The schematics and oscilloscope screenshots should be appended to your post, not stored on a filesharing server, review forum rules.
The information is also incomplete, I don't see a filter circuit or connected load, if any. The modulation scheme isn't completely clear, you should clarify relation of screenshots to signals.
