How are changes in the earth's magnetic field used as evidence to support seafloor spreading?
There is a 'striping' effect where magnetic material on the seafloor is aligned in different directions. "...during the upheaval of the Flood the flow of the molten iron in convection cells in the outer core carrying the freely-decaying electric currents meant that the resultant geomagnetic field generated would have rapidly changed direction and reversed its polarity because of that fluid movement. On the sea floor at the earth's surface new basalt lava flows were erupting rapidly due to the rifting apart of the old pre-Flood ocean floor and mantle plumes in mantle convection cells rising as a result of the catastrophic plate tectonics during the Flood. Each new basalt lava flow recorded the polarity direction of the geomagnetic field at the time it cooled. So due to the geomagnetic field reversing rapidly, and the basalt lava flows being erupted rapidly, the result was that these geomagnetic field polarity reversals were recorded in these sea floor basalts, both laterally and vertically. This paleomagnetic "striping" within the sea floor basalts was one of the key pieces of evidence that convinced geologists that the sea floor plates had spread, pushing the continental plates with them, albeit at a drift pace within their uniformitarian paradigm. However, Humphreys was able to demonstrate that because the paleomagnetic recordings of the polarity reversals were often in patches within the basalt sea floor and even within individual basalt flows, the reversals having occurred rapidly within days was a better explanation. The catastrophic plate tectonics model for the geology of the Flood thus provided a better context to explain the geomagnetic field polarity reversals. Thus Humphreys had even predicted that evidence of rapid reversals would be found before Coe, Prévot and their colleagues announced their discoveries, which of course then provided confirmation of both the Humphreys geomagnetic field model and the catastrophic plate tectonics model of the Flood.

Is an insulated green grounding conductor required for amateur radio equipment?
You need a ground (which should be insulated because if you ever get energy on that wire it's going to be very high voltage) on any radio system with an outside antenna because of lightning - lightning likes to find the biggest conductor it can to go to, and your antenna is probably the biggest conductor on your block...especially if you like working the 40-meter, 80-meter and 160-meter bands. If your antenna gets struck by lightning, the ground will help direct the electricity to ground rather than to your headset.
What number is used to describe OK in CB jargon?

Does Africa have a spring and a fall?
Africa is a very large continent (about three and half larger than the USA) and is made up of 54 countries. In the northern parts and southern parts there are distinct seasons like spring and fall as we know them in the US. In other parts of Africa there are wet and dry seasons.
-- An over-modulated AM signal spreads to occupy excessive RF bandwidth. If it's
not the one you happen to be listening to but it's close, then its outlying products
can lop over into the adjacent channel where they don't belong, and show up as
destructive interference to the one you're trying to hear. If it is the one you're
listening to, then its outlying sidebands typically exceed the bandwidth of your
receiver, and the recovered audio to which you're listening includes excessive
audio distortion.
-- A carrier suppressed AM signal is only a problem if the receiver's beat-oscillator
lacks sufficient stability. The receiver is responsible for providing the carrier locally,
which needs to be very close to phase-locked to the missing carrier for decent
audio, and produces weird-sounding audio indeed if it's far from correct phase, or
wandering.
The best approach to receiving carrier-suppressed AM is to begin by sharp-filtering
the received signal so as to retain only one sideband, since the frequency- and
phase-stability requirements on the local oscillator are actually less stringent for
single-sideband detection. But there you go again with a more complex receiver.
How can you program a PRO-33 Realistic Scanner that has no instruction manual available?
I used The Google and learned there was a PRO-32 and a PRO-34 but no PRO-33. Either way, if you go to The Google and search for Radio Shack Scanner Manuals you can find the one for your radio.
What are uses of amateur radio?
Amateur radio is useful for:
1. Having fun talking to other hams around the world, or simply in your own town.
2. Keeping emotionally healthy. (Astronauts, most of whom are hams, talking to us hams on the ground.)
3. Passing emergency traffic across the land.
4. Providing communications between soldiers, sailors, and fliers from where they are stationed to back home.
5. Developing new equipment, concepts, methods, and modes of communications. Many of the radio technology today is founded in work done by hams.
6. Providing emergency communications service for disasters and other local disasters.
7. Providing for long-distance ham-to-ham communications by building, launching, and maintaining a number of Earth-orbiting satellites, like OSCAR (Orbiting Satellite Carrying Amateur Radio) and AMSAT.
When was Andy Devine into amateur radio?
Andy Devine, the American actor and radio personality, was involved in amateur radio during the 1930s. He was known for his interest in radio broadcasting and technology, which complemented his career in entertainment. His hobby reflected the growing popularity of amateur radio during that era, as many individuals sought to explore this new form of communication.
Where can you get a Atlas 350xl ham radio serviced in Orlando Florida?
In Orlando, Florida, you can get an Atlas 350XL ham radio serviced at specialized electronics repair shops or amateur radio service centers. It's advisable to check with local amateur radio clubs, as they often have resources or contacts for reliable repair services. Additionally, you can explore online forums or groups dedicated to ham radio enthusiasts for recommendations on technicians experienced with Atlas radios.
Is ham radio all narrow or wideband?
Legally, an amateur radio operator can radiate signal across as much spectrum as
he wants to, just as long as he keeps it all inside a frequency band allocated to the
amateur service. But the more spectrum he uses, the less there is available for other
users until he shuts down. So there's a great incentive within the hobby to achieve
communication with the narrowest possible radiated signal, and that's typically what
hams do. This practice also has the wonderful ancillary effect of making it possible
to communicate farther with less power.

HR Puffinstuff was a children's show. Starting in 1969, the show was based on the life sized puppet-like Puffin stuff, living on a magical island.
In ideal conditions the radiation resistance of a short antenna is proportional to the square of the height in wavelengths. So doubling the frequency would produce 4 times the radiation resistance.
Rr is 1578(He/lambda)2 for a short antenna, He < lambda/8.
He is the effective height, equal to half the physical height for a simple monopole, rising to the physical height for a monopole with an infinite amount of horizontal top loading.
Radio frequency energy causes a heating affect. You can get RF burns if you touch or get really close to a wire carrying RF energy. With powers below 100 watts and normal wire insulation, RF burns are extremely unlikely. Since RF currents flow in the surface of a conductor (your skin), an RF burn is not the same as a burn from a 100 Watt soldering iron (for example).
If you position your antenna feeders and antennas out of reach of prying hands, you will be safe.
Were Revell Short Wave radios any good are they valuable today?
The Revell KIT 1 was an inexpensive regen radio, circa 1962ish. I belive it was a 2 transistor multiband radio. I had one, and am looking for one now to complete my nostalgia collection. If you know of one for sale, any condition let me know.

Do you need a license to byr a ham radio transceivers?
(In the United States) you do not need a license to own a HAM radio. You may Listen to communications on a HAM radio without a license. However, you may NOT transmit on a HAM radio without a license.
How does the ionosphere help radio transmission?
Radio signals at a frequency below 30 mHZ can bounce off the ionosphere and be reflected back to earth. This is often referred to as DX skip. Sometimes, sunlight will excite the ions enough to where there'll form more dense spots within the ionosphere. These can, at times, allow higher frequency transmissions to use the same DX skip, although frequencies higher than 30 mHZ will normally pass right through it.
