  • I am helping out
    with the estate of a good friend of mine who was a ham radio operator and
    collected vintage gear for many years.  I
    will be listing his equipment during the coming weeks and months.
    Cooler weather and longer nights are coming which makes for a great time
    to build an electronics kit.  Here is an unbuilt
    version of the original WBR 40 meter receiver. 
    This simple and neat project comes from an excellent article of Dan
    Wissell, N1BYT, published in QST, August 2001, p.34-37.
    In a nut shell, the design of this receiver takes the advantages of a
    regenerative receiver (simplicity, sensitivity) and tries to address the issues
    which are antenna radiation, microphonics and hand capacity effects. The design
    uses a sort of Wheatstone Bridge design for coupling the antenna to the tank
    circuit.  For more information, you can
    Google “WBR receiver.”  There is also at
    least one YouTube video on the WBR receiver.
    I’ve taken a number of photos so you can see exactly what you are
    getting.  This kit includes the circuit
    board and all electronic components, plus a copy of the original QST article.  You will need to supply the knobs and a
    cabinet or project box, plus hardware. 
    An earphone is not included.
    Please see my other auctions for other radio kits plus a neat little kitsrus
    Kit 27 audio amplifier kit that can be used with some of the kits to provide
    more audio and drive a small speaker.
    Sold “as is” but guaranteed to be as described.  Please check my feedback.  Feel free to e-mail me with questions.
    I strive to provide an
    accurate description and complete disclosure of the items I list. If the item
    does not meet your expectations please contact me prior to leaving feedback so
    that I may address any issues. I make every effort to ship within 2 business
    days of receiving payment.
    I will use USPS
    First Class Package or USPS Priority
    Mail for shipping, whichever the buyer prefers. 
    International bidders are also welcome where eBay’s global shipping
    program is available.  I do not charge
    for packing and my packing is second to none. 
      Thank you for looking.
