I am easily tempted to use more power than needed. They don’t hear me with 5 watt? I crank up the power to 20 or 40 watt. But more and more I found out that it has seldom to do with power to be heard. Antenna and propagation is more important. A dose of luck is maybe needed, or the effort of the opposite station to pull the signal out of the noise. But more power? I don’t know. I don’t have to convince my QRP friends that it is more satisfying to accomplish a QRP qso. It's just so.
Now with my new antenna, the MV-5+3 multiband vertical, I can work easily QRP without any problems, when I compare it with the Falcon 250B vertical. It was hard to be heard with QRP when using the Falcon; I think the efficiency was poor. The MV-5+3 is quieter than the End Fed Wire, 12 db. The SNR is very good of the Sand Piper MV-5+3.
Back to power. From now on I decide to use 5 watt power or less for all modes. I just worked RV9JR (4200 km) with 5 watt bpsk31 on 20 meter. I add the /QRP to my call sign, I think they are willing to work a QRP station more than just another PA station. A QRP station is much more special I think.
