I don't use SATPC, but will take a shot.
Googling: Ole "error" 8004503a reveals a lot of text to speech problems with
windows. 1) Does Satpc use speech? If so maybe you have a missing speech
driver. 2) Since the error is in German, do you have languages set up
correctly in the OS? perhaps that is problem.

Hello Nick,
Probably the Microsoft Text-to-Speech software is missing on your system
after the hard drive failure. The "Voice Announcement" feature of SatPC32
reqires these files to be installed on the PC. You can download the files
for free, see the following links.

See also the FAQs file on my website www.dk1tb.d e (English page
"Downloads").
Recently I myself got the same message after I had reinstalled Windows XP
from the recovery CD. The CD didn't install a soundcard driver for a newer
soundcard and I got no sounds at all from Windows XP.

> ISS SSTV Operations Planned for October 12
> from 18:00-21:00 UTC. This is your opportunity...
Due to hightened interest to the general Ham radio community for
this mission, I again suggest that all Shuttle Audio
Retransmission Faclities consider adding an old TNC and
144.39MHz APRS beacon to their system. This TNC will alert all
surrounding mobiles (with APRS display radios D7, D700, D710,
VX8R, HAMHUD's, etc) that the retransmission is on the air and
what frequency to tune.
Just load the correct beacon text, set the rate to 1 minute and
connect the TNC's XCD (external carrier detect) to the re-trans
PTT line, then whenever the re-trans is on the air, then a 1
minute announcement beacon will show up on all surrounding
radios.
You may have to invert the sense of the XCD line. Here is a web
page on this APRS local alert system:
www.aprs.org/On-Air-beacons.html
I appologize for repeating myself, but no sense in adding this
system after the Shuttle is back on the ground! Now's the time!
Here Is how it can look on the front panel of an APRS radio to
mobiles in the area:
+------------+
| 147.45NAN |
| SAREX ReTX |
| SSTV ops |
| Goddard |
+------------+
Where 147.45NAN is the retrans freq for the WA3NAN radio club at
NASA Goddard, for example.
A nice reminder that HAM Radio is again active in SPACE!

Hi all,
Thanks to Bob for all of the information in helping keeping amateur radio
alive especially with respect to the
our interest in satellites.
But just a note to remind any readers that the frequency that Bob refers to
for the APRS, is of course for the
operations in the USA. - Bobs web pages which he refers to "Do" of course
highlight this.
Thank you again Bob for all of your time and effort in putting out so much

If, like me, you're out at work for the ISS passes, then it's still possible
to record the SSTV and other modes as the space station passes over.
Leaving your radio on the ISS 2m downlink with an audio cable connected to a
PC which is running VoxRecorder will automatically record wav files when the
squelch opens.
Just listen or view whatever you missed while you were hard at work at your
convenience.

The tracking algorithms for satellites have been developed over the
years and AFAIK they are adequate, certainly for amateur use. The
orbital elements contain a drag factor (orbital decay) which compensates
the tracking for the gradual orbital decay.
IMHO updating elements every 10 days is adequate for most satellites.
If you use manual tracking the time interval between updates can be
increased. I tracked OSCAR-11 (UO-11) manually for many years, and
usually, only needed to change the Keplers about four times a year, when
the predicted time error exceeded more than a minute or so.
Satellites in very low orbits have a greater rate of decay, and it helps
to update the Keps frequently, especially those nearing the end of their
orbital life. The manned space stations have a high rate of orbital
decay. Their orbital height is corrected by firing their thrusters, so
frequent updating of Keps is needed.
Regarding solar max, this will increase the decay rate, but in most
cases this will be corrected by the increased drag factor in the Keps.

