Mike, I had briefly talked to you about my Vara FM gateway project and just to let you know that my Windows 10 ISO install on the Rpi4 did not turn out well. The Rpi4 will boot but crashes soon after. I suspect it's a lack of memory (ROM) issue but will have to investigate. I have a Windows 11 mini-PC ordered for the time being but will update you as I get everything configured.
