hi
I remember not too long ago fellow hams were polite and helpful
don't be discouraged
Bob, I don't use satpc32, but it might help if you specify if the
problem occurs strictly when you start satpc or you get the
noise when the computer is on (regardless of running satpc)
if the problem should occur when you turn on the pc, it is not
uncommon for pc's to throw out a lot of noise
disconnect any cables going from the rig to the pc does the noise
still occur?
if it does you have to experiment a bit to see if you can eliminate
the noise, you might have to try to buy a ac filter for the pc
array solutions makes one.
you may also have to try putting ferrits
(http://www.dxengineering.com/Products.asp?ID=182&SecID=152&DeptID=42
) on the cabling for your rig
you might want to google around and search the ARRL web site on
trying to mitigate pc noise, ultimately you may have to move
the pc
feel free to email me directly off the list i am not expert but
will try to help you

If the same Dell with all the old cables ( CAT, USB, etc ) worked without a
hiss then you need to check what changed. Start with grounding. One of the
cables may have lost the grounded shield. You may have rearranged your desk
and the cables run closer together. Maybe you always had this but usually
ran SATPC32 with the volume low. The key is "What changed since the last
time it worked okay for you?" Did you change the video resolution - if so
put it back temporarily. Did you change external speakers? Is it the same
with both internal and external speakers. If the external ones are noisy
then your amp and speakers are picking up RF.
Is the hiss on the Dell speakers or on the radio speakers? What changed
there? Cables, connectors, position. If on the radio, check that CAT cable
between the Dell and the Radio.
Try it without the CAT cable plugged in, the cable to your rotator
controller - you are removing antennas that my be picking up RF from your
video.
Load other programs, your browser, email client and whatever else you have
on there to see if the noise can be duplicated like SATPC32 then you know
for sure some RF from your video card if getting into the sound system.
It is a matter of removing or changing one item at a time. Don't do 2 or 3
changes at the same time because you won't know which did the fix.
Think like Sherlock Holmes and eliminate potential causes.
Good luck.

Thanks to all for being patient while I operated portable from DM92ra on the
2055Z AO-27 pass and the 2255Z AO-51 pass this afternoon.
I worked 22 stations and I know there were a few others calling, but it's
hard to get a call in edgewise sometimes.
I used an Arrow with a Kenwood TH-F6A on the uplink and my trusty old IC-W2A
on the downlink. I have the Arrow without the built-in diplexer, so that
worked out pretty well.
DM92ra is about 48 miles north of my QTH in the middle of nowhere (there's a
lot of that in WTX).
I'll QSL to all who I worked, no need to QSL me or send an SASE. Monday's
a U.S. federal holiday (Columbus Day), so they'll go out Tuesday.
Tomorrow (11 Oct), I plan to go 35 miles south to DM90rx. There are no
decent AO-51 passes during the window I can make it, but there are two good
passes of AO-27 and SO-50.
I'll try to make the 1827Z pass of SO-50 and the 2025Z pass of AO-27. Those
are my AOS times.
Again, I'll QSL all who I work.

Peter,
You have to switch the downlink band on the FT-736R in the SAT mode
before you engage the CAT to be the proper downlink band, using the REV
key. Might that be the problem?

spacecraft platform that includes propulsion, power, thermal control,
environmental control, avionics, communications, thermal protection,
flight
software, guidance, navigation and control, entry, descent and landing,
and
recovery.
The user conference is an opportunity for potential customers to explore
DragonLab's capabilities, as well as present customer-specific interests
and
requirements. The agenda includes an overview of the Dragon spacecraft,
concept of operations, payload accommodations and cost parameters.
DragonLab is an alternate configuration of SpaceX's Dragon spacecraft
which,
along with the Falcon 9 launch vehicle, has been contracted by NASA to
provide
cargo resupply services to the International Space Station as early as
2010.
To express interest in attending the user conference, visit

BID: $ANS-284.03
RADIO LAW: SENATE BILL INTRODUCED TO STUDY HAM RADIO EMCOMM
A companion bill to the Amateur Radio Emergency Communications
Enhancement
Act of 2009 was introduced in the U.S. Senate on Tuesday, October 6
by Connecticut Democrat Joe Lieberman and Maine Republican Susan
Collins.
Titled Senate Bill 1755, it carries the same name as the House measure
introduced this past April by Representative Sheila Jackson-Lee. The
bill,
if passed, would direct the Department of Homeland Security to undertake
a
study on emergency communications with an emphasis on the role that ham
radio operators play.
S 1755 points out that "There is a strong Federal interest in the
effective
performance of Amateur Radio Service stations, and that performance must
be
given support at all levels of government; and protection against
unreasonable regulation and impediments to the provision of the valuable
communications provided by such stations.
Introduction of S 1755 is the result of many months of groundwork laid
by
the American Radio Relay League and appears to be directly based on the
basis and purpose of the service. This as outlined in Section 97.1 of
the
FCC rules. (ARRL)

Rogue satellites to be cleared from Earth's orbit by German robots
German-built robots are to be sent into Earth's orbit to repair 'dead
satellites' or push them into outer space, according to a report in
Sunday's Guardian newspaper.
Robots that rescue failing satellites and push 'dead' ones into outer
space should be ready in four years, it has emerged. Experts described
the development by German scientists as a crucial step in preventing a
disaster in the Earth's crowded orbit.
Last year it was reported that critical levels of debris circling the
Earth were threatening astronauts' lives and the future of the
multibillion-pound satellite communications industry. But senior figures
at the German Aerospace Centre (DLR) told the /Observer/ they have been
given the go-ahead to tackle a crisis that will come to a head in the
next five to 10 years as more orbiting objects run out of fuel.
Their robots will dock with failing satellites to carry out repairs or
push them into "graveyard orbits", freeing vital space in geostationary
orbit. This is the narrow band 22,000 miles above the Earth in which
orbiting objects appear fixed at the same point. More than 200 dead
satellites litter this orbit. Within 10 years that number could increase
fivefold, the International Association for the Advancement of Space
Safety has warned.

I'm sure you are joking with the AO-40 reference. No one is interested
in helping amateurs put new sats into orbit much less fixing one of our
broken ones. :-)
