First I'd say that a roofing filter has little to do with actual receiver IF
selectivity. In other words, the roofing filter is pre the DSP selectivity
which would typically be less than the BW of the roofing filter. Today's
receivers develop their selectivity in the DSP system.
In the referenced video, I could not discern the DSP selectivity of the K3
or the FT-5000. The Orion II BW is 520 Hz.

Here is a You Tube comparing the K3, Orion II, & FT5000.

Has anyone on the list had the chance to do an A/B comparison between
the Orion II and the Yaesu FTdx5000? Particularly in terms of ssb
selectivity.
I used to have an Orion II and sold it (bad move!), but now much later,
have a Yaesu FTdx5000, but I am not satisfied with it's selectivity,
maybe due to only a 3 kHz roofing filter. So I am seriously thinking of
going back to the Orion with a 1.8 roofing filter.
Any comments?
Thanks and 73
