Gang --
I seem to remember there is a configuration file somewhere for SatPC32
which tells the program to run an ancillary program before SatPC32
starts up. I have one such ancillary script, but now I can't find the
setting where I can tell SatPC32 to start it. Incidentally, I'm not
speaking of the standard 'drivers' for rotors, like SDX.
One solution, of course, is to use a macro or bat file to launch
SatPC32 and my custom script, but, as I say, I have some recollection
of SatPC32 doing this itself. Perhaps I'm just so used to it
fulfilling my every wish :-)

Your attitude and enthusiasm continue to amaze me, Patrick - Great work!
I demo'd AO-51 yesterday morning before a club meeting of 63 folks.
From Tarzana, CA we talked to Tennessee, West Texas, and, lo and
behold, Athens, Georgia's own N3TL came through. It was a 4.1 degree
of elevation pass for him. Let me repeat that, in case you thought
there was a typo: FOUR POINT ONE DEGREES OF ELEVATION for Tim in
Georgia. But he was cheating: he was using a full five Watts output on
his Yaesu FT-60. I refuse to use high power during my demos...(grin)
And so it goes....

The drawback is that would kill Phase-IV stone dead and AMSAT-NA won't get
another opportunity like that.
There is unfortunately no existing big pot of money in the Amateur Satellite
community to fund satellites/launches. Clearly funds have to be raised from
collaboration with non-Amateur organisations wherever possible.
Just building an HEO satellite can cost half a million+ dollars. In commercial
satellite terms that's really cheap but it's still a struggle for Amateurs to
raise particlarly when you consider there may be currently little more than a
thousand Active satellite operators world-wide. Off the top of my head I can
only think of three AMSAT groups that have more than 100 members, AMSAT-NA,
AMSAT-UK and AMSAT-DL. (I really would love to be proved wrong on that).
The half million+ dollars is just to to build the sat, as has been mentioned
many times there's the $4+ million for a commercial launch as well.
As an illustration of the funding issues take the 1.2 /2.4 GHz Amateur
Antennas that where installed on the Columbus Module of the ISS. Eight months
after launch Amateurs still haven't managed to raise the money to pay for it,
they are still 22,567 Euros short, see http://www.ariss-eu.org/donations.htm
AMSAT-DL has been trying to raise money for P3E with it's pixel page, see
Get into Orbit with AMSAT-DL's P3E-Satellite
http://www.p3e-satellite.org/index.pl?lang=en_EN
>From looking at it you can get a rough idea of how much they've raised so far
and how much further there is to go.
AMSAT-ZL are trying to raise NZ$12,000, that's 8,454 U.S. dollars, for KiwiSAT
to complete the design and construction of the basic unit to flight ready
status. I hope they are eventually successfull in managing to raise from
Amateurs the $8K dollars they require for that stage of the project, see
http://www.kiwisat.org.nz/funding.html
I think we need as many different AMSAT groups as possible to press ahead with
their own developments and tap whatever local funding sources may be
available in their country.
The more satellites that are built the greater the probability that one or
more will successfully make it into orbit. We have to remember even 'reliable'
launchers fail sometimes.

I'm having trouble receiving DO-64.
It seems to be strongest at the beginning of the pass and then gets weaker.
What is the polarization of the up link and down link?
I'm using a KLM 14 el LHCP for down link and 11 turn helix RHCP for up link.
When conditions are good (no local QRM) , I can hear AO7, VO-5, and FO-29
easily AOS/LOS even thought I have ground clutter up to about 20 degrees with
my antennas 8 ft. off the ground.
I would be interested in how strong others are receiving DO-64 and at what
signal strengths.
By the way, the beacon sounds stronger than the transponder signals.
Tnx,

