Based on what I see, the poster claims 12.8d is available for download from the link supplied. However that does not appear to be the case. In review of the SatPC32 site, Only a demo version is available and there's no "Update(r)" version that can be applied to current versions that I can find. What is really the case? Is this going to be available as an update for current registered users of SatPC32 12.8c, or do we have to pay for a full blown program via the AMSAT store? From what I see the AMSAT store does not provide a update link, only to purchase a new program entirely. I don't see any indication that the AMSAT store is providing the 12.8d version updater. As a matter of fact, it does not even say what version of SatPC32 is being offered. Steve NS3L
