I've not had that trouble w/736, but I do have the "Technical Supplement"
for the FT-736R, which has block diagrams and schematics.
The audio makes it way thru several boards and connectors on it's way
around to the speaker. I can easily scan a few relevant pages and either
email or post on my web site if you are so inclined to dig into it.
Might check the level at the front headphone jack (and exercise the switch
contacts inside the jack) as well as the external speaker jack on the back.
I've had output interruptus due to cracked solder joints on the external
spkr jack before. Aged output blocking capacitors often result in lower
sound levels as time goes by. I've fixed many a VHF scanner that way.

Alan,
First you might check the headphone jack, it disconnects the speaker when
the phones are plugged in and the contacts may be dirty. Also try an
external speaker as the one inside may have lost part of its cone.
Most likely with 3+ decades of age, I suggest you replace all of the
aluminum Electrolytic capacitors, as they most likely have dried out over
the years. They are rated for a decade of service and three is pushing it.
As they are all of the same age replacing only the open one will begin to
happen at an increasing rate, so best to do them all it once.
Art, KC6UQH

In 1966, the Soviet Luna 9 survived a near-vertical landing on the Moon
with a speed of about 50km/h (approx 30mph). It used an inflated bag to
cushion the impact.
In 1997, America's Pathfinder rover used a similar technique and touched
down on Mars with a similar vertical speed. It was designed to take an
impact about fifty percent greater than it actually experienced.
It would be possible to land something at a high velocity, providing the
vertical component is not much more than that of Luna 9 or Pathfinder.
Horizontal speed can be killed by rolling and bouncing, as happened with
Pathfinder when it struck the surface at an angle of about 50 degrees.
The downside of this approach comes in the form of any significant
vertical obstruction such as a large boulder or a cliff face.

What speed do you think would be max survivable speed for a landing on
the moon for a robot, or comm system?

That's exactly as I was thinking.
With no atmosphere, the moon, you could in theory orbit with a decaying
orbit until it was only as high as the surface, (But of course the
mountains are a problem.)
But Some numbers were crunched,, and say a lander was orbiting, and
slowed down just the right amount that it began to decay. ever soo
slowly, in theory of it was a perfect sphere and smooth as glass the
thing could orbit inches above the surface true?
But the moons gravity is very un even as well as the surface.. But
give the sphere and smooth thought,
It could orbit and eventually land at a speed of, 1.68 km per second or
slightly over 6000 MPh! don't think it could survive.
Oh well..

CAPE CANAVERAL, Fla. - Two big communications satellites collided in the
first-ever crash of two intact spacecraft in orbit, shooting out a pair
of massive debris clouds and posing a slight risk to the international
space station.
NASA said it will take weeks to determine the full magnitude of the
crash, which occurred nearly 500 miles over Siberia on Tuesday.
"We knew this was going to happen eventually," said Mark Matney, an
orbital debris scientist at Johnson Space Center in Houston.
NASA believes any risk to the space station and its three astronauts is
low. It orbits about 270 miles below the collision course. There also
should be no danger to the space shuttle set to launch with seven
astronauts on Feb. 22, officials said, but that will be re-evaluated in
the coming days.
The collision involved an Iridium commercial satellite, which was
launched in 1997, and a Russian satellite launched in 1993 and believed
to be nonfunctioning. The Russian satellite was out of control, Matney said.
The Iridium craft weighed 1,235 pounds, and the Russian craft nearly a ton.
No one has any idea yet how many pieces were generated or how big they
might be.
"Right now, they're definitely counting dozens," Matney said. "I would
suspect that they'll be counting hundreds when the counting is done."

