XETRA is still booming into SoCal. It is the best AM signal by far around
here.
I listened to Bob "Wolfman Jack" Smith in 1963, on XERF, sponsored by
Stan's Records in Shreveport.

1520 kHz : KOKC-AM & KXA-AM

Heard 'KXA' ID on 1520 kHz @ 3:05 AM [PST]
Country Music {Rocky Mountain Music}

Nothing local on the frequency now. They must be on holiday.

KXA-AM [KKXA] 1520 kHz @ 50 KW
from Snohomish/Everett{Seattle}, WA -circa- 2011

....maybe... KKXA-AM Last of the 50KWs

Funny that they picked the second harmonic of the old KXA. To properly
resurrect the old KXA, they would be running dreary classical music.
And running a dipole on the roof of a local department store. (The
last medium wave wire antenna in the country, I think.)

Isn't the mega-talker in Sacramento that runs/(used to run?) HD-Radio
on 1530 or 1540? Having 50kw in their digital sideband would sure screw
that up.

Interesting on the 'last wire antenna' -- anywhere I get more info
on that, or pictures?

Here's another Last Wire Antenna: http://www.fccinfo.com/CMDProEngine.php?
sCurrentService=AM&tabSearchType=Appl&sAppIDNumber =92621&sHours=U

I've seen pictures (which I can't seem to find on the internet) of old
AM
broadcast antennas consisting of multiple parallel wires strung
between
two towers on the rooftop of a building. These were typically located
on
top of a hotel, with the broadcast studio in the hotel.

Were these wires truly parallel, or were they strung in a zig-zag
pattern
(which I'll try to illustrate below)? If parallel, what's the theory
and
advantage of having them parallel?

Dammit, I figured my illustration wouldn't display correctly. Does
anyone know why the text in my posts become fragmented? Is it
Google or Windows (or both) that can't even process simple text
correctly?

Your illustration appears to have come out fine here, showing a series of
parallel lines with "pipes" between each on the left hand side.

That's the one. They seem to have quit running HD at night.
Back when all that mess was starting, they were one of the only
two or three HD signals I could hear, here in Seattle.

I've seen pictures of antennas like that strung between the masts of
old steamships. Folded dipoles. The high-impedance feedline (ladder
line) fed the center of the center wire. Instead of a single additional
wire connecting the ends of the center wire, a bunch of parallel wires
were used, separated by several circular spreaders.

When you make an antenna with a large-diameter radiator, it is inherently
more broad-band than just a wire. The multiple parallel wires created the
equivalent of a radiator with the diameter of the circular spreaders.
In those days, antenna tuners were standard equipment anyway.
