[Yaesu] crystals for ftdx-560

[yash at aol.com]

 There are twoopen crystal positions on the ftdx-560. since the rig works in 500kcsegments I would gather that the rig could be crystalled to cover the17 and 12 meter bands,like the drake  B-line,  Right or wrong?, Ifright ,does anyone know the crystal frequency that would be needed, toorder the right crystals?   Same as  a ft-101? can't find the info anywhere. 
Thanks for any help on this.
