modulation

[00SHAZ00]

im in the search menu of a ddigital plus, there is an option called 'modulation' with setings of 16qam, 32qam, 64 qam etc, what do these do and what do they mean?

Thanks

Not sure exactly what it means, maybe this will help.

But usually 64-QAM does the trick.

thanks for the reply m8, your right about the 64Qam part as this was the original setting, i was just wondering what changing it would do, just curious.
