Radio transmitters, a thought.

Post by OpanaPointer »

Inspired by this thread: https://www.kbismarck.org/forum/viewtop ... 07ff07e5ae

The "war warning message" was sent to Hawaii via Western Union's 40 KW transmitter in California, the US Army's 20 KW couldn't punch through the solar flare "noise". Reading about a 100 KW transmitter lost enroute to the Far East made me wonder, what was the most powerful transmitter available anywhere at the time? Military or private?

Hi Opanapointer, there were a few as big or bigger than the lost Singapore 100Kw. In 1924 the BBC opened a new 150Kw Long Wave transmitter near Birmingham, England, and they also had a number of 100kw ones elsewhere in the UK before WW2. However, in 1933, Radio Luxemburg opened a 200Kw long wave transmitter in the Grand Duchy. See http://frequencyfinder.org.uk/History_Transmission.pdf

Of course, whenever we talk of biggest, America usually comes to the fore, and in 1934, in Cincinnati, a 500Kw transmitter opened, which ran for five years, see https://www.neh.gov/humanities/2015/may ... d-only-sup
One thing of interest here is the article describes the size of the thing, simply massive!

Do we know what they were using in Japan for military transmissions? I know Station Hypo and Station Cast were listening but did the Stateside facilities have a chance to catch any of that?

I've been past the Big Ass Antenna Thing (BAAT) at San Diego, back in the '80s.
