I agree about jitter and possibly distortion, but it's not something I commonly do, and it's not noticeable when I do it! And as the gaps we're talking about are way more than would be seen in the empeg digital system, I doubt it'll be a problem.

Interestingly, it will keep an existing signal from further away than it will accept a new one - i.e. if I purposely break the beam with a piece of card or similar, it will not pick up again until I move the transmitter closer.
