Hi Bill
I’m not sure what I said for you to worry about me excommunication you!
There have been numerous articles about using solid state replacements for
VFOs in tube transmitters (DDS for one), and I recall that a recent issue
of ER had an article of someone using a solid state device to replace a
crystal that is now unobtainium --
I’ve never played with an Arduino; I spend a lot of my day as a software
engineer working with STM32 microprocessors for embedded systems. ST Has
numerous Discovery Boards available, and I’d probably go that route if I
had to simulate an end of life custom chip in a ham radio.
Fear not young fella….. thou shall not be excommunicated!
