[BC] AM Radio Kit

[Mark Humphrey]

I have received a carrier here at a distance of about 18 miles from Part 15
"1620 WNAR", but modulation wasn't intelligble.  It was possible to sense
some audio down in the noise -- but the only way I was able to confirm it
was WNAR was to bring up their internet stream and match the pattern of
syllables, accounting for codec delay.

I'm using a large outdoor antenna and on a good day can get just enough
signal to count WNAR's carrier frequency on my HP 3586C selective level
meter, with bandwidth set to 20 Hz.  Of course, at night the skywave signals
cause major interference.

I think WNAR uses a Rangemaster atop a pole.  The website claims they have
multiple transmitters, but when I've driven around Lansdale, it sounded like
a single site.  See
