Talk:High frequency

message: "High frequency" is also used as a superordinate concept of "radio frequency" and "microwave". This is missing in the article. Have a look at "further readings" and "external links"! Several times, when high frequency is mentioned, not the 3-30MHz range is meant.  —Preceding unsigned comment added by Ax0p (talk • contribs) 12:15, 1 August 2008 (UTC)
thread_title:  Missing meaning of the term "High frequency" 

message: I think there should be a click on to the concept of FOT (frequency Optimum de Travail) between the MUF and LUF click ons, i.e. the optimal frequency for a communications path at HF.

If I knew how to do it I would do it myself,but I am a newbie at this and afraid I'd screw it up.

:Done - if that was the kind of thing you had in mind. --Nigelj (talk) 15:32, 22 February 2009 (UTC)
replies: text: Yeah, I was trying to reflect what was said in the cited sources.  I also think the context was 'worldwide communication' via HF, not just the easy single-skip stuff.  If we can find a good, reliable QRP source, specific to HF, then lets quote it. --Nigelj (talk) 21:10, 15 July 2009 (UTC)
thread_title:  FOT 

message: We mention that CB radio at 27MHz is considered part of this band.  Those same frequencies (27MHz up to at least 56MHz) are used for radio controlled models and toys - at least in some parts of Europe and N.America.  Surprised to see no mention of it here.
