Surely that's the minimum power to keep things alive *when it's in emergency 
mode*.

Oh, and top-posting is really annoying.

[amsat-bb] Is Prospero still TX'ing?

[John Heath]

Is Prospero still transmitting?

Sometime ago, I think in 2007 the BBC TV program Coast was on the Isle of White 
where there had been a test stand for rocket testing. 

They talked about Prospero and had a short piece with some people trying to 
hear 
it with a small yagi. Apologies but the memory is a bit hazy.

Subsequently I spent quite a few hours listening for it with a tower mounted 
5el 
X yagi, an up to date set of keps, and an FT847 - after several days, nothing 
heard.

Although funding to command the satellite ceased in 1996 the Prospero real-time 
oribtal tracking page says it was heard in 2006.
http://www.vk3ukf.com/Space/GadgetSatProspero.htm

I would image now the Mullard Space Science Laboratory in Surrey are attempting 
to command the satellite again the 137.560 MHz beacon would become operational 
if enough of the satellite is still working.

Given the 40th anniversary of this historic UK spacecraft takes place in 
October I would expect the media would be very interested if any amateur 
succeeded in receiving it in the coming weeks.

Audio recordings of the 0.3 watt phase modulated signal with PCM at 2048 bit/s 
from Prospero on 137.560 MHz can be heard on the Sounds from Space website of

Stuffing capacitors is a standard technique in the restoration of old radios. 

If anyone had the time to waste they'd probably find the original of that 
picture on one of the many US websites dealing with restoration work.

The picture was circulated around 2007/8 in an email attempting to smear 
components manufactured in China.

I have a copy of that program, It was BBC "Coast" Series 2, Episode 1 
Dover to Isle Of Wight.
Its right at the end of the episode. It tells the story of Prospero, 
and shows a receiver connected to a small yagi, and the satellite
is audible. They use an AR8600 RX, and the displayed frequency is 
137.5610 Wide FM


Don't know about sharing, the whole episode avi is 700+meg! + copyright issues.

[amsat-bb] Magnetic North vs True North

[Carl Rimmer W8KRF]

The earlier discussion on this topic caused me to think about my setup.  
I know the tracking programs use True North; my question:  If my 
declination is 8 º 6' West, is my true north East or West of Magnetic 
North. I am currently setup to where my True North is 8º East of 
Magnetic North.  I have looked a various sights on the Internet but I 
have always had a problem wrapping my thick brain around this topic.

[amsat-bb] New Views - Apollo Landing Sites

[Clint Bradford]

RELEASE: 11-289

NASA SPACECRAFT IMAGES OFFER SHARPER VIEWS OF APOLLO LANDING SITES

GREENBELT, Md. -- NASA's Lunar Reconnaissance Orbiter (LRO) captured 
the sharpest images ever taken from space of the Apollo 12, 14 and 17 
landing sites. Images show the twists and turns of the paths made 
when the astronauts explored the lunar surface. 

At the Apollo 17 site, the tracks laid down by the lunar rover are 
clearly visible, along with the last foot trails left on the moon. 
The images also show where the astronauts placed some of the 
scientific instruments that provided the first insight into the 
moon's environment and interior. 

"We can retrace the astronauts' steps with greater clarity to see 
where they took lunar samples," said Noah Petro, a lunar geologist at 
NASA's Goddard Space Flight Center in Greenbelt, Md., who is a member 
of the LRO project science team. 

All three images show distinct trails left in the moon's thin soil 
when the astronauts exited the lunar modules and explored on foot. In 
the Apollo 17 image, the foot trails, including the last path made on 
the moon by humans, are easily distinguished from the dual tracks 
left by the lunar rover, which remains parked east of the lander. 

"The new low-altitude Narrow Angle Camera images sharpen our view of 
the moon's surface," said Arizona State University researcher Mark 
Robinson, principal investigator for the Lunar Reconnaissance Orbiter 
Camera (LROC). "A great example is the sharpness of the rover tracks 
at the Apollo 17 site. In previous images the rover tracks were 
visible, but now they are sharp parallel lines on the surface." 
At each site, trails also run to the west of the landers, where the 
astronauts placed the Apollo Lunar Surface Experiments Package 
(ALSEP) to monitor the moon's environment and interior. This 
equipment was a key part of every Apollo mission. 

It provided the first insights into the moon's internal structure, 
measurements of the lunar surface pressure and the composition of its 
atmosphere. Apollo 11 carried a simpler version of the science 
package. 

One of the details that shows up is a bright L-shape in the Apollo 12 
image. It marks the locations of cables running from ALSEP's central 
station to two of its instruments. Although the cables are much too 
small for direct viewing, they show up because they reflect light 
very well. 
The higher resolution of these images is possible because of 
adjustments made to LRO's orbit, which is slightly oval-shaped or 
elliptical. "Without changing the average altitude, we made the orbit 
more elliptical, so the lowest part of the orbit is on the sunlit 
side of the moon," said Goddard's John Keller, deputy LRO project 
scientist. "This put LRO in a perfect position to take these new 
pictures of the surface." 

