If spacetime is quantised, does that have any measurable effect on signals?

How can everything be isotropic?

If lightspeed is one planck length per planck time, are all other speeds just introducing a delay after every N ticks? Seems like that would create noticeable jitter at high speeds.

Planck lengths and planck time is simply the smallest quantities of time and space we can measure, they do not reflect a fundamental feature of reality. If the smallest thing you could measure was an inch, you wouldn’t go around being like: “It’s so weird how the world is perfectly quantized into one-inch increments!” 

Damn.

If it was a practical limitation I wouldn’t.

But afaik planck lengths and planck time are the smallest quantities we can measure in principle, i.e. no matter how advanced technology will get they’re just hard limits we’ll never be able to cross. So I don’t think those things are really the same at all.
