[Coco] Coco 1/2 RF faint?

[Jeremy Michea]

When you turn on your coco you get the green screen with the black letters, no matter which coco you’re using. I notice on my RF units (Coco 1’s and 2’s) that the black lettering is fainter and harder to read than when using a coco 3 hooked up to composite where the lettering is dark and sharp. I was wondering if this is just an issue of the inferior RF  signal versus the composite or is something else amiss here?
