Please forgive the bandwidth, but I always feel compelled to rebut the
naysayers.

I have consistently said that my tests are for digging CW weak signals
out of the noise in a band with no strong signals nearby. Contest
conditions are an entirely different story which I don't test for.
Regarding the 150 Hz BW of the 100 Hz Orion DSP filter with broad skirts,
that doesn't explain why it performed so miserably in my A/B tests. It
was even worse than the FT-1000MP when using the MP's 500 Hz xtal filters
without the 60 Hz DSP filter activated. Ten-Tec's so-called "white
paper" about the programmable AGC does not explain the Orion's extremely
poor weak sighal performance either.
