmite.
At only 5 watts out I've gotten a lot of signal reports were I was 10 db over S9.
Like someone posted a comment on one of the forums, pertaining to QRP, "You are always S9 somewhere. "