Three possible projects -
Firstly, when satellites decay and burn-up in the earth's atmosphere,
there is always an interest in predicting when this will happen, say a
month before. In the past we have had several so called 'Chicken Little'
competitions for the best prediction. I did a lot of work on this 20
years ago, but never finished the project. It was based on a
statistical analysis of how the drag factor varied with height, the
exosphere and solar flux. As a project you could reasearch any work on
this topic, or try to produce a procedure for predicting satellite
decay.
Secondly, you could investigate tracking errors caused by changes of
solar flux. The effect of these errors, and how often Keps should be
updated.
Lastly, there are at least two, possibly more different algorithms for
tracking calculations. You could explore the differences, between them
for amateur satellite aplications.
If you are interested, I may be able to help. Please e-mail me direct
g3cwv at amsat.org ( replace the ' at ' by (AT)).

A vox recorder will work, however a running SSTV problem will work much
better. Just make sure you save the images to disk. Most if not all SSTV
programs have an Auto Receive move and will save to disk.
Practice at home sending and receiving images between two radios on your radio
bench.
If you have HF you can try to RX on 14.230 SSB, that freq is usually busy with
HF sstv.
When you are all set, go to FM 145.800, Robot-36 and leave the rig on 24/7.

Hey Everyone,
This weekend, AO-51?s operations team is giving all of us who work the FM
satellites a chance to answer the question in my post's title to our own
satistaction.
Here, I?m reaching for a fresh set of Duracells! I?ll be running QRO on them
this weekend, though ? pumping all 300 milliwatts out of my VX-7R HT into the
new Elk log periodic antenna I?ve been running through the ringer for a week ?
with really good results.
I challenge all of you who will be working the ?QRP pair? on AO-51 this
weekend to see how low you can go with the RF out and work the satellite. As
many of you know, the Satellite Communications Achievement Award (No. 473)
that just got posted to the AMSAT Web site for N3TL was earned solely on the
basis of confirmed contacts I made while running 50 mW rf out of the VX-7R ?
on the same set of 2 AA Duracells. I?ll use the other alkaline-battery power
setting this weekend, which is 300 mW.
One of the elements of this very low power work I find most exciting is trying
to ?reach out? as far as I can. For me, it?s not the distance from N3TL in
EM84 to the other station I?m working on fractions of a watt that is
important. Rather, it?s the range from my location to the satellite at the
moment of contact. That tells an interesting story, I think.
Example ? During my Duracell Experiment, I worked Jim, KC9ELU, on AO-51 when
the satellite was at 8.6 degrees elevation to my west. I use Orbitron to keep
track of upcoming passes, and its simulation mode lets me go back, after a
pass, and check stats from contacts. When Jim and I worked, my 50 mW traveled
2,482.003 km (1,542.245 miles) to the satellite. Do the math ? that?s
49,640.06 km (30,844.9 miles) per watt. I don?t expect to get close to those
numbers at all on 300 mW this weekend, but I?m anxious to find out.
I will post my farthest to-the-satellite distance that resulted in a two-way
contact early next week. I hope others will do the same, including rf out and
distance to the satellite during the contact. Not only is this fun (for me, at
least), but it also provides a great test for our respective stations, letting
us know ?how low we can go? in, say, a true emergency and still complete
effective communications.
FYI ? I always err on the side of caution when posting numbers like those
above. That is, I always use the highest elevation/shortest range to my
location. Even a few seconds during a contact has the satellites moving ever
closer or ever farther from us, depending on which part of the passes our
contacts occur. I use the highest angle/shortest range because I know it was
no higher or no closer to me during the contact.
I hope to try some SSTV reception, but probably on the higher angle passes
here because I have no experience at all with SSTV. On the lower angle passes,
however, I hope to work many of you on the QRP pair while I?m wearing out
another set of Duracells ? and in between passes of AO-16 (more about that in
another post).
73 to all,

