? People purchase automobiles that will go faster than the 65 miles per
hour speed limit. My wife drives one that will go 3db faster. The
8171/4CX10,000D can be run at 10db gain or 20db gain. However, amateur
radio operators should use no more power than is necessary to
communicate. I would like to see one dx-pedition where no one who is
received at more than an S-7 signal level on a calibrated S-meter
receives a QSL card.
