@Antinventor2020 The term "Radio" Frequencies are something of a misnomer, in that the original meaning of the term referred to Long Wave, Medium Wave and Shortwave Radio Transmissions...The term Radio Frequencies are being used for frequencies that now extend beyond the frequencies associated with Radio Transmissions, confusing I know ..
It seems to me you want to "tune into" the lower radio frequencies/wavelengths that Amateur Radio Operators use within the 1.8mhz to 30mhz range, approx 166meters to 10meters, for what ever purpose you have...Please correct me if iam wrong...
I have pdfs. im layman and ive had 0 electrical engineering experience. Looking forward to experimenting soon. For now, im still dabbling in a lot of theory.
I believe some of my pdfs have practical blue prints- Don Smith stuff, "A Practical Guide to Free Energy Devices" and the In Depth version should have some blueprints/how to's. Send me your discord if you're interested.
