In recent years many Canadian fulltime AM stations have been shut down
on AM and moved over to FM. However they remain notified which is
a semitechnical term meaning the Canadian government tells other
countries such as the US, which are signatory to treaties, that those
facilties still exist. The
What some broadcaster won't do to get a signal their market. There is
an AM station out on pilings in Biscayne Bay or at least there once
was. I don't know how it could have survive Hurricane Andrew if it did.
But the station and four tower array was put there to avoid interference

In the 60's I used to do a jazz show on on a 1570 Khz radio daytimer
station in Golden Valley, MN which is now KYCR. I remember a station
which claimed to be in Del Rio, Texas but actually had a super high
power AM station located across the border in Mexico.. I think the call
sign was XERF
WLW shared the frequency with other stations, I believe one in Canada. I'm
pretty sure that is why they had to use a directional pattern at night.
Throughout a long history, WLW shared (and time shared) channels.
The tower is a diamond shaped half wave, which makes it electrically shorter

Hello Herb and all,
In the early 70 I was on one of my many trips to DL land. My friend DL2VP, now
SK, was an engineer at DW-TV and German Radio
on 1584kHz. The final was 12kV at 80 Amps. 960kW input. The vacuum variables
were bigger than trash cans.
The power-supply took up a room about 12 X

I haven't heard the farmer story, but in the 60's lived 1000yds from the
KDKA radio tower in Allison Park, PA. That area is rough up and down
small hills, not much farming. KDKA/Westinghouse did experiment with
400kw short wave at the old Saxonburg site. We didn't have any RF
problems, but
My uncle W2NPR George Saviers(SK) was an RF engineer at KDKA radio in
the 1930's when the original Saxonburg, PA 718' tower collapsed due to
a guy failure while under construction in 1936. As he told the story
the guy cable ends were flayed out and potted with molten zinc into a
