Purchased some low cost pc's to do some satellite radio work and had a couple left over from my learning experiences. Decided to set one up for Sentinel for my SDS 100 and 200. !st pc has an AMD processor. Got the Sentinel installed via the link provided by another member in a different thread. Installed ok but no matter what Sentinel won't show the card installed in the scanner under any circumstance. Put the card in a card reader and Sentinel can see it on the AMD. Card back in the scanner is a no go. Tried all variations of reformatting and starting from scratch. Tried ll kinds of Windows settings. No go. Then I installed Sentinel into an Intel processor stick pc and it works great. It sees the sd card installed in the radio and it works great. I'm only bringing this up because in my setting radios up for Inmarsat I've discovered that AMD processors don't work too well with programs written in C++. For instance Jaero won't run on AMD processors. At least not the one I have. Can be very frustrating. Don't know if the sd card problem is an AMD thing or not but this has been my experience. Both of these pc's are running Windows 10 pro. Just thought I'd pass it on in case someone knows a magic trick to make it work with the AMD processor. I've read and done all the things mentioned in the other threads. Thanks for taking the time to read this.
