This looks like a lot of trouble for no real practical purpose, other than
maybe get a glimpse of a carrier an odd time on 8970 Kcs
The possibility of a real time QSO on this band over any distance looks
remote. In all it seems a lot of effort for little reward.
Mal, take a look at Stefan's signal at 904km: 
http://www.lipkowski.org/~sq5bpf/dk7fc_20101002/
the shorter lower frequency dash is abt 720s long, a 120s dash would still 
be detactable.
so DFCW120 is practical at 904km distance. DFCW 120 is considered a 
practical QSO mode by many.
btw Mal, maybe you should try your luck in transmitting with your big 
antennas. get a stable frequency generator, put up a carrier, and give us 
a chance. you might be surprised at the results.
