Actually, Wayne, you have it upside down. The K3 topping Rod's chart
simply validates his testing methods.

It's not just vhf contesters who have a problem, we also have 59+60 to 66dB
signals from broadcast stations on 40m (and don't forget those nasty
sidebands)
-10 to -5dBm is not unusual from a high dipole.

Did Rob comment on pops and transients generated in the AGC and DSP?
That was the subject of his presentation at Dayton 2007, where he gave
many examples to show that "New IF DSP designs [can] seriously
exaggerate transient noise on weak signals... Some DSP radios make QRN
much worse."

Yes, the Orion (II) is a "little" unpleasant to listen to unless one perhaps
adjusts RF gain down. I enjoyed the excellent filtering on the Orion II when
comparing the modified FT-1000D and Pro III, but the Orion II felt "unfinished"
for the year and a half I had it. Yes, can maybe blame the ag
FWIW, my initial listening isn't hearing much difference between the Orion
and K3 on transient response. So far, static bursts are sounding pronounced
on both radios to my ears.

I certainly felt that way when listening on the Orion. The AGC was never
right.
