    As most of us OFs are aware, low frequency, 100KC calibration crystals are getting to be like cold pressed latinum. I was just rummaging around in my parts drawer and re-discovered what I thought was one o' these gems, and noticed it was 120 Khz! Does anyone have any idea why anyone would need a 120 KHz calibration crystal? What was it even from? (It does have signs of having been plugged in to a socket at one time).

    Inquiring minds want to know.

    It's for people who can't read the fine print.

    Who says it's specifically a calibration crystal?

    I also have several of those "tall can" 120 kHz crystals.
    Always wondered what equipment they were used in.

    Hmmm....maybe the aliens left them behind. I guess I should build an oscillator out of this thing and see who calls home. Maybe you should do the same with yours!

    Then again, maybe we'd better not.

    They were used to let you know when you were 20 KHz outside of your band privileges :D
