Hi Dimitris,
Thanks for the informations.
Well, if 475.7 kHz is not a good choice due to QRM in VK, then "we"
should discuss where to go.
"We", that must be explained. I think that "we" are those active
stations who either want to try to receive a station from VK or want to
try to get a decode in VK.
Of course i would like to join those active TX stations on MF and i
like to try if i can leave a trace or decode, not only in the sand :-)
I thought about running QRSS-10 near 476.170 kHz, as done in the last
months. This would allow me to run the TX during the complete possible
time, arround 15:30...18:00. Or, alternatively, i would like to run
WSPR-2 in 100% TX mode. That would at least require splitted RX and
TX bands on both sides, otherwise there will be complaints. There
will be complaints anyway, im afraid...
So maybe it would be an idea to define a special slot just for this
path and time and active (RX and TX) stations so they can all run
WSPR-2 in 100% mode. Of course there must be stations who are RXing
exclusively but there are only a few who will TX anyway.
Any recommendations / ideas? Should we discuss in direct emails
including all those from VK who are not member of this group?
I would start the MF experiment tomorrow.

Hi Markus,
I have suggested to the local VK group to switch to radiated rather
than wasted (LOL) power :-)
Staying on a different frequency slot may be at the end what we will
do. It seems that 475.700 kc is a "noisier" part of the spectrum, and
many listeners in VK have complained about that. I will go with the
flow, whatever the group decides, I will do. From the receiving
perspective, leaving the WSPR on 475.700 kc is tempting, given the
density of decent signals emanating from Europe. Especially now that
we have an indication that it is possible. This probably will make
more sense in our winter.

Hi Dimitris,
sorry for that. I noticed my error after I sent out the first mail, my only
excuse being that I was pretty much overwhelmed by the fantastic news.
Yes I saw that wspr activity is on the upsurge in VK. Stefan and I discussed
this this afternoon, and one thought was that keeping split bands might be a
better idea. When several stations engage in two-way attempts in the same
subband, the receivers will be likely affected by overloading and
noiseblanker desensitizing effects. So you might want too consider staying
with separate slots.
There was some uncertainty whether Dale's 50 W tag was meant to be TX power
or ERP. Hereabouts we've sort of settled on stating ERP, simply because
radiated power is the relevant quantity for SNR, whereas antenna
efficiencies can vary vastly.

G'day Markus,
just a quick clarification - it wasn't me, it was Dale VK1DSH that
transmitted the famous packet received in France. Since that incident,
we changed our WSPR frequency to comply with the European one and we
will be transmitting as often as we can in order to find out if this
can be repeated! Dale is radiating similar amounts of RF to me, which
I calculate to be around 0.5 W.

Wow, that's excellent! I wouldn't have thought this is possible.
Congratulations to both Andy and Dimitris!
Best 73,
Markus

>From F6CNI :
Hello, I give you some info about the MF reception of Dale VK1DSH signal
here in France.
For 2 weeks, the propagation between EU / VK on 160 meters is great, and I
had some CW QSO barefoot. I think that for this DX path the propagation on
MF may be similar than on 160 m ?
At the date of this event, between the Dale and Andy QTH, the best moment
is
a bit before the grey line sunset in France, when the sun elevation is
about
3°. But on 160 meters that needs especially good propagation and the
opening
is rare and very short, 5 to 15 minutes only. This moment is now around
1645
TU in my QTH. A bit later, when the sunrise at VK land in grey line, that
is
a second short period for success, around 1920 TU. That is true only for
south to north hemisphere DX.
For north / north path (EU to east coast or centre of States) the best
moment is simply in the middle of the night. But perhaps for longer path,
as
west coast the sunrise in Europe is better ?
My garden is quite large but in centre of the city, a noisy location.
Antennas for LF / MF are an 85 meters long Inverted L and a K9AY. RX are
IC7200, IC706MK2 and a FT1000MP.
Only 3 miles away from my home, there is a golf. That is my second hobby.
Due to the very bad weather in France for one month, there is a very
little
player’s activity. So a week ago I hang on border of the golf a simple
beverage using a very light wire. About 500 or a bit more meters long
aiming
to 80° azimuth. For the test yesterday I had in my car the IC7200 on 473.5
USB and a portable computer (only 2 hours of autonomy) with 3G. I stay on
place only during 40 minutes. That is the story. I catch one spot from
Dale.
What that means ? The Beverage and not power line helps a lot giving a
very
low noise level. The use of the 473.5 USB QRG is good, because there is
not
any QRM on this frequency. And certainly a great propagation day, so I was
lucky listening the good frequency at the best moment. What about the use
of
long period of TXing, as WSPR15 or QRSS ? For this very long path, I think
that the opening duration time is too short for that use ?
Now, as Dale said to me in a mail, one spot is not sufficient to valid
that.
So, I’ll try again but it is necessary for me to hurry, because the
beverage
antenna must be dismounted in a short time.
For information, I use some codes when I am receiving LF, MF or 160m:
F6CNI : normal, listening only WSPR2
F6CNI/2 : I am listening both WSPR2 and WSPR15 (giving F6CNI/15 reports
for
WSPR15)
F6CNI/RX1 and F6CNI/RX2 : I use 2 RX with 2 RX antennas
F6CNI/BEV : one RX is using the Beverage on the Golf location.
Best 73. Sorry my poor english.
