help with ft100d frequency adjust

hello
 newly purchased from estate at super price
 rig hears well, power out on all bands to specs.
 rig seems to be off freq on 10m, 200 hz low or so and seems to continuing multiplying up til 440 band
 

 looked at schematic and removed covers- lo board seems buried deep under several other boards with kots of connections.
 any easy access to check freq of the reference oscillator?
 

 checked menus as well as service menu but no software adjustment that i can see, even to check reference oscillator.
 

 this may get sold as parts radio if no easy solution.
 tnx for any help anyone can provide
