Sorry, I cannot answer that question. My reference was more toward the replacement of an existing linear supply or new installations such as GMRS or Amateur Radio systems - repeater or otherwise. Whether or not their rule applies to newer Motorola or other commercial radio manufacturers - I'm not certain.
I am told that Motorola offers alternative powering methods to systems that normally come with switching supplies. I'm not totally sure why... possibly there are companies that aren't totally sold on "switcher" technology? Unfortunately, like with so many things, price dictates quality. If you buy a JAN crystal, be prepared to have it drift all over the place. If you buy a cheap switcher, be prepared to have it throw garbage out all over the place. While the better switchers like Samlex and DuraComm are good performers, many of us will buy something cheap. With education, more of us will buy the better product, like International Crystals with temperature compensation performed by them.
