Very good Tony
Wikipedia sez

"Shortwave radio operates between the frequencies of 3,000 kHz and 30 MHz
(30,000 kHz) and came to be referred to as such in the early days of radio
because the wavelengths associated with this frequency range were shorter
than those commonly in use at that time. An alternate name is HF, or high
frequency.
en.wikipedia.org/wiki/Short_wave

As I recall the story At one time the bands below 200 meters were considered
worthless, so they gave the whole range to tha Amateurs
Soon they were sending signals across the atlantic

Why is it termed "SHORT" WAVE ?



"Short" is relative. The "wave length" is the peak to peak (or trough
to trough) distance between the waveforms as they'd be seen on an
ocilliscope. "Shortwaves" are shorter waves than medium waves, which are
shorter waves than Longwaves. At the inception of the science, "short"
waves were the shortest type used (commonly) at that time. Today, with
cellphones and things using wavelengths that go with gigahertz
frequencies, "short" waves begin to look really long by comparison.
