QRP: slowing down the power again

QRP: using only 1,8 watt

Working conditions: 
Rig: microBITX
Ant: Off center feed dipole, 20 meters long, folded and linearly loaded (on a tree). 
Ant tuner: Kenwood AT-130
Power: 1,80 watt (1800 milliwatt)

QSO during last year of very soft activity on 21 MHz (almost some minutes during the weekends; never in the evening or during the night).





 I use the microBITX from about one year. On 15 meters, the power given is of about 1,8 watt (1800 milliwatt).  I thought the output power was of 5 watt, but when i measured the output power i realized that it was of only 1,8 watt.


During the last year the band was often closed, so i worked mostly on 40 and on 20 meters. We are during the minimum of the solar cicle, and so this is what we can expect. But last week i extracted the data from my database, and elaborated them. The strange thing is that generally when i had the QSO, it was not difficult, may be for the low noise of the band.
My favorite mode is CW, but also USB is valid, during contests.
