The 10MHz output comes from the XC9572 CPLD but the fact that it's there for a few seconds makes me thing it's possible to recover it, by fair means or foul.
It's possible it's just a gate, certainly looks like it's bing switched off and there's a file which claims to be a dump of the CPLD (as well as a few other binaries) so it may be possible to trace it back but I'd want to try and dump the CPLD contents from my FE so I'm going to build a JTAG cable. The other option which may be more practical would be to add my own DDS (already designed and built for another application but would need to be modified a little and repackaged) and use the 30MHz CPLD output that's always present when the unit is locked to get programmable spot frequencies.
