[Elecraft] Diversity Mode - DATA-A

I've been playing around with diversity mode on 40m - having just put up a
vertical off to the side of a horizontal dipole.
I have to say, listening to 40m is a delight with diversity turned on - CW
and Phone signals just float around in space when you're wearing the
headphones - very 3D. I haven't been playing with it long enough to tell
whether its going to assist copy or not - but certainly an interesting
effect and preferable to how it was before.
Anyway, the real reason for the vertical was to get a bit more RX traction
on 7.076 JT65a - looks like I need to put out more radials because the
dipole is still winning by a few db.
So, I'm presuming that in DATA-A mode, each antenna is effectively being
heard on respective L & R channels on the line-out jack? It looks that way,
just want to confirm that it's the same as what's coming through the
headphones.
I've also set up a macro in HRD to send !BEFF to the rig which, according to
previous posts, combines the audio in diversity mode. Having done that, I
had this sneaking feeling that I was copying (decoding) better - but it
could be wishful thinking and needs proper testing, not just playing around.
When I say decoding better - it's not just a matter of dBs, it's a matter of
the reception holding together for a full 48 seconds in each minute through
QRM & QRN.
Anyone else out there tried diversity in DATA-A?

PS: Any news on when VOX is going to be implemented on a per-mode basis, ie.
DATA-A vs Phone?
