After all these years I should know this but the answer presently escapes me. In order to operate a Valiant I transmitter on AM using crystals instead of the VFO, what actual frequencies would the rocks for 75, 40, 20, 15 & 10 meters actually be cut for? 

Are they all fundamental frequencies or are some cut for the 2nd and 3rd harmonics? I'd like to have some on hand to transmit on, for example, 3885, 3880, 3875, 7290, 14286, etc. Any advice with specific examples would be appreciated. Thanks & 73, Bill, w0ng
