Did you follow my instructions to set the local oscillator? What did you find?

To facilitate injecting video directly you will need to build a 75 ohm interface. It could be connected to the grid of the first video input stage. Then you could inject audio to the volume control. It will take a bit of fiddling as you have to ensure the video polarity is correct.

It appears you were very close connecting by the antenna. What happened?
