Shortwave FREQ help

[biferi]

I am new to Shortwave and I need some help with a fue things?

Shortwave is FRQ 1700 kHz to 30,000 kHz
But when you read about Shortwave it says it is H.F. Band but H.F is
3,000 kHz to 30,000 kHz

So witch is it does it start at 1700 kHz or 3,000 kHz?
And why do they say it is H.F. if it starts at 1700 kHz??

300 KHz to 3 MHz is "MF" (Medium Frequency). The generally-accepted limits of HF are 3-30 MHz. This would be 3000 - 30,000 KHz.

Ok 3,000 kHz to 30,000 kHz is HF but is shortwave 1700 kHz to 30,000 kHz?

If so Shortwave starts below 3,000 kHz so why do they say it is HF??

"Shortwave" is a relative term. "Short" compared to what?

Generally, it means shorter wavelength than domestic AM broadcast, or shorter than the wavelength of a signal at somewhere around 1700 KHz. I've never seen an internationally-accepted definition of where "shortwave" starts, as far as its lower-frequency end. Then, the wavelengths just get shorter as the frequency gets higher; there's no top end to "short" wave.

The terms "shortwave" and "HF" aren't directly related. A typical receiver might be able to pick up airport NDBs down in the 200-300 KHz range, and it might cover up to 32 MHz or so. Some receivers top out around 3300 MHz (3.3 GHz). Can it receive "shortwave" (however you define the term)? Of course it can -- as long as you don't plan to listen above the top end of the receiver's range.

Isn't "shortwave" typically used to refer to broadcast stations using HF frequencies?

Like BBC, VOA and others who transmit AM signals?

Much of the world uses the stations for news and music.

"SWL" seems to apply to "Short Wave Listening", that also applies to MW stations in the US.
