Remember their is also NXDN you could do and the Kenwood Radios can do NXDN and P25 so that would give you the interops you need plus still save you some mega $$ as well.
You have to be very careful with this statement as many can draw confusion between the Kenwood NX lineup and the EFJ Viking lineup. The reason being, the only difference between a NX-5000 mobile and a Viking mobile is the firmware and the only difference between a NX-5000 portable and the Viking VP5000/6000 portable is again the firmware however you can't pick and choose. If you go with Viking products you are limited to P25 and analog. If you go with NX-5000's you get NXDN and P25, P25 and DMR or NXDN and DMR but some of the P25 trunking functions are as refined.
That being said, it has been hinted that here in the next year we should see multiband radios from Tait, BK Technologies and Harris with some form of DMR functionality. I purposely left one vendor out...see my signature as to why.
