[Elecraft] K3 in the CQWW contest

[Guy Olinger K2AV]

Are you recommending in a CW contest that one not engage in running if
one cannot find a space with an open kHz above and an open kHz below?
:>)

Common contest practice in recent decades is 500 kHz between signals
regardless of folks without filters. And that seems to be squeezing
down to 400 and narrower, which some folks derisively have called the
K3 effect.

Last weekend I spent nearly 3 hours 350 Hz below HG1-, who had bad
clicks, and managed it with the K3's extraordinary DSP NB. He parked
up 350 after I had been running on the frequency for nearly an hour. I
didn't move and made many Q's on the frequency with him up there.  I'm
sure he thought I would go away, and I probably didn't bother him at
all because my K3's transmitted signal is devoid of key clicks.

For casual operation I agree with you, but in the contests, it's just
p**ing in the wind.

73, Guy.
