     AM might get a rebirth if those idiots who design receivers would use
more than a single chip AM tuner, loopstick antennae, and those DAMN CERAMIC
FILTERS with a 3-4 kc bandpass(!).  I've heard the Sony (we've a 50kw stereo
AM station, WBT, and a 5kw, WSOC-AM) and it can't touch a McKay-Dymek AM-5
for overall fidelity, regardless of the number of channels.

     The average Toyota or Ford AM-only radio can run circles around the stuff
being put in the FINEST home components these days. Jensen made a halfway
decent AM tuner for the car (with an outstanding FM tuner), which prompted
Mike Dorrough (yes, the inventor of that godawful Discriminate Audio Processor)
to praise it up and down while riding in my car back from the transmitter
site of WENZ Richmond (now WNWZ--all news.)

      WENZ's transmitter (Collins 20V3-what a classic!) could hit 30 to 15000
      with EASE.  This was in 1965.  We had specially eq'd phone lines
from studio to transmitter. The only problem was, while radiating this fine
signal, no one could hear it because their damn receivers chopped off all
the high end.

      This isn't a treatise on the design of receivers, but I wonder how many
people who pooh-pooh AM as a transmission medium realise that fully 50% of
a left-only or right-only FM signal comes from a suppressed carrier AM signal?
