PC board real estate is expensive, microcode space isn't. Given the component density already in the 396 I don't think it is quite so easy to cram one more chip in there. If Uniden really wanted D-STAR then they'd likely just license the codec algorithms and code that into the microprocessor just like all the other digital codecs that are currently processed.
