You have to remove the L feeding DC to the on board OCXO.   Then move a link or two to get your external input

The main problem I have with this module is that it does not have an input for external 25MHz source.  There is an SMA connctor marked MCLK but this turns out to be an output from the internal (crap) 25MHz reference which is a mile off 25MHz and not very clean..
Otherwise ist seems useable.
