With skill, and with the best QSK radios, ABSOLUTELY! Especially when the
DX is working split! And remember, good operating is about SKILL,
COURTESY, and GOOD JUDGEMENT.
There are differences between the performance of QSK radios, mainly how
quickly they switch (or how closely the receive gaps dits and characters
resemble the actual keying "makes"). Example -- let's say there is a 10 ms
gap between dits or characters at a given speed. If switching eats up 8 ms, it
will be hard to hear much between dits. But if switching is only 1-2 ms, you
can hear a lot more.
I can vary the QSK time with the K2 to make it more "slient," but that
increases the switching time and I can't hear between dits. I set it for the
minimum time, which allows me to hear more. It's a bit noisier in my cans, but
it allows me to be a much better operator.
Running QRP in the WAE this weekend, I needed to do a lot of repeats, but
QSK allowed me to stop sending when the other guy came back to me. I
heard a fair number (25%?) of guys who obviously couldn't hear the other guy
coming back, and it slowed things down a lot. (you notice this stuff when
you're running QRP, because you have to do S&P and wait in line for others
to finish. It's painful when one or both of the folks you're waiting for don't
have
QSK, because it takes them longer to finish a QSO or recover from mistakes
or poor copy.
