    Description

    YOU ARE  PURCHASING ONE LOT OF TWO HAM RADIO CRYSTALS IN THE FT-243 STYLE HOLDERS, 3985 AND 7285 KHZ. I HAVE INSTALLED THE HC49/U TALL VERSIONS OF THE HC49 TYPE CRYSTALS IN THE HOLDER CAVITY. THESE ARE USEFUL FOR POPULAR AM FREQUENCIES.
    I SOMETIMES FIND THAT THE SMALLER HC49/S CRYSTALS WILL WIMP OUT IN VACUUM TUBE CIRCUITS, BUT THE LARGER HC49/U WORKS GREAT IN MY ONE TUBE TV SWEEP TUBE (50CD6) CW TRANSMITTER. IN MY TRANSMITTER, WHICH RUNS ABOUT 100 MA PLATE CURRENT, THEY WORK JUST AS GOOD AS THE FT-243 WITH A STANDARD CRYSTAL ELEMENT.
    I HAVE SEVERAL OF THESE, SO THE PHOTOS ARE GENERIC. THE CRYSTALS YOU RECEIVE WILL BE IN THE FT-243 HOLDERS, SIMILAR TO THOSE IN THE PHOTO. ALL CRYSTALS ARE TESTED BEFORE SHIPPING AND GUARANTEED TO BE GOOD OSCILLATORS.
    SHIPPING TO THE UNITED STATES ONLY.