Hi Jeffrey,
you wrote:
> hi folks, can anyone exlpain a little of this copy to us?
Since I haven't seen anyone else reply (yet) I'll
try to answer this. Remember: you asked. :-)
These are all packets sent from the onboard computer
aboard AO-51. The PECHO-11 callsign is AO-51's
broadcast callsign and the packets from this callsign
(and PECHO-12) will contain data in the Pacsat Protocol
format. This is the protocol that the onboard BBS
uses to send and receive data in a way that time shares
the satellite with all of the groundstations. Your
computer needs to be running a program like WiSP in
order for your computer to talk to the satellite using
the Pacsat protocol. (I say "like WiSP" because there
are other program besides just WiSP that also speak
this protocol, but WiSP is probably the most popular.)
The TLMS and TLMI packets are telemetry packets that
contain information about the health and current status
of the spacecraft. The TLMI packet is sent as binary
data and you need a telemetry program like TlmEcho or
Sabins to decode the telemetry into meaningful values.
(Full disclosure: I wrote the Sabins telemetry program.
It's free if you want a copy and I don't make any money
from it.) If you received the 9600 baud signal with
a program like Willow, or if you saved the received
packets to a KISS file then Sabins can go back and show
you the decoded telemetry and what it means. Since the
data in the TLMI packets is binary you have to have saved
it as a KISS file, not as ASCII text, or you will lose
the binary data. If you use an Apple, then you need
MacEchoTelem.
> PECHO-11*>PBLIST <UI>: PB: Empty.

The queue is empty. Probably nobody is using the
BBS right now.
> PACBLS-8*>PACBLS-8 <UI>: PACBLS S Meter = 0

The S Meter reads zero right now (or at the moment
when the computer looked at the S meter).
> PACB-1*>TLMI-1 <UI>: [and some binary data]
>
A telemetry packet. The binary data you put in your
email didn't make it through the mailing list, but
this packet will tell you all about the voltages,
currents, and temperatures on each part of the
spacecraft. Everything from the solar panels to the
battery control regulators to the radios to the
torque rod... and so on. It will also tell you
what is turned on and what is turned off. You need
tlmEcho or Sabins or MacEchoTelem to decode this
information so that you can see what this packet is
saying about the spacecraft. (Ok, you *could* do all
of the polynomial calculations by hand, but it would
be very tedious.)
> PACB-1*>TLMS-1 <UI>: C0:0D C1:44 C2:76 C3:2F C4:04 C5:01
>
A simpler telemetry packet. The "C" numbers are channel
numbers and the hexadecimal number after the colon is a
bitmask that tells you about things like the BCR DAC chip,
the transmitters, the torque rod commands, receiver
channels selected, CTCSS tones, some stuff about S band,
and so on. For example, C2:76 tells you that
- The RS-232 power monitor is OFF.
- CTCSS TXA and TXB do not have valid tone(s).
- Receivers 1 2 and 3 have their receive frequencies
set to the main frequency.

Again, more of "nobody is using the BBS right now."

This is a byte counter. Your software can save this number
and then when you get the next STATUS packet the software
can look at the new number and get a count of the bytes
(of certain types) that were sent by the spacecraft between
the two packets. You can compare that count to the number
(of those types) of bytes you received and see just how
much of the satellite's transmitted data you missed or
received in error. This gives you an idea of how good your
reception of the satellite's signal was between those two
packets. This number (apparently) does not increase for the
bytes in telemetry packets.
>PACB-1*>LSTAT <UI>: I P:0x13A8 o:0 l:27208 f:27245, d:1 st:6 e:8b
>
Some lower level satellite status. For example, "d:1"
indicates that the AX.25 digipeater is enabled. If you
were to send a packet "VIA" AO-51, and if AO-51 heard it
without any errors, then AO-51 would retransmit your
packet on the downlink for everyone else to receive it.
For more information on the PASCAT protocols, see
http://www.amsat.org/amsat/sats/nk6k/msatpro.html
(Note: there are some addendums to those documents.)
For more information specifically on AO-51, I recommend
"AO-51 Development, Operation and Specifications" by Gould
Smith. You should be able to get a copy if you call
Martha at AMSAT or via the AMSAT store at
http://www.amsat-na.com/store/item.php?id=100047
And if you're really really interested in this sort of
stuff, you can get a copy of the "Digital Disk" which
includes WiSP. (Full disclosure again: I wrote a few
things on the Digital Disk, but again, I don't make
money from it.)
Good luck, and see you on the birds.

