Wondering if some on the forum has made a 3 position or more crystal switch.
Looking to do this with transistors.
I tried a circuit and did not work Ill post the picture of what I tried.
I don't need an oscillator just something to switch in 3 crystals 4 xtals the most.
I tried the below and would not switch from 1 xtal to the x 2. I know this shows the x1 and x2 to oscillator but tried to read the circuit with my crystal/oscillator reader and would read x1 when powered and when x2 powered still reads x1 like its not switching.
looks like this is using diode biasing and I think a transistor circuit might work better.
Any one out there have any circuits/schematics.
The circuit im working with is using crystal switching. Its not an oscillator circuit for signal injection.
thanks
