Thanks for mentioning the actual frequency. The article says "long wave" many times without specifying what it actually means.

"Longwave", usually written without a space, is an informal and not well-defined term for radio frequencies lower than the AM broadcast band, which in Europe is known as "medium wave".
In the USA there have never been commercial longwave stations, though various WWV time signals are broadcast in that band.