The maneuver lowered LRO from its usual altitude of approximately 31 
miles (50 kilometers) to an altitude that dipped as low as nearly 13 
miles (21 kilometers) as it passed over the moon's surface. The 
spacecraft has remained in this orbit for 28 days, long enough for 
the moon to completely rotate. This allows full coverage of the 
surface by LROC's Wide Angle Camera. The cycle ends today when the 
spacecraft will be returned to its 31-mile orbit. 

"These images remind us of our fantastic Apollo history and beckon us 
to continue to move forward in exploration of our solar system," said 
Jim Green, director of the Planetary Science Division at NASA 
Headquarters in Washington. 

LRO was built and managed by Goddard. Initial research was funded by 
the Exploration Systems Mission Directorate at NASA Headquarters. In 
September 2010, after a one-year successful exploration mission, the 
mission turned its attention from exploration objectives to 
scientific research in NASA's Science Mission Directorate.

Hi Carl, W8KRF

Using a simple magnetic compass I suggest you to look at the Magnetic
North and then compare the above North position with that of the Pole
Star that indicates the True North.

To find the Pole Star in the True North direction in a clear sky is very
easy because the Pole Star elevation in the sky is equal to your Latitude.

With the above informations you can easily establish  if your True North
is 8º 6' East or West of Magnetic North.

FYI Magnetic declination, sometimes called magnetic variation, is the
angle between magnetic north and true north. Declination is considered
positive east of true north and negative when west.

Magnetic declination changes over time and with location.

Hi,

Looked to see what I had on Prospero from the previous attempts to hear it.
This might be of interest. I only have this fragment, not the entire paper, or 
section 4.4  more's the pity.
73 John G7HIA

Accession Number : AD0734634
Title :   Orbital Operations Handbook for the X3 Satellite.
Descriptive Note : Technical rept.,
Corporate Author : ROYAL AIRCRAFT ESTABLISHMENT FARNBOROUGH (ENGLAND)
Personal Author(s) : Adams,V. W.
Report Date : AUG 1971
Pagination or Media Count : 63
Abstract : The X3 satellite, the first technological spacecraft in the British 
National Space Programme, is scheduled to be launched on a Black Arrow vehicle 
in late 1971. The spacecraft carries experiments to investigate performance of 
solar cells, characteristics of thermal surfaces, micrometeoroid flux and 
performance in orbit of a hybrid electronics package: section 4.4 gives 
details. 
In addition newly developed data, telemetry, telecommand and power system will 
be tested in orbit. The micrometeoroid flux experiment has been contributed by 
the University of Birmingham, England. (Author)

Hi Vince, KB7ADL

I too have always used the Polaris and found this procedure very
satisfactory for the accuracy and backlash of the gears in our amateur
rotator for VHF and UHF antennas.

For the S band at 2400 MHz and a 1.2 meter dish to calibrate the Azimuth and
Elevation I use the Sun Noise but the rotators have negligible backlash and
the position readout can estimate +/- 0.25°

[amsat-bb] Attending the ARRL SW Div Convention Saturday?

[Clint Bradford]

If you are attending the ARRL SW Division Convention in Torrance this Saturday 
...

AND if you've been thinking of purchasing either an Elk 2M/440L5 Log Periodic, 
an 
Arrow 146/437-10WBP, or Premier AL-800 ...

Then have I got a couple deals for you!

In conjunction with Ham Radio Outlet - Anaheim, mention "K6LCS Sat Special" at 
the HRO booth at the show, and get a couple bucks off the show price on the 
AL-800 and/or the Arrow ... and an impressive price of $82.95 for the Elk!

AND THERE'S MORE! Bring your receipt from the purchase of a Yaesu FT-60R that 
you purchased from the fine folks at the HRO booth on Saturday to me - and the 
first four who do so will be handed a Smiley 270A antenna! I will be at the 
show 
from 7:30AM to dinner time on Saturday. Find me working the sats from the 
parking structure at the times posted all over the event. Or see me right 
before, 
during, or after my satellite show in Suites 9-11 which begins at Noon. Go 
ahead 
and interrupt the session - I only have FOUR of these great antennas to give 
away!

Clint, K6LCS

[amsat-bb] Re: Magnetic North vs True North

[Dave Guimont]

Carl, an easy way to remember is:

True (Variation, also called declination) 
Magnetic (D deviation, compass error) Compass add 
west, (or add east going the other way)


Two Virgins Make Dead Company add west

The V is Variation, also called declination M 
Magnetic deviation(compass error) Compass add west.



The earlier discussion on this topic caused me to think about my setup.
I know the tracking programs use True North; my 
question: If my declination is 8 º 6' West, is 
my true north East or West of Magnetic North. I 
am currently setup to where my True North is 8º 
East of Magnetic North. I have looked a various 
sights on the Internet but I have always had a 
problem wrapping my thick brain around this topic.


Thanks,
--

Ok, poking around some more, I tried running it directly in Wine (vs starting 
it with Cx Office).  Now it runs!

Thanks for the encouraging words; they helped.
