##### Distance from the Earth to the Moon ? Ham Radio vs. Flat Earth Measurements.
« on: April 06, 2013, 11:17:37 AM »
I got disgusted with the way this subject was going and originally deleted my OP but am re-inserting if just for the record.

A radio signal aimed at the moon and transmitted from the earth to the moon on  an Amateur Radio "Moon Bounce" operation  travels to the moon and "bounces" off the moon and is returned and travels back to the earth and is received back at the earth 2.55 seconds later for the "round trip" time.

2.55 seconds divided by 2 equals 1.275 seconds for the "one way return" from the moon.

The speed of radio waves has been proven to be 186,000 miles per second. The earth's atmosphere has been proven to be of a neglible effect. The rest of the distance is "outer space" or a vacuum which has no effect.

1.275 seconds  times 186,000 miles per second equals 237,150 miles

I rest my case. So do hundreds of amateur radio operators. Period.

The result is not as precise as those done by other methods, but is close enough to prove the point.

How does this  method compare with the FE Measurement of 15 KM ?

2.55 seconds / 2 x 186,000 miles/second= 238,000 miles (approximately)
No it doesn't.

It gives 4.259×10^-9 s^2/m  (seconds2/meter), which is a nonsense.

Check your math. You need to do the operations in order, it's not 2.55/(2*186,000), it's

2.55 / 2 * 186,000 = 237,150

The calculation is rather simple; it's already been done. Given a time of 2.55 seconds and a speed of light of 299,792km...

2.55seconds x 299792 km/s / 2 = 382,200km or ~~ 0.993 × mean Moon-Earth distance.

The 'moonbounce' or EME communication produces a measurement very close to the accepted value for the average Earth-Moon distance of 384,400km.

Now the discussion can go beyond Th*rk's trolling attempts. Th*rk is terrible, people. Ignore him.

ITT: RErs confuse ham radio with RADAR and assume some guy in his shed can bounce signals off the moon. In actual fact you need a dish the size of football field and a small power station to yourself, but its something you can do at home and there isn't a sniff of conspiracy about this tall tale.

Question, if you can bounce radio off the moon, why do you lose reception in a valley?

They both work by transmitting an receiving radio signals, so I don't see a problem there. Ham is nowhere near as accurate for locating a target in 2 or 3 dimensions of course, but is still perfectly capable of measuring range.

In actual fact you need a dish the size of football field and a small power station to yourself...

Did you work that out yourself? I'd like to see the calculations on the size of the dish and the amount of power required for a moon bounce. Anyone (other than Thork, who has demonstrated appalling mathematical ability) want to provide those numbers?

Question, if you can bounce radio off the moon, why do you lose reception in a valley?

Because the radio you are referring to losing reception in a valley is attempting to communicate via line of sight with the other transceiver, and does not have the capability to bounce it's signal off the moon. Someone who knows more about ham radio operation can elaborate on that.

Ham radio is just a synonym for amateur radio. It's not a term that describes the equipment used. This being said, the idea that the equipment needed to perform a moonbounce experiment is somehow outside the realm of possibility for an amateur radio enthusiast is a misconception. The idea that you'd need a dish the size of football field and a small power station to yourself is a blatant lie. Unless you're talking of a tiny football field (lol) and your idea of a small "power station" is something the size of a portable generator.

There's a list of EME radio enthusiasts/stations here. Many of them have websites and/or e-mail addresses. Most of them seem to use radio transmitters of no more than 2000W; in fact some claim to use radio transmitters of less than 1000W. Quite a few of them use relatively small antennas or dishes; less than 10m. Some even on the scale of 4-5m.

If someone wants to prove that amateur EME communication is a lie and put one more nail in the coffin of the "round Earth", they might try contacting some of these enthusiasts. They might also try to find an expert in radio communication, someone trustworthy, and go have a look. Talk to those people, see if they have a "legitimate" equipment setup or not. Hell, try to convince them to perform a moon-bounce for you. Who knows, maybe some of these amateurs would welcome a visit. It's worth a shot.

Yeah, I know... silly me. I'm suggesting that the people in charge of the Flat Earth society, or its more prominent members, might actually go out and do some honest-to-god investigating.

