Thanks for explaining that to me, a licensed amateur radio operator for more than 20 years. :p I meant the AM radio broadcast band as an example of a popular use case of radio in the early days when the "high frequency" designation was made. They are extremely low frequency compared to where most radio communication occurs today, orders of magnitude higher. Not literally ELF, which isn't used apart from extreme niches.

My reply was less in explaining it to you though, but more as being informative to others who might’ve not had the experience and thus could learn misleading information from your post. (I’m also a licensed operator, but not for as long as you)
