[Boatanchors] Drake 4-Line Crystals

[David Stinson]

Most of you probably know this, but in case:
Those HC-6U crystals used for additional 
bands in the Drake 4-Line gear-
most of them will triple and some, even 5x
multiply to provide the mixer freq you need.
For instance:  If you need 12.6 MC to get 
your R4 on 160 meters, a 4.2 MC crystal
will triple there and work.   Active+ crystals
will do 5x. 
One caution:  Any freq error in the crystal
will be multiplied as well.