Dieter Schliemann, KX4Y SK
AMSAT News Service Bulletin 046.02
>From AMSAT HQ SILVER SPRING, MD.
February 15, 2009
To All RADIO AMATEURS
BID: $ANS-046.02
Frank Bauer, KA3HDO wrote on behalf of the Amateur Radio on the
International Space Station (ARISS) program, "It is with great
sadness that I announce the passing of Dieter Schliemann, KX4Y."
Frank continued, "Those that knew Dieter recognized that he was
a 'class act', a great gentleman and colleague who will be sorely
missed by all. Dieter was instrumental in leading and supporting
many key activities in AMSAT and on the ARISS program."
For ARISS, Dieter led the school contact IRLP/Echolink initiative.
Through this amateur radio VOIP system, Dieter and his team substan-
tially extended the reach of the school contacts. And through his
efforts, tens of thousands of school students and ham radio operators,
world-wide, could listen to other school contacts, enhancing education
and giving all a better understanding of what it is like to live and
work on the ISS.
Frank remembers, "Dieter's diplomacy, teambuilding skills and atten-
tion to the details were impeccable and were well respected within
the team. He rose to the challenge when I asked him to lead the IRLP/
Echolink team. At the time, there were strong, divergent opinions on
the use of IRLP and Echolink on ARISS. He singlehandedly developed
a cohesive team that is producing great results and are enjoying
working together.
Over the past couple of years, Dieter fought a long and courageous
battle with cancer. A month ago, all of us thought he was on the road
to recovery. Unfortunately, that did not come to pass. Through it all,
Dieter remained the gentle, caring person that we all have grown to
love. And during his illness, he remained dedicated to his AMSAT and
ARISS causes and responsibilities. When he received the surprising
news from the doctors that he had only two weeks to live and despite
being weak from a long hospitalization, Dieter got on the e-mail and
worked a transition plan to ensure the IRLP/Echolink capabilities on
ARISS continues. What a great, compassionate, and loving human being!"
Frank first met Dieter behind the AMSAT Booth at Dayton, where he was
one of the mainstay individuals supporting AMSAT efforts at the Ham-
vention. Reflecting on Dieter's support to AMSAT, AMSAT Board Member
Gould Smith, WA4SXM, stated, "Two years ago Dieter told me that the
only reason he came to Dayton was to work in the AMSAT booth and to
talk with people about AMSAT". And he supported AMSAT in many other
ways, including his efforts as an Area Coordinator, where he mentored
a countless number of satellite enthusiasts. We are eternally grateful
for all Dieter has done for AMSAT and the ARISS program. And we will
miss him dearly."
AMSAT 20 Meter Net Control, Keith Pugh, W5IU remininsced, "My memories
of Dieter started during the AO-10 and AO-13 heyday. Dieter was an
excellent example of the ideal contributor to our marvelous hobby. He
constantly provided positive ideas and assistance for every phase of
the AMSAT and ARISS efforts. Never complaining, always jumping in and
doing what he suggested - not saying 'why don't you do this.' He will
be truly missed by everyone and deserves a special place in Amateur
Radio Heaven."
Frank concluded, "On behalf of the ARISS and AMSAT teams, we wish to
express our deepest sympathy to the Schliemann family and friends.
We think of especially his wife Tina and his good friend Ron Arsenault,
N1NYR, who helped Dieter and the Schliemann family throughout Dieter's
long illness."
Alan Sieg WB5RMG went to the visitation and described his experience,
"This evening I introduced myself to Dieter's wife Tina. We had never
met. When she saw my AMSAT badge she grabbed onto my hand and held it
for at least 10 minutes, like we were long-lost friends. She said she
was so glad that AMSAT could come to the visitation, and went on to
tell me about all the wonderful email and phone calls she has received
from all over the world. She understood what AMSAT meant to Dieter, and
was so proud that the people of AMSAT recognized what a good man he was.
She asked me to let everyone know how thankful she was that Dieter had
so many wonderful friends ... Thank You All" from Tina"

February 15, 2009
To All RADIO AMATEURS
BID: $ANS-046.03
Updates from www.kp5.us indicate that at least part of the team is now
on Desecheo, and will soon begin HF operations as K5D. Thanks to the
support of AMSAT-NA, the team is equipped with a Kenwood D7 HT and Arrow
antenna, as well as training on using the FM satellites. AMSAT-NA would
like to thank Doug Faunt N6TQS, Tim Lilley N3TL, and Patrick Stoddard,
WD7EWK for their generous donations of equipment for this and future
DXpedition, as well as Keith Pugh, W5IU for training assistance.
Satellite operation is not expected to begin until the second half of
the DXpedition, and then only on an as available basis. A second
repeater on AO-51 (145.88/435.150) will be activated on February 16th
and reserved -only- for contacts with K5D while within sight of the
island. K5D may be active on either AO-51 repeater, SO-50 or the ISS
voice repeater modes if available. Operation on the transponder
satellites is not expected unfortunately. Outside of range of Desecheo,
users are encouraged to operate under the standard AO-51 QRP rules.
These guidelines are 10 watts output or less, to omnidirectional or
handheld antennas only. Telemetry collection operations on AO-51 will
occasionally interrupt the 435.150 downlink on US west coast passes not
in range of Desecheo.
Users attempting contact with K5D should be aware the the DXpedition
does not wish to exchange grid squares during the QSO in order to allow
more operators the chance for a QSO. Their grid square is FK68, same as
most of Puerto Rico. Please be courteous and limit yourself to one QSO.
Logs are expected to be available online at http://www.kp5.us/ . Many
prolific DXpeditioners are on this trip, and a positive experience with
satellite may result in increased participation by future expeditions.
Good Luck on working a new one on satellite!

