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.
