One reason for doing this is so that you do not have to use SPLIT, which
turns QRQ mode off. QRQ mode produces 'cleaner' QSK even at slower
speeds, and is pretty much necessary over about 35 wpm to avoid badly
malformed CW.
This is one of the 'rough edges' of the K3 which has to do with the time
it takes the synthesizers to reliably change frequency.
I use macros to take me into/out of "pileup mode', including activating
the subreceiver, putting the appropriate signals into the right and left
channels, moving up two kHz, etc. One minor problem is that the sub
balance control works backwards for my preferred placement of DX in the
left ear and pileup in the right.
I am not totally happy with this situation, but QRQ mode is important to me.

Forgive me, but I don't understand why anyone calling in a pileup would

The K3's Main RX and 2nd RX are identical in performance; but they are
not identical in ease of use. It always takes a few seconds more to
reach the functions of the 2nd RX because of the BSET button.
We need to ask ourselves: which station do we need hear the best; and
why?
The DX station that we are trying to work is the ONLY station that we
need to copy accurately and in detail. That station is also likely to be
quite weak, and these days we may also be fighting deliberate, malicious
QRM on the DX station's own frequency. For all of those reasons, surely
it makes sense to listen to the DX station on the Main RX (VFO A) where
all of the K3's QRM-fighting tools are instantly to hand?
The 2nd RX is completely adequate for tuning the pileup because we
aren't listening for details there. We only need to find where a station
is sending "599" and "TU", to help us judge where and when to place our
own call. We don't need to copy any further detail, so why waste the
Main RX on tuning the pileup?
For tuning the pileup with the 2nd RX, I have always found my saved
Normal passband settings to be completely adequate, and have never felt
the need to change them on the fly. There isn't time to do that anyway,
because in the next few seconds everything will have moved on.
Maybe this is all a habit, developed from using older transceivers with
a very inferior 2nd RX... but it still seems to make good sense today.

This is what I've learned to do. The only problem is that once you
enter
this mode, if you want to fool with selectivity, APF, shift, etc. to
hear the DX better, you must press BSET first.
