Jack,
Depends on what you mean by "loaded into SATPC32." As far as the keps are concerned, preliminary keps will probably appear here around the time of launch, and then in the tle-new download file initially. They will at first be with some sort of obscure object name, which will eventually get an Oscar number. You will then select it in the Satellites window.
As for the Doppler tracking, you will need to add that to the DOPPLER.SQF file as another poster has explained. Based on the posted frequencies, I have added the following to my file:
SumbandilaSat,435350,145880,FM,FM,NOR,0,0 SumbandilaSat,435300,0,FM,,NOR,0,0
The first will be the voice repeater and parrot, and the second the voice beacon. Note that to use the Doppler tracking, the name will need to match the common name in the keps list.
When they release the needed tones to select the repeater or parrot, you will need to go into the SUBTONE.SQF file and add them in. Docs in the file.
There really isn't any other way to switch between the two versions of SATPC32 without shutting down the first and then starting the second. The compete for the same resources, including the CAT and tracking functions.
