Hi,

SatPC32 stores the configuration setting. So it starts with the configuration that you used last When you start a second instance and change the settings the second instance will work with these settings. But you can't save the two different settings. At the next program start both instances start with the same (last) configuration and therefore with equal settings.

But there is a way to run two instances of SatPC32 with two completely different configurations at the same time inclusive rotor and CAT control and storing of all settings. Of course, this only makes sense if you use 2 independent rotor / antenna systems and multiple radios. EACH instance requires either a satellite transceiver or two separate non-satellite radios, one for RX (Radio 1) and one for TX (Radio 2) and the necessary ports etc.

To run two instances you need a 2nd SatPC32.exe file in the SatPC32 program folder. The name must be different of course, e.g. SatPC32_2.exe.

The 2nd program file must be permanently set to a specific configuration

• say configuration 4 - Â regardless of the configuration chosen in menu

Setup > Configuration. So, a modified file is required (the modification requires only 2 lines of code). Some years agao I have uploaded a file SatPC32_2.exe for a friend of mine. It works fix with configuration 4: http://www.dk1tb.de/SatPC32_2.exewww.dk1tb.de/SatPC32_2.exe

For the 1st SatPC32.exe you can choose Configurations 1 - 3 with different settings. . (For CAT control of the IC-9700 this file should be used because the other one is some years old.)

To avoid hardware conflicts rotor and CAT control are disabled (default) with the 2nd file, but the functions can be enabled (SatPC32 menu ? > Auxiliary Files > DivOptions.SQF).

Of course, everyone is solely responsible for avoiding hardware conflicts.

Hi Erich, Thank you so much for the help my friend.

Is there also a setting to command Satpc32ISS the configuration to use at program start when neither SatPC32.exe or SatPC32_2.exe are running?
