Hi Stefan,
for the broadcasters LF (and MF) is the past. LF / MF transmitters and their antennas
are very expensive to maintain and these days the audience is small.
More and more LF / MF broadcast stations will go QRT.
But let's look at the good side: apart from less QRM it
is likely that in the future there will be more space available in the LF
/MF range and the ham bands can expanse or we can even get new bands.

Hi LF
,
Obviously
there
was a decision
that
DLF
(Deutschlandfunk
) will
go QRT
on
LF
153 kHz on
31:12.2014!
Here
is a German
article
about
this
decision
:
http://www.radiomuseum.org/forum/dlf_stellt_langwelle_ein.html
This
makes
me a bit sad
on
one
side
since
i
like
the good
old
AM radio
stuff. But
on
the other
side
, i
know
that
i'm
getting
QRM
from
that
transmitter
which
runs 500kW
on
a 350m
high vertical
antenna in 40 km
distance
. Probably
there
is a significant noise
spectrum beeing
radiated
which
i
can
see
in that
short distance
. I can
see
it
just
a second
before
20 o clock
in the evening
, when
they
switch from
500 kW to 250
kW. For 1...2 seconds
, the AM carrier is off
air, which
lowers
the noise
background significantly
. So
maybe
LF
reception
will
be
much
better
next
year
, i
hope.
So
maybe
it
is worth
for
some
to listen for
the last minutes
of DLF
LF
transmissions
on
31.12. this
year
:-(
