I think accurate enough for now Alan. I plan to change the 27Mhz xtal for a
TCXO.

Now have an accurate 10Mhz source for very little money.
See http://www.m5fra.org.uk/low-cost-frequency-standard/
It does not look as if you have actually checked how accurate the Progrock
is?
I ask because I started to check a month or so ago but stopped for a break
when I found it was not being accurately locked and could not figure why.
It was better than 0.1Hz when clocked by a 10MHz GPS derived reference but
several Hz off when I used 27MHz and PPS.
