Do it!

(Another response): The Earth's ionosphere is a physical "object" layer of the earth's atmosphere, quite apart from skywaves, which are electromagnetic radiation trajectories. Certainly the state of the ionosphere is critical to the propagation of skywaves, just as the opaqueness of glass is critical to the transmission of light. But skywave is an important and separate phenomenon which has played and still play a critical role in radio transmission. While the current "skywave" article is minimalist, a complete study of the phenomenon from many angles (scientific, technical, historical and political for starters) could easily consume a very large volume. It's a complex and fascinating technical subject. For these reasons I suggest that it be kept separate.

I have to agree with this logic and say not to merge the two pages. KeoniPhoenix 12:29, 21 August 2005 (UTC)


[edit] Correction

The wavelength of a signal in meters is 300,000/frequency in KHz. Thus the wavelength of a 30KHz signal is 10,000 m or 10 Km. The ionosphere is at about 100 Km, so I corrected what an earlier editor wrote changing 30Khz to 3Khz. Although I'm not certain what bearing a wavelength greater than the distance to the i-sphere has on skywave prop. Twang 20:56, 20 February 2006 (UTC)

NB. You mean kHz and km. KHz and Km are both incorrect. There is no SI prefix "K". K is for Kelvins.--Srleffler 22:29, 20 February 2006 (UTC)
Oh my god, a typo on the Talk page. (Tell the people who use MB for megabytes)Twang 22:54, 23 February 2006 (UTC)

[edit] Note on Sporadic-E (E-skip)

possible correlation with lightning, which is associated with whistlers sprites et. al., which may be the result of draining iono. charge to earth's surface ... which may "light up" the iono-surface somewhat. Might be a thought should someone decide to go all tech on the subject later.) -- Twang 09:17, 22 February 2006 (UTC)

[edit] Cleanup

This article needs to be broken into sections, and the See also and External links lists are really long - can they be incorporated into the text somehow?--Kharker 18:44, 14 June 2006 (UTC)

  • Kharker: I've done some of what you suggested. In the event that the article doesn't attract other editors, I could try to incorporate more links into the article. Some of them are peripherally related, but I think their presence is hypertextual for people trying to traverse the subject of radio; short of consolidating all articles on propagation (which would certainly overload article length and discourage more depth later on) I think it's a good mix.
