Dear all,
I agree with most who say that there is no deed at this point for any rigid plan, my only, very preliminary suggestion would be: let us keep the lower few kHz for regular CW, QRSS in the middle and digital modes above, say 477 kHz. While it may be necessary to agree on certain frequencies (such as 477 kHz "dial" for OPERA) I would keep the remaining allocations open, each local locations is different. Also, in the future with more activity I am sure we don't need any CW calling frequency as we will do random contacts, same as on every other ham band.
Just my 2 â?¬-cent.

Dear Klaus,
in my opinion it is far too early for a rigid band plan.
At this moment only few countries are active on 472-479kHz, in 2013 things will change.
Let's wait until then to decide
a. if we really need a rigid band plan
b. what it (eventually) will be

Dear All
as a first proposal for discussion we present a "plan" that we coined the "B31 Band Plan for 630m". The name derives from the DOK to which all who shared ideas, belong.
Just to state it once more: it is a first basis and proposal and those who have an interest in operation between 472kHz and 479kHz (up to now the slot allocated by the BuNetzA to German hams) are invited to agree, discuss or provide better ideas.
Several hams already provided specific proposals which were incorporated.
We deliberately did not detail too much, as we do not think, that all can be fixed prior to actual demand.
Please see attached gif-file.
1. A CW slot from 472kHz to 475kHz (=3kHz).
2. Within that, a region for beacons (472,000kHz to 472,150kHz) followed by a region for Slow CW (472,150kHz to 472,300kHz).
3. For TA-CW DX traffic or other long-haul DX, a calling frequency shall be established at 472,600kHz.
4. For other CW traffic, another calling frequency (if the necessity exists) shall be established in the upper region of the CW allocation at 474,750kHz (474,500 occupied by "SA").
5. The frequency 472,500kHz will not be allocated for special use (at least for the time being), as a continuous carrier is audible 24/7 throughout DL.
6. A slot for Digital Modes from 475,0kHz to 479,0 (= 4kHz).
7. Today it is much too early to decide which digital modes will be used on 630m. We propose to leave this open for the future. WSPR (474,200kHz Dial USB), OPERA and ROS (477,000kHz DIAL USB) have established themselves on the shown frequencies. Some other
modes that may be useful for MW but can not yet be used (e.g. JT65HF) because they allow no suitable frequency selection.
8. Digital Modes should not overlap each other (minor relocations may be necessary).
9. Whether or not the shown "protection zones" of e.g. +/- 50Hz around active NDB frequencies are necessary or not, ist still being discussed.
10. No further stipulations will be given.
