What is the teddybaer?--Nollieheelflip
Can anyone explain how we can transmit in this range (e.g. 100 HZ would require a trasmitter of 3000km long (300,000km / 100) wouldn't it? How do we get around this issue?) Amilnerwhite (talk) 23:48, 10 November 2009 (UTC)
SLF is not an ITU symbol for this radiofrequency band
[edit]How do you prove a negative? The frequencies 30-300 Hz do not seem to have been given a name.
I found two documents the ITU published in 2015 that cover radiofrequency band names: one was a recommendation[1] and the other was the "acts" approved at a conference.[2] In neither one of these does SLF show up. If you dig through their Radio Regulations you can see that this is still the case. The bands with ITU-endorsed symbols are VLF, LF, MF, HF, VHF, SHF, EHF. 2603:7000:9501:3A00:25ED:362C:33E3:BD67 (talk) 03:15, 13 January 2025 (UTC)
