Supporting Terry on this one.  Richard Hull tried to detect fundamental
of Nemesis, max pickup distance was < 2 city blocks.  Also had fellow
experimenter Bill Richards who is a lowfer HAM try to detect 54kHz
fundamental on opposite side of Richmond (~ 20 mi as crow flies)..

ZIP, ZERO, NADA.  Nothing was detected above white noise level.
