Steve (and others),


I wrote directly to Erich, the SatPC32 author, about this problem. FYI, below is his very nice reply:

Mark,
Happy New Year!
I don't remember my comment in 2006. You are right - since the problem is specific to only one satellite it doesn't make sense to completely re-install the program, I think.
Perhaps you proceed step-by-step: 
Run SatPC32 with configuration #1 (menu "Setup") and group "Standard". Choose  nasa.all as Keps file. Leave Doppler.SQF and SubTone.SQF and (eventually) Prior.SQF unchanged, that means WITHOUT entries for BY70-1. Make sure that there is at least one ident letter free for a new satellite. 

Then open menu "Satellites" and add BY70-1 from the "Available" list to the "Selected" list and click the  "OK" button. A new ident letter should appear. Click on it to switch to BY70-1. Does that cause already the io 105 error?

SatPC32 saves the "Selected" list of group "Standard"  in the text file "Standard.Sat" in the SatPC32 DATA folder (path can be seen in footline of menu "Satellites" ). Is there something unusual with that file? At its end it should show:
BY70-1
-
The minus char below the name indicates that the option "Show On/Off" (menu "Satellites") is unchecked (no asterix in front of the satellite name). 
Attention: Make first hidden files and folders visible using the Windows File Explorer, because the folder "AppData" in the path is hidden by default. 
73s, Erich, DK1TB

Mark,

I also get the “E/A-Fehler 105.” error message when I add BY70-1 to a
satellite group in SatPC32.  Other people don’t have the problem.

The error message (in German) means I/O Error 105 in the Delphi
programming environment, which I believe is an error writing to a file.

What I can’t yet answer is how to fix the problem.  We may have a file
permissions problem.

Anybody have a solution or know where to look?

73, Steve N9IP
