You can if you do not tell Pluto about the clock
change. Did you change the "Xo-correction" line to show 25000000?

ps why mess around with 25 megs?? the signal quality
is lower when not using 40mhz!!
In my portable QO-100 station 25 MHz reference signal used for
two blocks: 1) for LNB PLL with modification 2) for Pluto.
It's much easy to have one reference frequency for all modules
then two frequency values.
This 25 MHz reference source has low Allan deviation and low
phase noise - this solution has been checked with many
traditional QO-100 ground station sets in digital modes.
I am not sure that you can fill the difference between 25 and 40
MHz reference frequency for Pluto on QO-100.
