It will be interesting to see if the ham manufacturers decide to start producing equipment for DMR. I expect if anything it may be someone like the Chinese manufactures to who come out with the first equipment. Then if it catches on you may see Alinco and others start into it. I don't expect Yaesu or Kenwood to be the first. I think that they would want to see how it is received by the general population before sinking R&D into it.

This is similar to how Packet Radio started. For the first few years you had to build your own kit from TAPR, (my first TNC was a [I believe] a TAPR-2 kit), and then they started to produce fully assembled units. I remember that when TAPR introduced the the TAPR-2 it caused such a tie up of the phone lines and no one could get through that the phone company though their whole system crashed and they sent a team out to the switching site to see what broke. The phone system could not handle the in flux of calls. Probably the first "denial of service" problem long before the internet.

Finally MFJ and Kantronics saw that packet radio was catching on and they started to introduce their own TNCs. I think MFJ licensed the TNC design from TAPR.
