- Thanks for the reply. Good thought about the DCS and DPL modulation and direct FM. I have a couple of the Delta Crystal units but tired of buying crystals. Since the Phoenix does dpl I may get lucky there. I have a friend that has an application that best used true FM so I am trying to hook him up with a radio. I need to look at the diagrams more closely and see where they inject both the audio and PL.
