[Elecraft] K3 in the CQWW contest

[Ron D'Eau Claire]

Even with a lesser receiver, I allow plenty of frequency spacing between
myself and another station on CW, recognizing that the other station may not
have superb selectivity. Around the CW QRP frequencies, I often allow a full
kHz and several hundred Hz on other frequencies.

When getting ready to transmit on new frequency I always open up the
selectivity before sending "QRL?" so I can hear if anyone nearby responds
who I would never hear with less selectivity. Besides, as others observed,
other stations are often not quite on frequency and the CQing station using
narrow selectivity may just keep heating the aether while others are trying
to respond just outside of his bandpass.