Subject: [amsat-bb] Yaesu G-5400B calibration
I have a Yaesu G5400B that came in in a box all disassembled.
I put the azimuth unit together and it is working ok, But I am unable to
calibrate it. The direction indicator works and follows with the rotor
but is off.
Is there a correct way to position the potentiometer when re assembling?
I have followed the manual as to calibration set up.
Any ideas?
Thanks de John K?CQW
Hi John, K0CQW
Calibrate the mutual position of the potentiometer and the gear box of
the rotator is very easy.
The azimuth unit of a G-5400B or G-5600B make a rotation of 360?.
Rotate the unit between the limit switches and stop it when the rotator
reaches the midle position i.e. 180 ? from one limit switch and 180? from
the other limit switch and put a mark outside of it's bell as a reference
point.
The potentiometer is a linear 500 ohm potentiometer.
Without to rotate the motor from the above reference point desengage the
potentiometer from the gear box.
Using an ohmeter rotate the potentiometer by hand until you measure
250 ohm between the center wiper and each end of the potentiometer and try
to be the better balanced as possible.
Without to rotare the motor from the reference point and without to rotate
the potentiometer from the center point reingage the potentiometer into the
gear box.
The mechanical calibration between the potentiometer and the rotator gear
box is now completed.
Connect the azimuth rotator to terminals A1-A2-A3 of the control box
Switch ON the control box.
The voltage between A1 and A3 (the ground) must be about 6 volt DC
While rotating the motor fully CCW the voltage between A2 and A3
must became 0 volt and rotating fully CW the voltage must rise to
about 6 volt DC
On the rear of the control box and looking from left to right there are four
potentiometers in the order they are VR1- VR3 for cal of the azimuth and
VR4-VR2 for cal of the elevation.
With the azimuth rotator fully CW adjust VR1 until the pointer of the
azimuthal instrument read exacly full scale.
On the bak of control box there is an 8 pin socket for connection to the
interface of a PC
>From the outside view and rotating clockwise the pin are 6-1-4-2-5-3-7 with
pin 8 in the center.
Connect a DC voltmeter between pin 6 and 8 or to the ground and with the
azimuth rotator fully CW adjust VR3 to get exactly 5 volt DC
The calibration for the elevation unit follows the same criteria and
procedure.
have fun and

"AMSAT-NA won't get another opportunity like that."
And your point is?? At least we would have ONE working HEO in my lifetime.

Hi all!
After my success with FO-29 yesterday, I decided I would try
that satellite again and also try VO-52. Although I was not
successful with my second attempt on FO-29, I was successful
in making my first 2 QSOs on VO-52.
VO-52 had a very nice high pass, with maximum elevation of 82
degrees, at 1734-1747 UTC this morning. I was ready for that
with my two FT-817ND transceivers and Arrow Antennas handheld
2m/70cm Yagi. Only 5W, and I would adjust my transmit frequency
with the pinky on my hand with the microphone to keep on/around
my receive frequency. I set up shop around 145.910 MHz USB, and
started calling on there. Glenn AA5PK in Texas came back to me
at 1740 UTC, and we had a nice chat. After that, Tom N6NUG
found me at 1744 UTC near the end of the pass for another quick
chat. I've worked both of them on the FM satellites in the past,
and it was nice to get them on VO-52. Thanks Glenn and Tom!
I then planned to make one more attempt on FO-29 before returning
to Phoenix this afternoon. I found a nice high (maximum elevation
75 degrees) pass at 1835-1851 UTC. I could hear the downlink about
a minute or so into the pass, and could hear myself through FO-29
shortly after that. Around the halfway point of the pass, I lost
the downlink. I was not able to hear it for the remainder of the
pass.
My radios checked out OK, so now I need to take a look at my Yagi
and coax. I had a coax issue crop up a few months ago, so that
could be the problem. I have not read anything that would indicate
a new problem on FO-29, and I'm hoping there are no problems with
that satellite. I know I need to get a tripod for the Yagi, to
free up a hand during the pass, and get more practice with my two-
radio setup with an eye to adding computer control for both 817s
in the future.
I will put Delfi (DO-64) in my tracking program, and add it as a
favorite on my account at www.space-track.org, so I can try that
one out as well. I will also try AO-7 again, and maybe even go
back to my AOR handheld receiver in place of the second 817, to
see if I can make that work.
73!
