[ICOM] Icom Dual Watch

[John Germanos]

Lots of discussion about this topic.
I might be wrong, but how would Dual Watch be very effective when using
narrow roofing filters.
The 756PRO has a fixed 15KHz roofing filter, so I can see that Dual Watch
would allow me to listen "up five to ten", while chasing after a SSB DX
station, for instance.
However, if I have a newer radio 7700 or even the 7600) with a 3KHz roofing
filter selected, I don't see how I would be able to listen "up five to ten",
with the Dual Watch system, very effectively.
Roofing filters are designed to attenuate signals slightly above and below
the wanted listening frequency.

Narrow roofing filters (with all their benefits) or Dual Watch. Don't see
how you can "have your cake and eat it".
Narrow roofing filters are great for contests. Dual Watch is great for
chasing DX.

What am I missing here?
