    Flat shipping on multiple items in this listing.  If you wish to purchase more than one item, please use the add-to-cart option before checking out.
    Your choice of 40m Ham phone-band crystals.
    These are all real pressure-mounted crystals
    , no old cases stuffed with modern crystals.   If you are looking for other frequencies please see my other listings, or visit my ebay store where you can browse crystals by frequency range.
    All of these are tested and guaranteed.
    You can choose an available crystal frequency from the list.  The photographs are of the actual crystals for sale.  Zoom in on the photographs to get a closer look at an individual unit.
    You are purchasing a working crystal.  All have been checked in a test oscillator checked for reliable keying an actual Johnson Adventurer under load.  Most if not all of these I've used on the air at one time or another.  Actual oscillation frequencies are near what is marked, consistent with the aging and tolerances typical of this stuff.  Expect a little variation depending on circuit constants.
    Many of these also multiply up to good frequencies on 20, 15, and 10 meters.  You can do the math :-)
    Go have some fun!
