[Boatanchors] Anyone making crystals now ??

Mon Mar 29 13:40:25 EDT 2021

On the Drake Groups IO list there is a design for a modern substitute for the
old Drake FS-4 synthesizer. This gives freq source to replace needing the
accessory crystals to give short wave or ham band coverage (where xtal is
lacking) on the Drake equipment. This is Arduino based and costs out at 15 to 25
dollars.

I found this other thing which uses the Elecraft XG test generator, which seems
an interesting alternative.
