Or maybe get better receivers. I go out of my way to work weaker signals on CW and try to answer those calling CQ on what are known as "QRP frequencies." Rarely find anyone running 5W who hears me as well (running 100W) as I hear them. If I turn it down to 5W, they don't hear me at all. My antennas are fine. This may be a "local noise level" issue, and I can't help solve that one. But if it's not, I think a lot of QRP rigs either have lousy receivers or the operators aren't really listening to resolve signals as weak as theirs are and are likely missing lots of answers.
