[QUOTE="fsphil, post: 1014791, member: 410643"] It's here: [URL="https://gist.github.com/fsphil/3410e35e0b36b6dd580c6439a9aab415"]d-mac-tx.grc · GitHub[/URL] It just replays the frames I captured from the test generator. I've confirmed that the generator is D2-MAC rather than D-MAC. It can do D-MAC but it needs different firmware, which I doubt is easy to get these days :) I've written some code to generate my own D-MAC-ish signal, seeing what the minimum this Philips receiver needs to get a good picture. With just the frame and line sync patterns I can get it to lock but only ever for a brief moment before the image starts wandering again. And I thought this would be easy :) [/QUOTE]
