Thanks for more pics. Was there any indication of where the 10MHz gets its
signal? Could you see a trace, or did I miss that in the pics? I'm a bit
too ham-fisted to go prodding around in mine, so I've left it closed after
an initial urge to see the top of the board.

If you look carefully at the pictures showing the bottom of the connector
area on the 10 MHz and Antenna connectors you can see that the connectors
don't share any mounting/connecting holes on the PCB.

If you want 10 MHz out of the unit with the GPS module, you can get it from
the center pin of the unused connector. (You may have to add other parts to
get 10 MHz over there.)

An alternative migh be to move the antenna connector on the GPS module from
the bottom to the top, then use a pigtail lead to the panel. That may not
work. From the pictures, it looks like power to the antenna is added to the
trace on the bottom of the board.

Hal - there's nothing coming out of those connectors. I'll explore again once I can get my GPS connected to the unit and see if that changes anything.

when comparing bottom sides of ref0 and ref1 boards IC U207 near antenna
input of ref1 seems to be missing.
