question based on a dim memory and some updates

International Crystal made several different little modules.  Crystal oscillators, mixers, amplifiers.I'd need to look through some old QST archives to find their offerings.JoeSent from my T-Mobile 4G LTE Device

Product names, vendors, data along that line.Schematics of the various modules?Given all the neat modules on places like Amazon, was wondering if this could be a product again.One of my x bosses made a converter module that took an ordinary vehicle AM/FM and turned it into a multi mode AM stereo receiver with pilot detection.Been working on some projects.This is my second batch of Type 538 camera batteries as a work in progress.https://imgur.com/gallery/dVlXKHKBeen playing with an idea of making a power bank for a laptop I have here. It would use hot swapable power tool batteries.So far the prototype has been kinda neat.Share a thought as time permits.Thanks in advance.MikeMichael F.
