I'm not sure the solution is a technical one at all. For instance the ROS users (even many US ones) are still causing major interference to the Net105 packet network. Even if RS ID was appropriate for packet (which it isn't) I don't think it would stop the QRM. It's a complete lack of understanding of what is already present on the bands (witness the NCDXF incident), possibly no comprehension that they are running a 2.2KHz wide mode and then maybe an attitude of "my technology is superior (or cooler?) than yours" even though our network has been operating continuously since 1986.
Can you imagine the uproar if we decided to uproot and choose 14070 for our packet network?! These very same hams would probably be telling us that 14070 is an established PSK31 frequency and to take our mode elsewhere! Do many of our new generals/extras just expect to ride roughshod over everyone else? Or is it a growing attitude amongst more seasoned hams? I don't know the answer but the attitude I perceive seems much ruder and devil-may-care than it used to be. When I was a new HF op I spent 90% of my time just listening and making absolutely sure I wasn't going to cause any interference to anyone. Now I'm an older ham I STILL operate where I listen 90% of the time. If I couldn't have a QSO in a 2.2KHZ wide digital mode because the bands were full of sigs SO WHAT? I would CHOOSE a narrower bandwidth mode myself or work some CW or go fishing. I would never deliberately cause QRM. 73 Sholto
