I. If you want to test the SatPC32 programs you can download the present German or English version 12.10. The program will be installed as Demo version. The only restricition of the Demo: The user's QTH coordinates can not be stored for the main program SatPC32.Exe, but have to be entered at every program start.
Further, the previous program versions 12.9 can still be downloaded (sect. II an VII below).
Vers. 12.10, Release September 2023?

Scope for the IC-9700
The full versions can be activated by entering a registration code. The code can be obtained from
AMSAT- DL (European users),
AMSAT-UK (users in Great Britain) or
AMSAT-NA (North American users).
The files themthelves
contain detailed information on how to purchase the code..
The included programs SatPC32ISS, Wisat32, WinAOS, WinListen, SuM and SuMListen (see page 'Software') are full versions.
IMPORTANT: READ SECTION III (INSTALLATION) BELOW FIRST BEFORE ATTEMPTING TO INSTALL THE FOLLOWING DEMO PROGRAM VERSION AFTER DOWNLOADING!
SatPC32 Demo V. 12.10, 46 MB, released September, 2023
Version 12.10 corresponds to previous version 12.9, but supports the new Keplerian data formats
CSV, KVN and XML in addition to the TLE Kepler data files (TLE = Two Line Elements). Files in these formats can be found on the Celestrak
website. The SatPC32 auxilirary file Celestrak.SQF provided with this release contains links to the Kepler files
"amateur.csv", "amateur.kvn" and "amateur.xml".
Note: If you restored your old data files with DataBackup after installation, Celestrak.SQF will no longer contain these links. To restore them, add the following lines to Celestrak.SQF (without the leading and trailing quotes):
You can start and edit Celestrak.SQF with the SatPC32 menu "?" > "Auxiliary
Look also for possible patch files (sect. VI below)!
To install SatPC32
on your PC proceed as follows:
1. Create a new folder on your HD (using the Windows File Explorer or another file manager) and name it (i.e.) SatSetup.
2. Download the appropriate program version using the links above.
3. Click on the
'Download' button of your browser (usually a blue down arrow).
Windows will display the name of the downloaded ZIP file.
Double click.on the file name. WinZip will now display
the content of the ZIP
Important: Don't try to run the setup program in thr WinZip window! You will get the message during installation that you need administrator rights, even if you are the administrator.
Click on 'Extract > On My PC' instead. and in the window that opens navigate to the folder you created and extract the files.
4. If this is the first installation of SatPC32 RIGHT click on *setup' and from the list that opens choose 'Run as Administrator'. Then follow the suggestions of the setup program.
5. Updating of older
The new program version can be installed into the same program folder that contains the older program version. Unfortunately, the older installation has to be removed first, however. Otherwise, the Installshield setup program of SatPC32 V.12.8d will refuse to install the update Your personal settings therefore will be lost. The program 'DataBackup.Exe' allows you to easily save your settings via mouse click and then to restore them after the installation of V.12.8d is finished. The program 'DataBackup.Exe' can be started from menu 'Programs' of your previous version or in the SatSetup folder (see above)..
After V. 12.8d has been installed run DataBackup again either from the new SatPC32 menu 'Programs'.or in the SatSetup folder and restore your settings.

Vers. 12.8 (full version).
DDESat32 is an interface program to be used with Wisp32. The program is in German but easy to understand by everyone (see the description and screenshots on the page 'Software').
To install the program
unzip the downloaded file into an empty folder on your HD. Start the
setup program in that folder and follow the instructions.
For detailed information read the DDESat32 Manual (English).
Download DDESat32 for use with SatPC32 V. 12.8 and later.
If you are using SatPC32 12.4 ... 12.7 download the older version DDESat32_12.4.
7. AOS.Exe (DOS-version): No longer available.
8. SuM programs
The SatPC32 V. 12.8d setup program installs these programs automatically.
9. ServerSDX update: Now installed by the setup program
Beginning with program version 12.8b the setup program installs TimeSync automatically. It can be started from the SatPC32 menu "Programs".
Satellite operation requires a highly accurate system time. TimeSync synchronizes the PC's system clock with one of the internet time servers. This way you can ensure that the PC's system time is accurate.
If you run an older SatPC32 progam version you can download TimeSync with the link below. Extract the TimeSync setup program from the downloaded ZIP file and save it somewhere on your HD. Start it by double clicking on the file name "TimeSyncSetup.Exe" and follow the instructions.
IMPORTANT: Under Windows Vista and Windows 7 the setup program must be started with the option "Run as Administrator". To do so right click on the program name and in the list that opens choose that option.
The setup program generates an icon (shortcut) on the desktop. To start TimeSync double click on the icon. For further instructions click on the "Help" button in the TimeSync program window. .
11. Buffer interfaces
Buffer interface for Labjack U12
interface for Labjack U3
For rotor control with the Labjack U12 and U3 an interface is required that buffers the output terminals of the U12 and U3 vs. the rotor control box. Unfortunately the readymade 'Piggyback' from NLSA is no longer available. With the 2 links above you can download the schematic diagrams of this homemade interface which also show how to connect it to the U12 and U3. The interface can easily be duplicated, the only component is a ULN2003AN. I don't have a PC board, however. I mounted the chip and the 8-pin DIN connector on a small piece of conductor board, see picture.
Buffer interface for antenna switch
If you want to use the FUNCube Dongle Pro + (or another SDR) as satellite receiver for U/V satellites (AO-07, AO-85) and V/U satellites (FO-29, SO-50) as well you need to switch the VHF/UHF antennas. That can be done via a Coaxial Transfer Switch. The voltage at the DTR pin of the Radio 2 COM port can (optionally, see menu "Options") be used to control this switch. The voltage of the DTR pin of the Radio 2 COM port then changes when the user switches between U/V and V/U satellites (U/V: low, V/U: high).
The solution requires a buffer interface between the COM port and the antenna switch relais, of course.

Interface for antenna switch
How to add data for new satellites
The data files that come with SatPC32 contain data for many important radio amateur satellites. Data for other satellites must be added manually to the existing data files. For detailed hints see the "Tutorial" by Wayne Estes, W9AE. It can be displayed from the FAQs file, sect. 1a.
With the link below you can download data of the lately launched SO-67 and HO-68. The data can be added to the existing data files Doppler.SQF, SubTone.SQF and AmsatNames.txt.
