>>>515507 still has 2 paragraphs of utter bullshit at the end, needs to be removed

>>517139

it's all true. up to you.

>>517147

only the last 2 paragraphs of 515507 are false 515502 is true

>>517181

it's an awfully large project, to disprove something like this (especially when you understand the topic) some form of RF mixer is required to achieve the effects described in the second to last paragraph, there are many, air is not one.

physics says not the way it's described, yes you can transmit an ELF signal inside a VHF carrier. I'm saying it doesn't magically come back out.

>the author seemed to be implying the sum and difference signals were transmitted separately and as such would need two very different antennas to operate efficiently.

i got the opposite of that but all the rest

yes

IMHO the intent of the post (or wherever it originally came from) was classic propaganda 90% truth.

Sorry, for my vocabulary, i rarely discuss RF engineering, i just do it.
