[DX] last 2 and CW

[John Geiger]

After listening to some recent SSB pileups, including
in the CQWW contest, I have learned that the way to
call DX is using the last two.  I understand that this
comes from DX nets, which I have participated in
before (start the insults), and that the last 2
letters carry a unique propogation advantage over the
full callsign.  Somehow the F2 layer has a lower MUF
for 2 letters than for 4 or 5 letters, and less
absorption takes place in the D layer also.  The way
to work DX is to shout phonetically the last 2 letters
of your call until everyone else is sick of hearing
it, and then work the DX.  

Well, given the success of last 2 callers, why hasn't
this format been adopted for CW and RTTY pileups.  I
never hear it occuring on those modes.  It seems that
us CW and RTTY DXers are missing out of lots of DX by
signing with full callsigns.  So, is the propogation
advantage of the last 2 letters mode specific, or are
us CW operators fairly dense to miss out on THE way to
successfully break DX pileups?
