I'm a little confused about simulcast systems and CQPSK modulation. I live in western Ottawa County in Ohio, which is about 20 miles south of Toledo. I can pick up the Monroe County system but it cuts in and out quite a bit. But I am able to pick up the Flat Rock tower from the MPSCS with almost perfect reception. So my question is what is the advantage to using the CQPSK modulation on a simulcast system? The Ohio MARCS system uses a simulcast system in Franklin County without CQPSK and so does Delaware county in Ohio and the reception is much better. And what does CQPSK stand for?
