i watched this. it was very interesting and eye opening
What is AM medium wave reception like on the moon?
Can stations from earth be heard up there?
Or, does the ionosphere block medium wave frequencies from passing into space?
What about the other way around? If medium wave transmitter systems were built on the moon could they be heard on earth?
Why don't "earth", "moon" and "sun" begin with capital letters?
What is AM medium wave reception like on the moon?
A:Non Existent
Can stations from earth be heard up there?
A:NO, only some possible short-wave but yes to VHF/UHF
Or, does the ionosphere block medium wave frequencies from passing into space?
A:Yes. see the prevoius answers
What about the other way around? If medium wave transmitter systems were built on the moon could they be heard on earth?
A: NO
Why don't "earth", "moon" and "sun" begin with capital letters?
A: Informal nouns. To make them formal begin with "The." The Moon, The Earth, The Sun....
FM stands for "Full Moon," so if an FM (frequency modulation) station were built on The Moon it would be an FM FM station, because it would come in best during times around a full moon.
Oh, F.C.C., please reserve 87.7 MHz for my Moon FM FM station, o.k.?
My rocket drone is already being sketched to get the equipment up there.
During hours when earth and moon are face-to-face it should cover half the globe with X Watts.
How many Watts will we need?
I think it was in QST, one of the ham radio
monthly magazines. Around 1970 or so,
a ham radio dude in the U.S. received several transmitters
(good clear audio) from one of the Apollo missions that had landed
on the moon. This was in the 1 to 2 GHz range
(I think.) I also believe he heard some transmitters
that the astronauts had left behind after they had
taken off for the journey back to Earth.
This is what I remember. I also remember he
used a huge dish antenna. Now to try to find
info to verify this and get the details.
I do think it happened, though. I seemed to
remember telling my parents, and they told
me to do my homework.
As for the subject of extraterestrials, I find
this is be interesting and although I haven't
watched the link Robert found, I probably will.
I could talk about that for hours, but I just
heard an interesting theory - I have no opinion
on it - I just think it's a fun thought.
I read somewhere, that space is so vast and
huge, that in the whole time the human race
is alive, the mathamatics (when solved for
the answer)... Well, the math says that
there is a probabilty that the human race
will come into contact with a certain number
of alien races. That number turns out to be
2 1/2. So, it's really just 2. Of course, it's
fun to think about this stuff. I don't want
to open a can of worms about this - but that
low number sort of made me feel a little
creepy. If you take it as a fact, that means
that space is really really huge, and even
advanced races who have figured out
"star-drive" or "worm-hole-drive" or
"dimensional-drive" (????) or whatever are really far away.
REALLY far away. More distant than
our minds can really grasp.
I find that to be creepy.
Now to check on that amateur
radio operator receiving signals
from the moon.

I have to do more reading, but some
ham radio enthusiasts and other separate
people, who were in observitories with
high gain antennas, did hear some of
the Apollo missions. Also, some amateur
astronomers saw the Apollo spacecraft
over the moon (the moon was behind
the spacecraft from our point of view.)
That's a big deal as far as I'm concerned.
When I was young, and a ham, I listened
to the ham radio satellite OSCAR 7, and
I sucessfully transmitted a signal that was
relayed by OSCAR 8 (2 meters up, 10 meters down.)
OSCAR stands for Orbiting Satellite Carrying Amateur Radio.
The receiver was a Hammarlund HQ-170C. Oscar 8 was
really really loud on the receiver. The transmitter was a
Heathkit, uh, I don't remember - but it was huge and
green with lots of chrome, with about 800 or 900 volts
on the plates of the tubes and I was afraid to be near it.
Especially when somethiing went wrong and there was
a huge BANG. I remember my father yelling down from
the upstairs, "Γre You Alright?" Oh gosh, it was a
Heathkit Senecca. A more terrifying piece of ham gear
I have never seen in my life! (at age 19 - and maybe NOW too.
It was supposed to put out 50 or 100 watts on 2 meters.
( I don't know.) I didn't have anyway to test it so
it put a 2 meter "rubber duck" antenna into the
SO-239 RF output jack on the back of the thing!
I was lucky in that sense. The rubber duck had
a PL-259 plug that fit the SO-239.
Telegraph key in to test for RF carrier. Key down.
Lots of hum. 900 volts on the plates. Small sounds
of metal expanding and the strain of components
because the transmitter hadn't been used in a
while. Unknown, uncomfortable (to me) sounds.
Then I smelled something burning.
Key up.
I looked around at the back of the
transmitter. The rubber duck antenna
was melting and dripping all over the desk!
Yeah, the transmitter worked, but it was
a long time before I got the guts to try and
transmit the 2 meter signal up to OSCAR 8.
And, yup, when I sent it up, it did come back
down in the 10 meter band. I heard it on the
HQ-170C. Very very unstable carrier. That
was enough. I didn't do it again. Years
later, way after I had moved out of my
parent's house, the Senecca was still sitting
in the basement. I had taken all of the
"good" radios, and had left the scary one
in a cellar corner.
Then one Thursday morning the trash collection
garbage truck came down the street. My father
had put the Senecca out for the trash. The garbage
collection guy saw my dad with the transmitter.
He asked my father if it was a CB linear amplifier!
My dad said he didn't know if it would work but
WHY NOT TRY IT! OH MY MY... KABLAMM????
Oh man - - I have heard other space satellites in my
life, but nothing ever beat THAT experience!

During the 1970s I produced audio-visual (A/V) programs for the Lutheran Church, and a reverend from Headquarters came to my home studio with scripts and materials and we became good buddies.
He seemed very regular, a conventional minister, ordinary guy.
Until he confided in me that aliens from space had infiltrated the government of the United States and that many key politicians and military people were, in fact, of the alien kind.
He was not kidding then and I am not making this up nor kidding now.
He told me he had contacted the air force about this, but they were trying to ignore and dismiss his claims.
So I slapped a tape on a recording machine and started interviewing the reverend, but he greatly softened his story based on his wish to someday publish what he knew in book form.
I may still have the tape, the basement is packed with stored magnetic tape, but my recording playback machine is broken.
I have tried to locate this man recently but am not sure if he's still around.
I do recall that he said the aliens were very much at home in a radioactive environment, and now we find that nuclear power and nuclear accidents are poisoning the planet for humans, but not for "them"?
