I agree with John on the need for more data:
Also the attached below suggests we might need to know more about any
location
selected on the moon.
How deep the dust
How rocky
How illuminated and when.
The differences between the poles and non poles areas.
See video of moon:
+ The Japan Aerospace Exploration Agency (JAXA) has released the
final still images taken by the onboard High Definition Television
(HDTV) from Kaguya, just before it completed its mission by impact-
ing the moon on June 11, 2009. An entire series of images were
taken with an interval of about one minute by the HDTV (Teltephoto)
while Kaguya maneuvered its way to impact in Gill Crater. See:

Hi Miles,
To get an idea about the difficulty to designe and build a transponder that
must work on the moon I suggest to carefully see the following links.
http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19720012254_1972012254.
pdf
If you have problems to get the above NASA report from internet I can send a
pdf file to you or to any people is interested but it is about 4 MB long
Also the following pictures and drawings are self explanatory.
http://www.myspacemuseum.com/alsep01.htm
After reading both the above papers you will realize that the task is very
hard viable by any amateur team.

Yes Exactly!
We need to form a proposal team that can evaluate the data to find out if an
EME-Repeater is viable.
Time is short.
First ask Experts if building a transponder for the Moon is feasible with
current technology.
If it were, How many Amateur radio operators would be able to afford such a
project?
We know the are hundreds of Hams, which have used EME at one time, or
another.
If we build a working transponder, how many more hams would have access to
and EME-Repeater?
Based on the number of users that could build an EME-Repeater link, we would
go ahead with the idea and take it to the next phase.
There no sense in building an EME-Repeater project if only a hundred people
would be able to access the EME-Repeater.
So if the project looks feasible and there is a big enough potential group
of Amateur Radio stations that would uses such a project, then we would
start talking to all of our contacts at NASA, ESA, RSA to see if we can get
some additional support to help with the project.
Thanks Miles

Hi All
?
My 1st Questions is -
?
What the reason of QUIETING in Echo-51 sat?
?
?
?
Google gave me a good link of k0nr
http://www.k0nr.com/rwitte/fmvhf.html
?
k0nr wrote
SIGNAL REPORTS
FM signal reports are often given in terms of receiver quieting. A strong
signal
will fully quiet an FM receiver, while a weak one will be quite noisy. A "Full
quieting" report is given to a signal which exhibits no background noise or
hiss. Signal reports are often given in terms of "percent quieting" to give
the
transmitting station a better idea of the signal quality.
Remember that when using a repeater there are two communication paths at work
--
the path from the transmitting station to the repeater and the path from the
repeater to the receiving station. Either one of these paths can exhibit noise
due to a weak signal. If the receiving station has a strong S-meter indication
but the transmitting station sounds noisy, the transmitting station is
probably
weak into the repeater. Remember that the signal strength indicated by your S
meter is due to the repeater and not the transmitting station.
A frequency modulated transmitter used on the VHF/UHF amateur bands should be
set for a maximum frequency deviation of 5 kHz with full modulation. Unlike
SSB
transmitters, the signal strength of an FM signal is independent of modulation
level. That is, a dead carrier produces just as much power as a fully-
modulated
signal. Excessive modulation of an FM transmitter does not improve the
reception
of the signal and often degrades it. On the other hand, inadequate FM
deviation
causes weak received audio. The level of audio heard on the receive end is
relatively independent of received signal strength. This means that changing
transmitter power does not affect the loudness of the audio at the receive
end.
?
?
What I have understood
??????????????????.
(FM signal reports are often given in terms of receiver quieting
A strong signal will fully quiet an FM receiver)
strong signal (from TX station or sat )
Quieting at receiver side (e.g. ground station)

Hello
To all you AO-7 fans. We appear to have a sick bird.? We should feel blessed
in having such a well performing satellite for several years, considering it
is older than some of it's users.? The audio is distorted and cw sounds bad,
running absolute minimum power.? Any thoughts or suggestions are solicited.

