I just did a quick calculation of QSLs received versus total QSOs and the answer is an almost unbelievable 71.6% in LOTW and 80.4% in QRZ. This is based on QSOs since 2013. Even when I was a rare DX operator, I never approached this. LOTW has done a lot to increase QSL returns, as has computer logging that automatically uploads to the various QSL sites. I really don’t chase awards any more, but it’s nice to see how things are going, even if I’m not really using the data.
