[Repeater-Builder] Freq Cut for GE Exec II, need to know the formula

[n9lv]

Can anyone give me the formula to figure the cut for the vhf receive 
side of the GE Exec II radio.  I'm not 100% sure, but I think I have 
been sent the wrong xtals.  I'm looking for the cut for 144.810 if 
anyone can help.
