Dick - The band crystals you have listed are correct.

The oscillator crystal is 4.99 mc.  The sideband crystals are 4.005 mc and 13.985 mc.  There are
nine crystals in all.  Hope this helps.  73, Larry KC8JX

I would suggest you get a complete manual.  They are offered by many vendors who frequent this
list.
