Could you tell me what is the difference? Is CPFSK just the assurance that the phase of the signal will not change when a switch from the mark to space frequency (or vise-versa) occurs, or is there more to it?

Will a standard fsk receiver work with a cpfsk xmitter? And what about the opposite, will a cpfsk reciever correctly receive a fsk transmission?

Thanks,
Terry
