One of those rare nights with longpath to VK at 28MHz



Woow  when I entered the shack at 23:30 CET almost midnight  found 28Mhz still wide open
VK2ZMT VK4CZ over no doubt longpath!
Why must this be longpath? With a dipole the back and front is equal receiving but the regular morning  North-East path is the dark side of the earth or better said the no-go area for 28 and 50 MHz
As we know all too well in North Europe that  we are not hearing any of the 6m DX that can be heard  in the south of Europe for months now.
And if the dx path would go over the North-East we would be the first to hear it .
We have to wait for Es layer to extend the south EU propagation to us.
And then when we finally catch one of those rare ES extend TEP openings we are at the mercy of the south Europeans to get a break in the pile or the DX must have ears for the weaker dx behind the wall.



That means all distances have to be corrected  for us in the north the path goes over south Europe
and not the other way around
So 16452  plus  2000-3000  19000 km roughly

and for the EA CT stations  minus 2000-3000km    not plus as it is always wrongly assumed the  SW EU  path is going over the night side of the globe!

4m 9H1XT new one

My first DX result with the new 5 ele 4M Yagi..
new one in MS FSK441  9H1XT jm75gv

QRB  2028 km  a bit far for MS one of the best m.s. distance worked.
but right in the first minutes received 2 very strong bursts almost too strong to be true
holding several times both callsigns
But after that some long weak reflections received only in over 30 minutes
and not good decoding  fractions only with R26  but hmm not 100% sure
sometimes the random noise displayed likes to favor plausible data like 73 R26 etc..
 but then after many empty periods  a clear R26 + call was decoded
 and finally a new one in the log
Thanks John     I think in the ES season if we have one.. 9H1 will be regular workable
I remember long time ago that the first 144MHz  9H was worked in the 70's that
was sensational dx then.
There are more 9H active at 4m

Windows10 experience


 I did install the technical preview of Windows10  on a separate HD
After some puzzling how to make an boot-able external HD
A process that is complicated in Windows.
 I had my old W7 HD  backup since replacing it for a SAMSUNG SSD 500G EVO
SAMSUNG has its migration tool to move a complete HD  to the SSD ( SAMSUNG SSD only)
From a running W7 system without any problem.
No need for disk image boot CD.
What I was looking for was a simple way to repair my W7 HD where Windows was deleted
Just copying back the Windows map is way too simple...
Just because some parts are missing the drive had to be reformatted destroying installed software Throwing through the window all the time spend on installing those parts.
Making a bootable usb / HD W10  a lot of discussion can be googled  about this subject.
more methods can be used but a very simple method does not exist.
Easy BCD 2.2 of Neosmart supposed be able to do this easy but I could not find out how to make sure what drive I was making boot-able confusing and to risky to work with.
Why is it still needed to follow the relative complicated way
with the power-full dos commands also risky.
diskpart
list disk

select disk x (X is de driveletter die overeenkomt met de USB HDD)
clean
create partition primary
active
format fs=ntfs qucik
assign
exitk


Mount de Windows 7 of 8 ISO Image in een Virtual Drive. Dit kan met de freeware applicatie MagicDisc
De USB Drive Bootable maken.
Ervan uitgaande dat H:  de virtuele drive letter is waar het ISO-image van Windows 7 of 8 is geplaatst en G: gekoppeld is aan de Externe HDD.
Open de command prompt en voer de onderstaande commando's uit.

h:
cd boot
bootsect.exe /nt60 g:
Why SAMSUNG migration can do this automatic?
anyway i had to reformat my old HD since it did not want to boot W7 anymore.
An upgrade W7 to W10 could be available short time.

I moved W10 to the HD and installed it
The HD was bootable when placed in the SATA slot of the LAPTOP
But it did not boot as USB device.
The W10 logo came on and the waiting circle but nothing more.
The disk activity LED stopped blinking and went to stable on.

But with the drive intern I could run W10
Installed VB6SP6   using a special installer for that.
VB6 IDE did run but the data environment msde.dll did not install no reason given.
Could not do a complete test without connection to a database.
Then last evening W10 did an update and after that i could not start
it needs repair  but no repair path was given.. it stays in an endless startup loop
My W10 experience was ended after last night.
But tt looked okay W10 the start button was back and VB6 could run the IDE more the in W8

Tried to install the W10 32bit version
but got struck with this message

 a hopeful start...
but then after 10 seconds





VP8ALJ  new one 10M WSPR

Wanted to ad picture from Dropbox and or GoogleDrive
but those programs sometimes do not show all uploaded  pictures.
Also vague in what map you upload 
It is can be very useful if it works right to access files
Google drive does not integrate with this Google blog yet.
Dropbox files can be selected as a local map but not all files are shown
Even after the message:  file added to Dropbox comes up after just uploading a phone picture.
The uploaded file seems not synchronized with this PC.

 TONICA RX80 former DDR Rundfunk Empfanger

I got this receiver for repair  and was surprised by its design 
The 2A fuse was blown for the +/-24V unregulated power to the PA part
But after connecting the power again trough a protective 50OHm the bias was low 200mA adjustable
0-500mA  all looked fine 
And the sound was very good.
Fine clasic receiver

It will be not to long from now that all those clasic FM receivers will be ready for the museum
Since DAB+ will take over
So after loosing the analogue TV  the next is loosing Analog FM BC.

Antenne


on top 2m/70cm colinear
5 ele 4m dk7zb new
HF 40-20-15-10 +6m  4ele combi

the 5 ele is a 50Ohm design 3.04m refl. to dir3
the 4 ele is parasitic coupled to the 4band HF dipole ( 9m60 long  40-10m)
 matching is perfect f/b is very good  almost too good

but no results yet on 4 or 6m  propagation is absent  as before
bands are closed

picture taken with Nikkon D70S
some dust spots internal in the camera
anyone knows where and how to clean the optics of this Nikkon?
it is not the objective lense  and not the 1/2 reflective mirror
the dust is sharp focused and always the same spots

propagation 10m propagation lost but 160m surprized

today Friday 17  complete radio blackout not a single 10m spot
80/160 max 2000kM  Rusian spots maximum
Moderate storm A=43
 even tropo is absent  LX0FOUR  OZ7IGY  70021 no signal...

after weeks running almost empty on DX  just very few USA decodes
must be the Solar eruptions with weak Aurora that cleaned up the E-layer?

160 propagation better then 80
