Tone() Function => Video Transmitter

Hi Gang

I'm seeking some guidance. I've been playing with the tone() function but I'd like to extend on the examples (see link) where a 100ohm resistor and 8ohm speaker are used. I'd like to play the tone through a video transmitter (see link). I don't believe I can substitute the resistor and speaker and simply connect between ground and audio in (maybe I can)? How do I go about this? Any advice/links would be greatly appreciated.

Cheers
