I'd say Motorola abandoned the rail industry, you don't see any rail products made by Motorola. Whether it was they didn't want to pay for NXDN/IDAS format or didn't get their way with P-25 the results the same, and the customer rules. They could have paid the small fee, it's not on the scale of P-25, but chose to leave the RR market since they couldn't control it. They could of even kept the Astro Spectra in the line or built an analog radio without NXDN/IDAS, as most RR's are not anytime soon going to digital. As far as only one channel programmed in a RR radio that's BS, all RR radios come with the basic 99 channel plan now in Narrow Band or the expanded plan if digital. The only exception is if they are on a closed RR with no other agencies operating on it or if they don't travel outside their own territory.
We contacted Mother M for a bid of over analog 100 base stations and they declined, then complained after the bid was awarded to Harris, not Kenwood or Icom. Motorola still thinks it's the 70's when they controlled the market, and granted the RR is a small market, but they chose to not stay in it, and the AAR wasn't happy with them over it, and by the way the NXDN/IDAS decision came ofter Motorola left the market, not before.
It's the same way with MOTOTRBO, they have to HAVE a product that cannot be made by another vendor. Sure you can get a basic DMR radio, but Motorola is pushing their trunking which isn't even licensable to other vendors.
I like Motorola products, always have, but their sales technics have always rubbed me the wrong way. Stories I could tell you, sheesh.
