Considering all the talk about how some countries have moved or are moving to bandwidth specified allocations on the amateur frequencies, it seems to me that we also have to make some adjustments in the way we view digital modes. If you have a narrow bandwidth mode (CW, PSK31, PSK63) and then some wider BW modes, (such as MFSK16, RTTY, Olivia, etc.) and then very wide BW modes (such as wide band Olivia, MT-63, etc.) the bandwidth will determine where you will operate. I question whether there should be sub - subbands for specific modes.
No person or mode has a right to a specific area. In fact, it seems to me that we are moving further away from that construct. For example, while I hear some RTTY in 14.080 to 14.090, it is not that much outside of contests. I do hear some wider modes, e.g, Olivia, MFSK16, etc., just below that area but there is no reason that the new modes would not be able to move into the "RTTY" area if they needed the space. This is based upon activity and not some guaranteed area based upon the mode. By the same token, one would not want to intentionally move into what has been historically considered to be a specific mode area, unless you had to because of the pressure. Just like what happens during RTTY contests and the RTTY folks spread out, or during CW contests and the CW folks spread out well over the digital area like this weekend where you had CW stations operating in the 14.070 watering hole. The other issue is this idea that there can be "channelized" activity on the amateur radio bands. There is no way for the average ham to keep this all straight. The only area that I try to keep away from is the NCDX beacon frequencies on each of the higher HF bands. But to even know what special interests might desire for a "channel," is nearly unknowable without some kind of chart in front of you at all times. For example, I have no idea what frequency the selcal might be for ALE on any given band. As Bonnie has pointed out, they have even moved this frequency around!! The one exception is that they use LSB at the very top of the 30 meter band at 10.150. It is very unlikely that a casual operator would ever go up that far. But I was not even aware of that until a few weeks ago and I bet most hams are not even aware of it. The amateur radio bands are simply not designed, nor are they appropriate, to use channelized operation. The exception is 60 meters with the mandatory channelized voice frequencies that don't even allow CW, nor digital modes at all! Not very useful for hams like me who only have one HF band that I can legally operate on analog voice and switch over to digital if I want to. (Unless I want to send detailed digital images due to the quirky and bizarre current rules here in the U.S.) It might be possible to have a NCDX beacon/automatic station/channelized operation in one highly specific area, but having spot channel freqencies at other lcoations in a given band seems unworkable. The one thing I do agree upon is the need for the three regions to try and work out similar bandplans.
