Public broadcasting[edit]

There should be a lot more on radio station broadcasting. The russians have many public radio stations between 150 and 270kHz because it can be heard several thousand kilometres away day and night (so that comrades are never left without bolshevik party propaganda).

Relationship to longwave article[edit]

This article's relationship to longwave needs attention — please see Talk:Longwave. (This impacts the point raised above.) — Johan the Ghost seance 10:27, 11 May 2006 (UTC)

Listed for deletion[edit]

I've listed this article for deletion so that it can be redirected to longwave instead. Gerry Lynch 17:59, 1 June 2006 (UTC)

I disagree: The "longwave" entry is specific to the longwave broadcasting service and does not cover all other uses of the LF band. It is better to add a "Radio broadcasting" subsection stub with "main article" redirection to "longwave". Sv1xv (talk) 11:07, 9 January 2008 (UTC)
This deletion request is no longer current, the discussion in 2006 is now closed - although there was 'no concensus' it will not be opened again. Dsergeant (talk) 12:17, 9 January 2008 (UTC)
You are right, but to resolve the situation for good I added the subsection and redirection, so the two articles can co-exist peacefully.Sv1xv (talk) 14:20, 9 January 2008 (UTC)

Unreferenced section[edit]

The following paragraph remains unreferenced since June 2007, so I moved it from the main article to the discussion. Can someone cite a source?

"In addition, Royal Navy nuclear submarines carrying ballistic missiles are allegedly under standing orders to monitor the BBC Radio 4 transmission on 198 kHz in waters near the UK. It is rumoured that they are to construe a sudden halt in transmission, particularly of the morning news programme Today, as an indicator that the UK is under attack, whereafter their sealed orders take effect."

Added back in, as there was a subsequent mention on BBC Radio 4 in late 2008. ~Excesses~ (talk) 19:15, 6 August 2011 (UTC)

Radio navigation signals[edit]

Could someone contribute something (especially references) about the DATATRAK radio navigation system? Sv1xv (talk) 11:16, 14 January 2008 (UTC) nm jmn m — Preceding unsigned comment added by 115.248.58.203 (talk) 12:57, 8 January 2013 (UTC)

contradiction?[edit]

"Propagation by reflection (the actual mechanism is one of refraction) from the ionosphere is also possible." vs. "Since these frequencies propagate by ground wave only, the precision of time signals is not affected by varying propagation paths between the transmitter, the ionosphere, and the receiver." 71.171.138.221 (talk) 01:12, 16 January 2011 (UTC)

Hello fellow Wikipedians,

I have just modified one external link on Low frequency. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