Just contact someone at your local Federal Communications Commission Office (FCC) or the American Radio Relay League in Newington, Connecticut if you won't take my word for it.
I find it hard to dispute a commonly known fact.

Or any "Ham" or Professional Engineer in the field of  Radio for that matter.
Some hams have even done this with powers in the milliwatts.

And please do not confuse Amateur Radio with "CB" or Citizen's Band Radio. Amateur Radio Operators are licensed by the FCC and must take and pass an examination concerning regulations and theory in order to be granted a license.

Any one can purchase a CB Transceiver and operate on a special band without a license (11 meters for example.) There are good "CB'ers" but "CB" is a dirty word to a lot of hams. Some truckers have given CB sort of a bad image.

Let's make it simple. Divide the round trip time in half and multiply by the speed of radio waves and you will still come up with about 238,00 miles or 382,200 kilometers. Check your math again.

Silly me, too. I'm no math whiz. But there does seem to be a rather big difference between 3000
miles and 238,000 miles. I probably used the wrong symbols for division and multiplication in my example listed.

I'd be amazed if they'd actually contact anyone on this. The main page of the Flat Earth wiki reads:
Quote
Throughout the years it has become a duty of each Flat Earth Society member, to meet the common round earther in the open, avowed, and unyielding rebellion; to declare that his reign of error and confusion is over; and that henceforth, like a falling dynasty, he must shrink and disappear, leaving the throne and the kingdom of science and philosophy to those awakening intellects whose numbers are constantly increasing, and whose march is rapid and irresistible. The soldiers of truth and reason of the Flat Earth Society have drawn the sword, and ere another generation has been educated and grown to maturity, will have forced the usurpers to abdicate. Like the decayed and crumbling trees of an ancient forest, rent and shattered by wind and storm, the hypothetical philosophies, which have hitherto cumbered the civilized world, are unable to resist the elements of experimental and logical criticism; and sooner or later must succumb to their assaults. The axe is uplifted for a final stroke - it is about to fall upon the primitive sphere of the earth, and the blow will surely "cut the cumberer down!"

It seems that all this lofty talk boils down to "let's debate stuff to death on a forum". That's fine by me, as I admit I'm here for entertainment. But I don't think that's very healthy for a society that "is dedicated to unraveling the true mysteries of the universe and demonstrating that the earth is flat and that Round Earth doctrine is little more than an elaborate hoax. "

To me it seems a case of the bark being bigger than the bite.
I don't want to believe.

None of these are "the size of a football field" nor do they require "a small power station" to operate. I'm sure these guys invested a bit of money but it's not a military/NASA size budget. No one is suggesting you can make these out of tin cans and string.

All this in the end is only another diversion anyway, since it has nothing to do with whether you can measure the distance to the moon with radio waves or not.

Thork your Wolfram calculation is entered differently than what was posted. You might want to refresh on the order of operations. BEDMAS!

2.55s/2*186,000mi/s

is different than

2.55s/(2*186,000mi/s)

Googleotomy's calculation is correct. He calculated the time it took for a radio signal to go to the moon and back (2.55s), divided it by 2 to get the average length of one leg of the trip (2.55s/2=1.275s), and then multiplied the result by the speed of light (1.275s*186,000mi/s=227,150 mi)

I have a hard time believing you did not know this.

Thork wins over a lot of FErs by making a post that appears to trump the OP.

Links no matter what they are to, seem to act as fact for whatever his rebuttal is.

Even though the main issues of the argument haven't even been broached, the thread is successfully derailed.

Whether it's a subconscious trait of FErs to derail a thread before any real debating begins or simply a trait of any person when they can't defend their beliefs, it just seems that's the way most threads go.  Enter sceptimatic and then you have nonsense debates that take all of the RErs time, much like n00bs take up a lot of FErs time.

Interesting theory. But I doubt it would be able to concentrate the luminance of the Earth and maintain the intensity that it does if it reflected the light in all directions.

And where does the light from the Earth come from ? From the sun ?  And if the light from the moon comes from the Earth doesn't that mean both the Earth and the moon reflect sunlight ?
The Sun is a focusing reflector of the infrared radiation coming from the Earth as a result of the UA reacting with the bottom of it.
