EMWIN Receive Test
    * About 80-percent efficiency rating.  (80-percent good packets and
    20-percent bad packets.)  Worked better than expected.  Was able to
    successfully demonstrate EMWIN for passers-by at the hamfest using
    RealEMWIN software on a laptop with video put out to an external monitor,
    and using a WX-41 demodulator hooked up to an HT and a temporarily
    mounted J-pole atop a 4-foot pole that was stuck into the ground at the
    front entrance of the building for a better signal.
