...I've been after our local club to do a QRP field day but they show no interest. 100 watts is as low as they want to go...
This is at least the second year this club has tried QRP. Most of the participants are not regular QRP operators
and took a rather relaxed approach, often with somewhat compromised antennas that they normally use on
their RV. In another corner was the ARES trailer that had reasonably good antennas (though they could be
better for 40 and 80) and operated SSB. Both groups probably would have easily made more than 2.5x the
number of contacts at 100W. Certainly it would have been much less frustrating for the operators. (This
was not as organized as the Field Day operations at most other clubs I've seen.)
But I don't think I could have worked enough more stations at 100W to make up for the point differential.
Possibly: 50 QSO's per minute would be hard to maintain without running out of stations, but I might have
been able to hold a frequency and run stations with a good antenna.
Certainly for QRP you want to use the best antenna you have space for. We had room for an extended
double zepp on 80m, and many antennas weren't even full sized for 40m.
