My organization is toying with the idea of not being a total Motorola cult and they have been looking at the Viking series radios for the statewide P25P1 system we use in Minnesota. In reviewing the product documentation, along with P25P1 and P25P2, they list Viking16 as a capable system voice on the kenwood products. What is Viking16? Just a branded version of something we are already familiar with or is this something novel? I have tried searching the forums, google and OpenAI to answer this question, but am coming up with nothing more than it being mentioned in broduct brochures, but nothing more descriptive.
Viking 16 is the 'trade name' Kenwood uses for Mororola Type 2, 3600baud Smartnet/Smartzone trunking.
Motorola Type 2 trunking was capable of both analogue and digital CAI. It was Motorola's offering/implementation of APCO Project 16. This protocol was discontinued many years ago, although there are still a bunch of Type 2 systems in operation through out North America. That number will dwindle over time as they are replaced with other, modern formats, like APCO Project 25 Phase 1/Phase 2, DMR and NXDN. If it was a public safety user, it is usually replaced with a Project 25 Phase 1/Phase 2 system. If it was a commercial user, it could be P25, DMR or NXDN. Kinda a crap shoot what goes in, DMR is very popular, NXDN, not so much.
EFJohnson received a license from Motorola to manufacture radios that were compliant with Motorola Type 2 trunking protocol.
The other big player in the Project 16 public safety space was EDACS trunking. It was capable of both analogue and digital Provoice. It was GE/Ericsson/Tyco/MaCom/Harris offering/implementation of APCO Project 16. The EDACS(Enhanced Digital Access System) protocol was never licensed to any other manufacturer, and subscribers could only be bought from G/E/T/M/H(The technology was bought and sold a bunch of times before it was finally discontinued by MaCom), although Harris still sold subscribers capable of being used on an existing EDACS system.
L3 Harris now offers APCO Project 25 Phase 1/Phase 2 trunking as a replacement/upgrade to EDACS. Same as Type 2 trunking, there are still some legacy systems in operation, they are going away, and being replaced, mostly with Project 25 Phase 1/Phase 2 systems.
