RE: isnt a crystal a crystal?
If the crystal is accessible from the outside of the case, I can find no FCC or AMA regulation that prevents the user from changing crystals.
And every time this subject comes up, I ask for someone to cite an applicable regulation. So far, none has been presented.
I know this is fanning the flames, but I'm tired of people who continue to say this is against FCC regulations.
Show me the law and I will gladly comply.
