Three reasons:

1. In Europe, almost every DXpedition station is being deliberately 
jammed, so the DX is much harder to hear than the pileup. In order to 
copy the DX station well, we need the main RX with all of its 
front-panel controls. The sub-RX is plenty good enough for prowling the 
pileup.

2. When the DX station does come back, the RX on the pileup is no longer 
needed. Like Iain N6ML, I often tap SUB to get the DX in both ears with 
the extra 3dB SNR. You can't do that when operating split the other way 
around.

3. Logging/control software assumes that we'll be operating split in the 
way the transceiver manufacturer intended. Anyone trying to fight that 
could easily wind up calling on the DX frequency.


By the way, we're still patiently waiting for the "quick split" option 
on the K3. To join a pileup with the K3 requires at least 4-5 carefully 
timed and sequenced operations. Competing rigs can get there with one 
touch.
