I think this comes down to personal preference. I know a lot of folks who will argue that one or the other is "better" but they both do what they are supposed to do. Some say there are a lot of falsing issues with PL and that DPL doesn't false. In actual use, I have heard both false. Some say there are interference problems with certain tones. This can be true in some situations. DPL will give you more choices since there are more DPL codes than PL tones. As far as I know, any modern radio designed originally for 900 MHz commercial use will do either well. I personally prefer PL because there are more after market devices for that format and it is easier to implement in some situations such as with phase modulated exciters. But it is still just my personal preference. Your Maxtrac should handle either format.
