You can hear the voice and see the fire and smoke caused by running high power on 40m. RF can fry you!

    Geez Chris, no tellin’ where you will turn up… it was good you explained
    in the comment section here that it was only for demo purposes because it
    didn’t look very “Boca”ish ! (k5cqe)

    if only people understood the wire and the pipe. Someone said its a coconut
    short of a receiver. If that wire was 6ft long it wouldnt work. Hes running
    on 7khz ANY wire thats long wire turn the wire into a ‘receiver’. The Meter
    of the band is the length of the wave. Much like putting the square peg in
    the square hole. MOST people have no idea how simple but cool radio can be.
    Not only is it above size-but specific size. AM receivers use wire length
    NOT Circuits per se to receive. Nice Video 🙂

    so don’t need electronics anymore to filter out voice modulation from the
    broadband. it meand that the wire is vibrating with his voice. and you be
    careful, if you touch it you might serverelly be skinburned temporally
    paralized or be killed dending on frequency and power of the broadband

    Don’t you know that you don’t use a full wave dipole on your Xmtr. a 40 Mtr
    band dipole should only be 20 meters long, with center feed. Your voltage
    node is at the end and being 40 mtrs long puts the voltage node at the very
    end. Thats why the arching, The antenna is way too inductive. And your SWR
    (with out tuner) is probably off the scale. And that is the worst setup I
    have ever seen for an antenna . I run 1200 watts P. E. P. and don’t have
    that problem unless the humidity is near 100% .

    Yes I’ve been burned by RF, hence my adoption of the name R.F. Burns. I was
    helping a buddy tune an R8 an I turned the wrong way and caught 50W on my
    left ear. Ouch!

    Another Caveat: Ham antennas can also RECEIVE very HIGH POWER in the form
    of lightning. I survived such an ordeal. You may not. Make sure you have
    lightning protection., and when Thor is in your neck of the woods, shut it
    down, ground everything, and wait it out until Thor has gone away. Install
    lightning protection WHEN you put up an antenna, and PLEASE don’t put this
    very important part of your antenna project off for “another day”…

    That was a typo on my half. You dont know enough about radio if what I said
    makes no sense. Just say I dont understand is all. Then id explain.

    This is done for demonstration purposes and it’s not how the antenna is set
    up. It’s just to show how you can actually hear the audio within the pipe.
