Thanks Clint!

I just checked for a Java update and there was one. I updated and reinstalled SatScape and now all is well.

I will keep this info for future reference.

When SatScape works, it is wonderful. When it doesn't, the author really isn't into supporting it any longer ...

Hi all, Here's another short article that you may find useful.

As you may know by now, no computer program is 100% stable, its an
impossible task for a programmer to make it work all the time, the
best you can do is to do your best to make it work, and when it fails,
provide solutions to fix it.

So, with this in mind, here is one thing you can do that could fix
most problems you may encounter. From information I've received over
the years one thing that messes up from time to time is the settings
that satscape uses to allow you to customise satscape, Eg. your
favourite satellites, your latitude/longitude etc. So one sure-fire
way to fix problems with that is to do a kind of 'factory
reset' (assuming Satscape used to work when you first installed it).
Heres how to do this, the satscape settings are stored in one folder
on your hard drive, which is in a different location depending on what
operating system you have, so first locate this folder...
Windows 98 or XP : C:\Documents and settings\YOUR NAME\Satscape\
WIndows Vista or 7 : C:\Users\YOUR NAME\Satscape\
Mac/Linux : /Users/YOUR NAME/Satscape/
The most simple way is to rename the Satscape folder to 'Satscape-
backup' and then start up Satscape, it will see there is no satscape
folder, and so recreate all the default/factory settings again for you
and that should fix the problem. If it does not fix the problem,
simply rename it back so that you don't loose your settings!

... and ...

Heres another procedure which tends to fix java-related errors...

This is the same procedure for Windows XP, vista and Windows 7:
go to the windows control panel, double click on 'Java'
near the bottom-left theres a 'View..." button, click that, on the
window that opens, click 'satscape' in the list, then click the red
cross at the top of the window. Repeat this if you have another
'Satscape' in the list.

On the top-right where it says "Show : Applications" click the drop-
down list and change it to 'Resources'

if you see 'Satscape.jnlp' in that list, click that and click the red
cross.

This will clear out the java cache, forcing your PC to go get new
copies of the files.

Finally click this link : http://www.satscape.info/java/satscape/Satscape.jnlp
to install a fresh copy (this is the same link as the web site
download link)

Mac users: Spotlight > "Java preferences" will get you into the same
place mentioned above.

It's interesting that both KA3MTT have this issue and SO-50 is the only satellite I've made contacts through so far.

This is a lot of fun and has really rejuvenated my interest in the hobby. I used to think VHF was just for local communications! Ha!

Hi Clint, and thank you for your reply!

Yes, I have programmed the radio with those frequencies. I don't know if it's possibly an issue with the terrain in this area? That may be a dumb question or idea, but the fact that KC8HQS and myself have the SAME issue is odd. We live within 20 miles of each other, and it just seems kind of odd.

We are both able to follow the pass for about 85-90% on the mid-pass freq.

Not a problem for us, just trying to make some sense of it, that's all.

Re: ARISSAT1 TELEMENTRY

Siegfried Jackstien
 

You will need more gain on the antenna i think
I have a stacked vertical (x510) ... with that I am just at the decode
margin ... and that with a sensitive sdr radio (funcubedongle)
I think with a small beam you would have better luck
Or you have to have a very close pass ... but then your j-pole will have a
receiving hole upwards ...
I made a second antenna for high passes (qfh) ... on high passes the qfh is
better (and on some passes were the sat has more horizontal then vertical
polarization) ...
If you have a strong cw signal and you also can hear the bpsk signal very
good ... then the decoding should work ...
If you have your antenna system so that you can receive and decode
"something" then I would recommend a cat connection to pc and qrg tracking

For decoding lots of frames in a pass the cw note has to be rocksteady or
make only very slight and slowly movements ... so compensating Doppler is a
"must have" to be able to decode 30-40 frames in a pass
But even compensating the Doppler by hand should give you some frames if you
receive the signal "decode-able"

I am using a IC746Pro and an Arrow J-pole mounted on the roof. I have been
able to receive the SSTV pictures but cannot seem to get the Telementry
signal. I have the program all set up and I tune to 145.919 and listen for
the CW signal and then try to tune it so that I get it on the line -
Yellow= but nothing seems to work. I have the receiver set to USB. What
else do I need to do?

Re: ARISSAT1 TELEMENTRY

K6LCS <clintbrad4d@...>
 

Isn't that a 100mW transmission? And with a hardly-any-gain-at-all J-Pole .... Well, I wouldn't try that combination.

Here's the stuff from the ARISSat-1 page on receiving the telemetry - you probably already know this ...

