OK guys - rather than reply individually, let me try to pull everything
together in one message.
In a previous effort at FT8 I followed the standard advice to set the
power slider in WSJT-X (on the lower RIGHT side) so that my K-3 showed 4
bars on the ALC meter, just below the threshold for ALC starting, and
that seemed to work fine. Then a technically-qualified local ham showed
me spectrum analyzer images of a K-3 at 4 bars versus at no bars, and
the difference was startling - the no bars signal was clean and narrow,
while the 4-bars signal looked like some of those SSB sigs we hear
during contests, wide and with many artifacts. I am not going to
identify my source here, but I'm fairly sure he reads this reflector, so
maybe he'll join the discussion
Anyway, I'm kind of at sea - WSJT-X works fine with no bars - I've
finished 12 and 17M, as well as digital DXCC in the last few weeks,
following his advice. But the hunting typically takes almost 20 seconds
of transmitting - roughly 1 1/2 FT-8 cycles - to reach full power - and
happens every time I change bands, which puts me behind the curve if I
switch bands, see someone I need, and have to spend 1 1/2 transmit
cycles getting up to full power before I can call him effectively.
