says: "Regarding the "Super Pro", it is operating in our
immediate 50,000 watt field. We
using three doublet antennas, 50' high and exposed to an R.F. field
from WOR transmitter
of 10 or more volts of R.F. We
to tune in all broadcasting stations between 500 and 1600 kc. with no
inter-channel interference. On
waves, we experience pre-selection enough to pick up all foreign and
with 5 and 10 kc separation from our harmonics. We
