Well,I can relate my experience with setting up and running a simulcast FM paging system,basically,they suck! Sure,you can spend thousands on a GPS based phase locked high stability oscillator and many more thousands on audio delay modules,but when you get out in the overlap areas,you get anything but a clean signal. It was so bad,we had the manufacturers send their engineers in and after their best efforts,it was horrible sounding. Music quality? Not a chance! Voice was barely adequate! The signals bounced and tumbled off of everything,twisting the audio terribly! We switched to a multi-channel zoned system and forgot all about simulcasting forever. The next best thing is to minimize the overlap with your radiation pattern. Like putting them on opposite sides of big buildings with some separation in between. Or what we did in the 60’s,alternated between two frequencies in an in-line fasion. You could be assured of a good signal on one or the other and no worries about sync of the audio or carrier.