How To Receive the ARISSat-1/KEDR BPSK-1000 Telemetry

The BPSK transmission from ARISSat-1/KEDR will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will transmit satellite telemetry and data from the Kursk experiment.

You'll need to take a few steps to get your station set up to receive, decode, and display the BPSK-1000 telemetry data:

You need a 2 meter SSB receiver.

An audio patch cable between your receiver and computer's soundcard is required.

Download the ARISSatTLM ground station soundcard demodulator and display software. Windows and Mac versions are available.

http://www.arissattlm.org/

Follow the instructions in the ARISSatTLM Software Quick Start Guide to install the software.

http://www.amsat.org/amsat-new/images/fck_images/ARISSatTLM-QuickStart%281%29.pdf

The ARISSatTLM software can decode BPSK signals in two modes:

Playback and decode a recorded file (even if you do not have a 2 meter SSB receiver you can experiment with the software and test file to learn about telemetry decoding and display!)
Live, off-the-air capture


Playback and Decode a Recorded File

ARISSatTLM requires the recorded data to be in the WAV format. Compression formats such as MP3 are not suitable and will not decode and display correctly. Although .WAV files are notably large, usually several megabytes, they capture all of the bits of the signal. Compressed file formats sound OK to the human ear but save file space by eliminating bits from the recorded stream. You need to capture and record as many of the downlink bits as possible. An occasional noise burst or momentary fade is handled by the Forward Error Correction capability of the ARISSatTLM software.


Download the BPSK Test File

A link to a BPSK test file suitable for operation with the current release of ARISSatTLM software will be released soon to http://www.arissattlm.org.

NOTE: Some earlier BPSK test recordings that are on the internet will not work with the currently released software because they were created with earlier versions of the satellite's onboard software (the satellite software and ARISSatTLM are a "matched pair").

Start the ARISSatTLM program on your computer.

Click the start button in the lower left of the Tuning Indicator window.

In the ARISSatTLM Version 0.50 Window select: File --> Open WAVE file. Select the ARISSatTLM test file you previously downloaded.

The Tuning Indicator window will show the "CW Bump" at proper location (note the "Put CW signal here" indicator).

The Morse Code Decoder will decode and stream the CW message.

The ARISSatTLM Telemetry as Text window will decode and display data.

The ARISSatTLM window will display the received data as received.

The display will stop when the end of file is reached.


Live Off The Air Telemetry Capture and Display

The ARISSat-1 BPSK-1000 downlink is transmitted in SSB mode on 145.920 MHz. When the CW2 beacon on 145.919 MHz is active this indicates that the BPSK-1000 format is being transmitted. If the CW1 beacon on 145.939 MHz is active this indicates the backup of BPSK-400 format is being transmitted.

Transmitting at 100 mW, both BPSK rates include Forward Error Correction (FEC) and it is expected that modest quarter-wave antennas with low-loss coaxial cable will provide sufficient signal strength for decoding and display by the ARISSatTLM software.

BPSK-1000 sounds like a "shusssch" with a higher pitch than the 400 bps growl. It is difficult to tune by ear. The BPSK beacon is centered 1 kHz above the CW2 beacon so that the CW beacon sits in the lower spectral null of the BPSK signal, i.e., in a narrow spot where there's no BPSK signal power.

If you put your receiver in USB mode and tune the CW beacon so it comes out at an audio frequency of 500 Hz, this will automatically center the BPSK signal in a conventional SSB filter extending from 300-2700 Hz. The Tuning Indicator window helps you tune the signal correctly.

Follow the recommendations in the ARISSatTLM Quick Start Guide for tuning and decoding the BPSK telemetry data. Once you are tuned in correctly (and adjust for doppler shift) you will be able to decode the BPSK-1000 signal. You will also be able to copy the CW2 beacon text in the Morse Code Decoder window.

AMSAT needs your telemetry from ARISSat-1/KEDR. Since there are no "Whole Orbit Data" storage mechanisms onboard ARISSat-1/KEDR, your submissions are the only way for AMSAT to collect the spacecraft telemetry and KURSK experiment results.

The telemetry may be recorded using the FunCube dongle or SDR-IQ receivers. After decoding the recorded file ARISSat-1/KEDR and Kursk telemetry CSV files (in the ARISSatTLM folder) can be sent as an e-mail attachment to telemetry@arissattlm.org
If you are running ARISSatTLM and receiving the signal "live" from ARISSat-1/KEDR, please enable the telemetry forwarding option.

I have an odd (maybe dumb) question about working SO-50. Myself and a friend of mine have both noticed that we can't seem to work SO-50 as well if we are compensating for doppler shift.

We are able to work it just fine if we are on the primary downlink frequency, but not the shift freqs. Any others have this issue?
