    All, Looks like my switch is not working correctly..

    with 12 volts applied..

    ANT- XCVR= Open
    ANT- SDR RX= Short
    XCVR-SDR RX= open

    ON TX All seems OK

    ANT- XCVR= Short
    ANT- SDR RX= OPEN
    XCVR-SDR RX= open

    Saw something about J3?? I have NO Jumper installed..

    I would think that in RX Mode both SDR Rx and XCVR should be connected to the ANT..

    Maybe I am wrong BUT Please Advise..

    Thanks
