Yes I also noticed that. Most of the test results
were at 2khz spacing, but some were run at 3, 4 or
5khz spacing. If you look at the wider spaced tests,
they occur with older radios. I assume that the
synthesizer phase noise in these rigs made narrower
testing impossible because it was noise limited. I
could be wrong, though. Still, it is a much more
appropriate test than the 20khz spacing that QST used.
I would also like to see Rob Sherwood test a few other
rigs, like the Yaesu FT100D and FT767, Icom 740, and
Kenwood TS690/450.
