For the same reason the SSB guys insist on using 1840-1850 ...
with their significantly smaller band (1810-1850 in some cases)
Region 1 put digital between CW (1810-1830) and SSB (1840-1850).
With what is left of the "DX Window" at 1830-1835 that left
1835-1840 for digital.
It's an unavoidable fact of life that new activity will go where
the existing activity is. Look at digital on 40 meters - it is
almost all between 7030/7035 and 7045 because that's where the EU
and JA stations are. 160 is no different, digital activity in EU
is 1835-1840 so that's where everyone else will be if they want a
chance to work EU. As much as it pains me to say it - if you
want to fix the situation get ITU to expand the 160 meter band
in Region 1 and convince IARU Region 1 to relocate both digital
and SSB activity higher/into the expanded band.

lot of the 1840-1900 area but 1900 to 2000 is usable isn’t it? I rarely
hear much up there and 3 or 4 khz up there would never be missed.
Probably not an answer but it has seemed strange to me since they
started operating in that area. Some of their signals are bone crushing
and wide. 73 Mike K4PI
