[With regard to the need for instrumentation]

very close, but with the added instruments, one can achieve a higher degree
of confidence in those parameters. "
People entering QRP competitions like to be certain they are not putting out
any more than the 5 watts allowed in these activities. Hence, the
biggest need
for a wattmeter. I rely on the K3 default settings, and will check
them if and
when I obtain a wattmeter I can use as a standard.
A signal generator with calibrated output levels (such as the XG-2) can
also be used
to extrapolate measurements of a receiver's minimum discernible signal
(mds). For me,
that was more important than accuracy in s-meter readings. I also used
the XG-2 to
make some nice frequency plots of various combinations of roofing and
DSP filter,
with the aid of the K3 Filter Tools software by KS7D.
