Well done Ziggy, I for one am grateful for your efforts, I commented previously
on the high standard of construction but I couldn't believe that the angles of
the screw slots at the corners of your schematic are identical to those in the
lid of my TS65! grin

Hi
If you *need* to lock one of the new FE-5680's 10 or 20 Hz high, you
probably can adjust the cap on the VCXO center it's range up there. I doubt
it will reliably adjust out to 300 Hz though. For that parts changes or
board surgery probably are required.

The frequency division is done by digital logic inside a CPLD and

Hi
The PPS would indeed be off if you move the 10 MHz (no matter how you do
it). The range of the output relative to the 380 Hz digital tune range is
restricted by the pull range of the VCXO. There have been plots posted
showing the pull range, and it's (lack of) centering.
No need to re-shoot

You might try compressing the file with something like 7z, or zip.
That should reduce it about 10x in size.
