In a message on Sunday 01-16-16 Richard Menedetter said to Tom Walker:

Hello Ricsi,

RM> I am for example talking about D-Star/DMR/Fusion.

RM> There you have 3 possibilitites:

RM> 1) talk on simplex HT  HT over radio waves (talk around on DMR)

So far that is OK, but I don't understand what (talk around on DMR) is.

RM> 2) HT  repeater  HT over radio waves

That is also ham radio.

RM> 3) HT  repeater 1  IP  repeater 2
 HT all over radio
RM> except the IP link between the 2 repeaters. Those two repeaters can
RM> be seperated by thousands of kilometers or whatever non-SI units you
RM> like.

This is where our opinions differ. As soon as you involve an IP link,
or any other transport other than radio waves, it ceases to be ham radio

D-Star, DMR and Fusion are communication methods between two parties,
that don't use radio waves for the entire link.

Read also in QST 12/2015 p62 about the future of digital communications.

RM> From MY point of view having the possibility of using option 3 does
RM> NOT disqualify those technologies as being HAM!

Neither D-Star, DMR and Fusion qualify as ham radio as soon as they use
an intermediate transport medium, other than radio waves!