Hi!
I will be at the ARRL Arizona State Convention and Hamfest in
Williams, Arizona, on 17-18 July 2009 - a Friday and Saturday.
I'll have an AMSAT table in the main hall, and will give a
satellite-related presentation at 1100 local time on 17 July.
During these two days, WD9EWK will be on FM satellites and also
VO-52 for demonstrations (hamfest site is in grid DM35vg). More
information on the hamfest is available at:
http://www.arca-az.org/arca/main/convention.asp
After the hamfest, I will hit the road for a few days. Similar
to what I did last year after the Williams hamfest, except I will
venture further north into Utah. I'll make a loop through that
state, then head back toward Arizona so I'm home by the evening of
22 July. I have not finalized my route through Utah yet, but I
have some idea of how I will make that drive. I'll post more about
my travel plans in a week or so, and then post updates while I am
on the road.
As with last year's road trip and several other trips I've done
where I've been on the birds, I will be happy to send QSLs for
those working WD9EWK from wherever I operated from. I'll also
send QSLs to anyone who works me during the demonstrations from
Williams. Just drop me an e-mail after the trip with the QSO(s)
listed in there, and - if you're in the log - I'll send the cards
out.
73!

We had this discussion a while back on APRSSIG (I know, I started it!)
Unfortunately, the way Part 97 currently reads is that most pager
transmissions to an individual are illegal under ?97.111(b), as it is a
"one way" transmission that, in most cases, would not qualify under the
"legal" list.

I hardly consider myself a curmudgeon. I'd *love* to set up a local
pager network in the way you describe. The issue is that, according to
Part 97, it can't be used beyond QSTs, telemetry, or "necessary"
emergency communications. Could I get away with setting up such a
system? Likely. Do I foot to stand on when my local OO comes knocking?
Not so much.

This would be great. Can someone please seek a clarification or
modification of the rules from the FCC to allow this?

Ben,
I was the one the kind of threw the pagers out there "idea" I know I am not
the only one and not the frist. I myself had questions as to the legality of
it - as I understood part 97 it sends mixed signals as to weather or not it is
legal -
My basic problem was in useing it as a personal pager - there is a ham in MI
use has them linked to aprs and packet - he says that if a ham (how did he put
it). Starts the personal page to someone it is fine - but if it is an
automated thing then it is not
I asked him which part of part 97 he claims because it is digital
I think part 97 is vauge and vauge for a reason. My as I see it from a part 97
"legal" point of view setting a personal cap code probably would be pushing
your luck
However if you setup each pager with the same capcodes and send national and
local emergancy and dx cluster reports and other things of interest to
everyone it is probably legal as digital telemetery
I wrote a blog about it - http://73s.org/kd8bxp (the blog that says something
like I have an idea but is it legal).
>From the other post on this BB I see I am not the only one who is interested
in something like this
Maybe we can get everyone who is interested in a chat room or skype conferance
call or echolink or something and fire off ideas to each other - maybe even
get a paper written up for "offical submittion" to the fcc for clarification
Also feel free to look me up on my site http://www.HamOhio.com. Or follow me
on twitter.com/kd8bxp
I see this was not an orignal idea but I do think it is an idea who's time has
come and needs to be worked on

I hardly consider myself a curmudgeon. I'd *love* to set up a local
pager network in the way you describe. The issue is that, according to
Part 97, it can't be used beyond QSTs, telemetry, or "necessary"
emergency communications. Could I get away with setting up such a
system? Likely. Do I foot to stand on when my local OO comes knocking?
Not so much.

This would be great. Can someone please seek a clarification or
modification of the rules from the FCC to allow this?

Sometimes it pays to go on vacation (600+ back e-mail).
The lunar link analysis has been done on Amsat-bb
at least 4 or 5 times in the last ten years. I
have a spreadsheet program that can be used for
any point to point communication in space (plug in your own numbers)
http://www.kl7uw.com/MROCalc.xls
Since we assume to ride to the Moon with NASA
(manned flight) it could be buried on the Moon
with only antenna exposed (solves some of the
temperature and radiation issues). Make it the
emergency comm system for the astronauts like
ARISS provides on the ISS (selling point to
NASA). Make it a digital passband or
multi-channel system. NOT a single-channel FM
repeater like AO-51 (consider have the world's
hams trying to use that channel at the same time!).
Microwave only make sense. Maybe use the
CC-rider concept from Eagle. Now it has Emcomm
potential. as well. With the 2.5 second RTLT
time delay text modes make more sense. Digital voice at minimum.
30 to 50w uplink transmitter would do it (play with the calculator, above).
Try for 2-foot dish on the earth station. Moon
gravity is 1/6 earth and no wind (light weight
dish will work). Or perhaps a electronically
steared panel array. Auto-tracking by carrier
from NASA DSN tracking network (let them have 3-4 channels exclusive use).

I used AO-7 yesterday evening and all seems well except the normal AO-7
gargle. But when you take this in consideration and don't use to must power
or talk the fast is it still a nice bird to use.
