Talk:Very low frequency

message: I added Renato Romero's "Radio Natura" book in the "Further reading" section. This is the first edition in Italian. It must be replaced with the 2nd edition in English when it is published, possibly in mid-2008. Sv1xv (talk) 22:13, 9 January 2008 (UTC)

message: Is there any way we could get sources for the table? Some of the information seems sketchy, such as the 22.3 kHz area. We don't even know where that is from, and many others have weird information as well. I found copies of this table all over the internet, but where was the original? 71.131.23.130 (talk) 05:39, 15 April 2008 (UTC)

message: Quite a bit of space is dedicated to the discussion of PC reception of VLF signals: wouldn't "PC based detection" be more accurate?, and shouldn't it at least be mentioned that many shortwave radios and communications receivers cover VLF as well?  —Preceding unsigned comment added by 217.157.224.13 (talk) 21:32, 23 December 2009 (UTC)

message: Why should this guy sit in russia? This source says that a 22.3 kHz transmitter is located in Exmouth and that is was used as a "add-on" for omega.

"In addition, the recent change of transmitting frequency from 22.3 kHz to 19.8 kHz has precipitated concern among station personnel regarding the safety of working on the towers."
So once they used this frequency, maybe they run the transmitter with it for 2 hours every month just to test if it is still operational.  — Preceding unsigned comment added by 77.3.138.184 (talk) 18:50, 25 June 2012 (UTC)

message: in: "Trideco" ... at a power of 1.8 megawatts, the most powerful radio station in the world.
It should be noted from UHF television broadcasting, "A UHF TV station could be licensed for up to five megawatts of carrier power"  — Preceding unsigned comment added by 192.225.121.101 (talk) 01:49, 12 August 2022 (UTC)
replies: text: Okay, but firstly we're discussing VLF Radio (radio carrying audio modulation) vs UHF Television (radio carrying audio and video modulation), so it's technically not a fair comparison. Either way, these would require research, because I think both, "facts" are dubious. Read-write-services (talk) 06:40, 19 August 2022 (UTC)

text: For the UHF TV they are talking about effective radiated power rather than total power. UHF can use directional antennas to concentrate the power to the horizon, boosting EIRP. Graeme Bartlett (talk) 08:42, 19 August 2022 (UTC)
