hI ...
The thermostat swinger is "strong" in a Vietnam KiWi SDR
Propagation not ok tonight, no signal from this "reference" here
now ...
I have 3 carriers detected, all stable and close to center freq
(.5Hz differece) so hard to say who's who.
I don't have a GPS reference to verify my own calibration. May be
some comb generator from a pps helps.

Morning
from Alaska - I was a little late in shoving the North
bound beam over the pole and taking a look at 1476kHz -
We have numerous co-channel stations on Oz, China,
Indonesia and Russia and I tried to reduce them using
the K9AY but I dont think Im seeing anything yet.
It
wasnt a particularly good night . Ill take another look
at sun down in a few hours. Notice the abrupt turn off
for one or more transmitters, and someone LF of
1476 appears to have a lot of recurring on/off/wobble
about... I also have a 1Kw station within a mile on
1430 which is putting out some low freq rumblings which
isnt helping.
It
does Happen occasionally as Ive heard Moray Firth and
North Sound radios on MW from this side.

Hi Lubos, Dave, Chris, great news! Thank you so
much for listening and reporting.
Chris, I'm pretty sure that Ralph will love to
read about your receiver!

Von meinem
Samsung Gerät gesendet.
After the sad
demise of all
LW and MW
broadcasts in
Germany, a
handful of
pioneers came
up who are
operating
legal
low-powered
medium wave
stations in
the context
of a radio
museum or
for educational
purposes. One
of them is
Ralph (DL2NDO,
one of the
participants
in the
legendary
Donebach 137
kHz activation
in 2002).
He has
obtained a
transmitting
license for
1476 kHz
(former
frequency of
Vienna
Bisamberg), built a
3 Watt AM
transmitter,
and with the
help of a
small team
raised a
quarterwave antenna
on the
Fraunhofer
premises south
of Erlangen
(JN59MN21HF).
Yesterday they
got on air for
the first
time, running
a preliminary
test
transmission
consisting of
switched 1000
Hz beeps (one
second on, one
second off,
audio
frequency
locked to the
RF carrier).
This pattern
will
be continued
for a few
days, before
they will
eventually.take
over the audio
from the local
DAB student
radio
"funklust".
The current
test pattern
is relatively
easy to make
out in the
noise so it
may be a good
chance for
some DX
detections.
At night
we've actually
heard the
beeps
on Twente SDR
and a couple
of German
Kiwi-SDRs. But
I guess
using narrowband
signal
processing
techniques,
the carrier
and coherent
tones could
make it much
further. The
carrier
frequency is
derived from
an OCXO and is
currently at
1476000.411
Hz.
Will anyone in
the group take
the challenge?

Markus (DF6NM)
