[Elecraft] Filters for K3

[N2TK, Tony]

Why not use HI Cut for SSB and WIDTH for CW. This way I find I usually do
not need to do anything with SHIFT for SSB.

The way IF SHIFT controls have worked on radios for decades now has been
that, as you turn in one direction away from the center knob position, you
are both narrowing the bandwidth *and* shifting the apparent center
frequency (what the K3 calls "FC"). Since the K3 has separate controls for
WIDTH and SHIFT this is not easily done without having to adjust two
controls.

A workaround (to return to the old way of thinking about IF SHIFT) is to set
up macros that give you the desired WIDTH and FC with one button push. In
this way you can emulate, for example, what the K2 does with its four
pre-set filter settings per mode.