Listen for KAGAYAKI Satellite
The KAGAYAKI satellite has not been heard since it was launched
with Japan's January 23 GOSAT satellite. KAGAYAKI was to transmit
morse code on FM after separation from the H-2A booster.
If operational KAGAYAKI should be tranmitting morse code on FM
or 9600bps packet at 437.375MHz. The command team thinks the sat-
ellite'soutput power may very low because the antenna or solar
panel has not extended properly. Ground controllers have been
searching for a downlink signal using a spectrum analyzer.

Amateur Radio on the International Space Station (ARISS) Status Report
February 9, 2009
1. Upcoming School Contacts
An Amateur Radio on the International Space Station (ARISS) contact was
planned & completed for Istituto Comprensivo Pietrasanta1-Scuola
Secondaria 1? Grado "Padre Eugenio Barsanti" in Pietrasanta, Lucca,
Italy on Tuesday, February 10 at 10:24 UTC. Students have been learning
about the planets, planetary systems, rocket technology and radio
communications. They have applied their knowledge of English in writing
and rehearsing space related questions for the astronaut. They have
studied the history of spaceflight and have written essays on space
related topics. They have also learned about world geography and have
developed cooperation and teamwork skills.
An Amateur Radio on the International Space Station (ARISS) contact was
scheduled with Alexandroupolis School of Special Education and 11th
Alexandroupolis Primary School in Alexandroupolis, Greece. The contact
took place on Wednesday, February 11 at 07:43 UTC. Astronomy and amateur
radio lectures were given in preparation for the event. Special
attention has been given to the role of humanity and science and to the
every day life of an astronaut. The ISS courses have been based on ESA's
education tool "ISS Education Kit."
2. Canadian Contact Successful
On Monday, February 2, students from Humber College Institute of
Technology and Higher Learning in Toronto, Ontario, Canada participated
in an Amateur Radio on the International Space Station (ARISS) contact.
Approximately 100 students gathered in the lab where the radio gear was
built and watched as students posed 12 questions to Sandra Magnus,
KE5FYE. There was national coverage of the event and it was broadcasted
on morning television and radio - Canada AM (CTV Network). The Toronto
Star and Toronto Sun were also present. The audience reached in Toronto
was estimated to be over 3,000,000.

Subject: [amsat-bb] KP5 Desecheo DXpedition on satellite
Date: Thu, 12 Feb 2009 17:46:08 +0000
Updates from www.kp5.us indicate that at least part of the team is now on
Desecheo, and will soon begin HF operations as K5D. Thanks to the support of
AMSAT-NA, the team is equipped with a Kenwood D7 HT and Arrow antenna, as
well as training on using the FM satellites. AMSAT-NA would like to thank
Doug Faunt N6TQS, Tim Lilley N3TL, and Patrick Stoddard, WD7EWK for their
generous donations of equipment for this and future DXpedition, as well as
Keith Pugh, W5IU for training assistance.
Satellite operation is not expected to begin until the second half of the
DXpedition, and then only on an as available basis. A second repeater on
AO-51 (145.88/435.150) will be activated on February 16th and
reserved -only- for contacts with K5D while within sight of the island. K5D
may be active on either AO-51 repeater, SO-50 or the ISS voice repeater
modes if available. Operation on the transponder satellites is not expected
unfortunately. Outside of range of Desecheo, users are encouraged to operate
under the standard AO-51 QRP rules. These guidelines are 10 watts output or
less, to omnidirectional or handheld antennas only. Telemetry collection
operations on AO-51 will occasionally interrupt the 435.150 downlink on US
west coast passes not in range of Desecheo.
Users attempting contact with K5D should be aware the the DXpedition does
not wish to exchange grid squares during the QSO in order to allow more
operators the chance for a QSO. Their grid square is FK68, same as most of
Puerto Rico. Please be courteous and limit yourself to one QSO. Logs are
expected to be available online at http://www.kp5.us/ . Many prolific
DXpeditioners are on this trip, and a positive experience with satellite may
result in increased participation by future expeditions.
Good Luck on working a new one on satellite!

Hi thanks for reading this message,
I am planning to buy a Yaesy FT-847.
What are the experiences with this set when it comes to working with
satellites. I like to hear your experiences.
What are the thinks to look at when buying one second hand?
Hope to here from you.

The most important thing about buying a used FT-847 is to make certain is
has the bi-directional CAT CPU. The first ones produced did not, which
makes them nearly useless with tracking software. Years ago Yaesu did
updates free of charge, but there are a few around which have the original
chip. It isn't something you can fix at home.

Are you asking the mechanical engineers on the list for a SWAG
(scientific wild-assed guess) for an unknown structure, or do you have
at least bare minimum specifications of size and strength of a known
structure to work from?
I'm not a mechanical engineer, but even I can tell that the question
itself needs a lot more work than was put into it.
A two pound block of steel with no useful electronics on board would
likely "survive" a lot better than a fragile radio device or robot,
for example. But the block of steel won't DO anything useful.

What would cause it to "decay" with no atmosphere?
