The  more  one  looks at  this , the  more  sensible  it  becomes  ,  I like the  idea  of  a  wide  band  mixed modes   area   474 usb  ,
 
As without  any  formalities  we  can  see  the  more  primitive   modes  are  congregating  in the  centre  of the  band , assumedly necessary  prevent out of band transmissions due to  vfo  drift  or the  like  ?

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.
