The 2,800 acre Edward R. Murrow Transmission Site via Google Earth.

What is the world’s largest shortwave radio transmission site?  This is the question recently posed to me by filmmaker Amanda Dawn Christie, who is currently working on a documentary featuring Canada’s decommissioned RCI Sackville transmission site.

While I know exactly what North America’s largest government transmission site is–the Edward R. Murrow Transmission Site–as well as North America’s largest private transmission site–WRMI–I’m uncertain which is the largest site internationally…Is it one of these, or another?

Specifically, I believe Amanda is interested in the largest transmission site in terms of transmitters, antennas, and utilized land area.

Can anyone shed some light on this interesting inquiry? Many thanks in advance!

And if we do determine the answer, it will, of course, be posted here.
