Cheers for that Christoph, beats my post processing with timestamps fix!

For what its worth I've gotten away with fairly cheap TCXO's (£15 generic farnell ones) and a GPSDO circuit like the one at http://ve2zaz.net/GPS_Std/GPS_Std.htm (it did need some manual tuning at first as the oscillators werent within the frequency locking range from a cold start) - you do get what you pay for with (double) ovenized CXO's ones though. You tend to find them on the commericial boards (theres a mailing list post somewhere linking to a few options)


FYI - I believe the patch has been merged into the current git master - so you if you're tracking the git source you don't need to manually apply the patch anymore.