I?ve mentioned in posts to the BB this week that I would like to apply for a
separate Satellite Communications Achievement Award from AMSAT using only
confirmed contacts on AO-16 in this unique and, most likely, ?one off?
operating mode of V-FM up and U-DSB down. It?s a real hoot to work, as some of
you know ? and there?s no guarantee we?ll have AO-16 much longer. That?s been
reported in the just-arrived (July-August) issue of ?The AMSAT Journal? by
Drew, KO4MA. The first report on AO-16?s rebirth appeared in the March-April
issue of the Journal.
As I write this, I?m one state/Canadian province/DX country away from the 20
necessary to apply for the award, but I?d like to work as many as possible
before AO-16 goes silent again ? and maybe forever.
Here?s the list worked by N3TL so far in AO-16?s ?bent pipe? mode:
Venezuela
Ontario
California
Florida
Indiana
Iowa
Kentucky
Louisiana
Massachusetts
Michigan
Mississippi
New York
North Carolina
Ohio
Tennessee
Texas
Utah
Vermont
Virginia
Thanks to Clare, VE3NPC, who read an earlier post in which I referred to my
interest in trying for my own little AO-16 award. He made a pass later than
day and we had a great contact. Thanks again for that, Clare!
I?m thrilled to have made contacts with the stations that made the very fist
voice contact on AO-16 back in January (as reported in the earlier Journal
article mentioned above) ? N8MH and KO4MA. That?s pretty cool!
So, if you live somewhere not listed above and have the time and gear to make
a pass of AO-16 that includes north Georgia in the footprint, I?ll be
listening for you! As for the necessary gear, I?m routinely using a ?poor
man?s full duplex? station ? transmitting from my Yaesu VX-7R HT into an
eFactor omni antenna mounted on a photo tripod and receiving on a Yaesu FT-
817ND connected to my Elk log periodic. On passes to my east, I'll use my
"base" transmitter, a Yaesu FT-857D into the eFactor omni, with the RF out on
the 857D routinely set to 5 watts. I?m manually tuning for Doppler on the
receive side, and hand-holding the Elk to track the receive side manually.
It?s a little challenging, but a lot of fun!
FYI ? the frequency pair is 145.920/FM up (the same as AO-51?s ?normal? 2
meter uplink) and 437.026/DSB (+/- Doppler) down. Listen in upper sideband,
and start looking for AO-16 at about 437.036 at AOS, tuning down from there.
No matter where you live, you really ought to work some passes of AO-16 if you
can. There?s a historical significance to this current mode and the story
behind it that?s pretty special, I think, and worthy of our interest and
attention.
73 to all,

? I'm going to be demonstrating satellite operations to a group of six High
School students this afternoon. They're all working on their Tech Class
licenses and I'm trying to get them interested in satellite operations. We
even have the local newspaper's reporter lined up to watch, so their will be
some good public relations.
?? We'll be on the 2300 UTC AO-51 pass and would be appreciative if anyone who
could contact us. We're pretty far west so it'd be great if stations on the
west coast or our Canadian neighbors would give us a try. The call sign will
be our club call, AL7YK and grid is AP90ds. We'll be using our club's arrow
antenna with a IC 91AD HT.
?? Well also be on AO-7 on?most of Sunday's passes who anyone who'd like to
work our grid.
Thanks.?

Hello Joe & BB,
I am assuming you are being general about the 2300Z pass.
I will be changing the modes of AO-51 tonight (10 Oct) during my 23:20Z
pass here in the eastern US.
It looks like this pass comes over AK about 2335Z. I hope to complete the
change for both transponders and collect telemetry. Some of the commands
will be in the blind, so there is a chance that the total change over may
not be complete until the 0101Z pass 11 Oct over my QTH.
Also since this is a N - S pass for you, someone in Alaska would have to be
transmitting a SSTV signal using the 1.2 GHz uplink for you to receive that.
I will try to get the QRP transmitter working first, check the
uplink/downlink freqs below.
October 11 - October 12
SSTV Repeater, L/U (ROBOT 36 only, please be courteous!)
Uplink: 1268.700 Mhz FM
Downlink: 435.300 Mhz FM
QRP FM Repeater, V/U (10 watts and omni or handheld antennas only)
Uplink: 145.880 Mhz FM
Downlink: 435.150 Mhz FM
73,
Gould, WA4SXM
AO-51 Command Station
