The pics of WSUN towers are very beautiful and makes me want a water tower.
And all this talk of radio boats remind me of Radio Caroline, the famous radio ship named for Caroline Kennedy, daughter of President John F. Kennedy.
TheLegacy could launch Radio Ivanka.
Oh I Don’t Know
AMRadioLegend means well: “breast implants traded for promotion etc.”
I’ve never really considered breast implants. I mean, what would it do? Would more people listen to my program if I had something in the way of breasts?

There’s a third category of station yet to be invented. But let’s start by talking about the two existing categories.
A commercial radio station is paid to air advertisements for products and services, or to schedule specialty programs by outside producers.
Commonly known as public or…[Read more]
Many wireless microphone models are part 15 devices, and along with the general category of wireless mics have been undergoing a still unsettled shuffling as frequencies are being re-assigned during the ongoing large-scale repack in which almost every broadcaster has to move elsewhere involving frequencies and towers.
Imagine trying to do all…[Read more]
From its opening which begins by describing one method of physically raising the surface of earth by the addition of dirt, it was our intention to advance through additional methods of raising the earth-ground in such a way as it would provide total or incremental suppression of radiation from a wire ground-lead encased within a…[Read more]
Welcome Mark to the Above Ground Discussion
Said: “This is not like getting a different opinion from different doctors…..this is a whole lot simpler. It’s black and white.”
Low power rules are certainly a whole lot simpler than medical science, but our rules are only sketches, which is to say, they are ball-park readings and measurements wit…[Read more]
Shiftiness & Other Non Sequiturs
Off course response: “Everyone is able to promote and install whatever unlicensed transmit system they wish to.”
Not a true statement nor does it apply to our purely academic discussion.
Go over to ALPB where you’ll be out of reach.
Teacher’s excuse: “…the topic of elevated Part 15 AM antennas was first introduced in this thread by Rich Powers End80, with a post from which the clip below was taken…”
R.Powers & I have talked strictly and only about elevated ground-leads at a serviceable level to establish security and reachability by the operator, 9-feet at t…[Read more]
Over to Rich: “…installed on the top of a tall mast, and using a long, radiating conductor connecting the transmitter ground connector to a buried ground rod.”
Why the hell are you bending this discussion into the illegal realm when it’s only been about legal installs? That’s what caught me earlier because I wasn’t looking for a…[Read more]
Going Over Everything
In the opening post of this thread I made the statement: “It has been claimed that wires above the earth-surface always radiate, whereas those below that surface do not.”
That is an untrue statement, although no one called me on it.
For one thing above-ground radials work the same as buried radials, even Rich allowed as…[Read more]
I understand why you’d wonder: “However wonder how that would factor in to the 3 meters.”
By considering the truck body a ground-plane it would represent true ground and not be part of the 3-meter measurement.
But because the truck body is not buried in the earth and not of a symmetrical configuration, the question rises…[Read more]
Just earlier, in Post pm #110451, Rich demonstrates with NEC4.2 that a legally compliant part 15 installation under 15.219 can and has been subjected to an NOUO from the FCC.
What are we being told?
For one thing Rich shows that 2-miles can be reached after all, overshadowing earlier estimates that 1-mile is the best expected. That…[Read more]
End80 Advises: “Keep the range limited, that should be a part 15 broadcasters primary concern.”
Absolutely, and I guess that the concern by the FCC about range is a balance between leniency for the low power operator and the interest of licensed broadcasters who reasonably do not want unlicensed services to compete with them.
I would…[Read more]
End80 recalls a moment in part 15 history: “Does this story ring a bell for any of the long term members here?”
R. Powers, my memory matches yours exactly… the red truck, the portable ground-plane, one or more regular parks or parking-lots for I think weekly or maybe holiday broadcasts. And I think he put up a sign.
It was…[Read more]
It has been generally established that wires and metal rods running at or below the surface of the earth are not included in the standard 15.219 3-meter measurement of antenna, ground-lead and transmission-line. This is because such wires/rods are not expected to radiate.
It has been claimed that wires above the earth-surface always radiate,…[Read more]
