Windows 10 running in a virtual PC and projects .. a lot

The easiest way to explore Windows 10 is installing it in a virtual PC
That is what I read on the internet i agree with that.
Already longer time using Windows Virtual PC  XP  for Simatic S7 PLC software
That works fine.
Simatic software is not what you want to install in your system since it is
short said:  a real pain in the a..  type of install
If "lucky" and Siematic is installed it takes over your PC  with crazy demands like:
Forbidding  to install service packs or anything the Simatic Haub kwartier Befehls..

I also have W2000 in a virtual PC but never used it since W7 is good.

But my attempts to set up a virtual machine  or PC  for Windows 10 id not succeed

Windows virtual PC  install of a W10 iso  32b or 64bit  ended in error :
 it shows the W10 startup logo then after some waiting
the error message end the attempt

Then I tried Oracles virtual machine or virtual box what ever they call it..

But with every attempt the setup is aborted  (as administrator)

The links to try to resolve this problem are broken!

It still is a big challenge  to run the t-preview of W10...

I never tried W8   i did not see any advantage to install a new OS that has less functionality
against W7
Reading the articles about W8 confirms my impression about that.
 W10 is a repaired version of W8

Now I am writing my diary..what more things i came across:

Trying to refurbish an old guitar.
With new snares.
When watching TV a sudden very loud bang from the corner where the guitar stud.. a final chord.

Now at this point it would be nice to easy insert pictures using Googledrive?
Google+ ?? That took over the former Picasa webalbum that I used before.
Or how they are all called I get confused by programs that have almost similar names and functionality
Picasa did not made it easy using pictures with your blog or mail.
First you had to "export" them and choosing a format/size.
Google drive seems still in development might be good in future it is strange that this Google blog can not use google drive?
Dropbox does work if you manage to find your saved picture back. let's  see
i started my attempts  at 11:10..
importing from Google drive is not possible as expected.
importing from dropbox is possible but the pictures uploaded never arrived
so again HTC share to dropbox..
yes it is 11:33 i have the pictures  must be the aging...

Guitar cleaned and with new steel snares   sounding great again! 

But after 1 week it ended in a sudden bang
I red about using steel snares on an acoustic guitar some say they use steel snares without problem
but others report  damage like this.
It seems that the steel G string needs more tension to tune.
All  together have 20kg more Nm to the nylon.
Now i learned my Guitar is made of red Cedar because there was the typical delicious sweet smell  of red cedar this wood is strong and light but its fibers did tear apart  too easy.
I once made a ruder blade of red cedar wood,  fantastic wood I did no found the fibers come of that easy then
So no steel for this guitar..

An other partly success   my car project
the repairing of the Opel Vectra B caravan 16V16 .
The parking brakes are replaced.

the reluctor rings only 2€ each!  but I have seen them for 45€ also.
They fit perfect after heating just a bit hammering to position
But to get this wheel axes in out and in is an other story.

 The parking brakes replacing them  needs 4 mecanic's  3 of them trying to control the springs of this very primitive system while the  4 places the brake shoes
They cost only 10€ 4 pieces..

The ABS error is gone after placing a new "reluctor ring" .
But I can not yet get the last air out hydraulic system.
Repairing older cars not being an oldtimer is economic not attractive since prizes of  2nd hand cars including an approval paper is very low  for 1000€ it is possible to get a good driving approved car.
The government changed the rules for oldtimer tax back to a normal car  = extreme level
So another thing that makes living a bit more pleasant is taken away.
For no other reason then the economic.
Owning a car without driving it is punished with 100-200€ / month.
 Cars and life could be a lot cheaper but our alone our tax administration  is bigger then the one of f.i. Canada and needs endless tax.
And still the fuel prize is is higher then in neighboring Germany for what reason we are both in the
EU  the fuel is shipped in from Rotterdam
Euro95 fuel     DL i= 1.42€ / liter   NL 1.58€/l  today 3-5-2015  as long as I know it always was cheaper in DL
A simple economic calculation our € is 11€ % cheaper the the German €

An other project that was on the shelf for some months.
Finished my Arduino SWR/Power meter project almost...

Building it in a decent case and making it work took more time then thought.
It is quite difference assembling a nice complete kit  like the component tester
Even assembling the K3 was easier!
But then that's the electronic hobby to find out and puzzle how to get the best result.

first with D9 connector this I did not like

display backlight is automatic activated upon signal

Did not utilize a standard shield but soldered the UNO direct on custom experimental board. 
saving space for an 9V battery option  i have to take it apart again to cut of the board..
 I did use the colored connection wires and header pins to make it easier assembling disassembling.
These came also from mini in the box China very cheap but the connectors are low quality.
Preferred  the old 5-pole-DIN type connectors  over the D9  data types.
The mini din would be good too possible. 
The power is applied over the mini din USB the HTC type 

using 5pole DIN now with the detector part direct on it. It can be taken out together with the connector that makes it easier.

It works but I have not seen  yet an SWR value other then 1:0 ..
Both input channels seems okay A0 A1

And found that the directional voltage out is a bit too high with the used toroid transformers.
Possible the AL is to high for this.
8W 145MHz  gives 6V already   and the Ge detector diodes have restricted reverse voltage 30V abt.
So need to replace this trafo's
Even at 475kHz the voltage was way to high.
But... hmm the Voltage should only depend on the transform ratio not the  permeability.
I have 2x 100ohm chip R 0.5W parallel to terminate the current transformer.
So why to high Voltage have to reduce the winding ratio

Then still have not been able to fix the 4M PA
I replaced the damaged BLF177  easy with the SD2931-10 type a similar  50V 150W type MosFET
Could adjust the bias again at 0.5-1A  though i had to reduce the gate control voltage quite a lot against the BLF177 Phillips type

The same output result max 100 120 was reached
But then...
I switched the TX to off  without output  and bang!  somewhere  no fuse blown
No more bias no more output...  the FET was blown without over current.
That could be over voltage but no power applied at the moment of switching.
And this T/R switching does happen many time during normal operation.
No oscillation issues  since i modified the gate drive circuit with a  balun short piece of thin coax through a bin-ferrite core VHF type AL
The BLF177 since that mod was working unconditional stable
Though the efficiency was a bit low 50%
Dutch RF design reaches over 60% when asking them about.
Possibly not using  ATC capacitors in the filter part reduce the performance.
But now I have 1 SD2931 left but dilemma i do not dare to test it.
Power supply voltage 13.4V 55V (unloaded)  is normal no fault
By passing the PA now having max 10W

Must be Murphy law that strikes again.  After working without problems 1 year and more now it is kicked out just at the start of May where the ES season supposed to start..
I think the NXP Philips BLF177 is more  stable  then the SD2931
Since this BLF177 is working in the same condition for 2 years and also was exposed to oscillations mismatch during building the PA.
I could run key down long time with 120W without overheating.
But I never could bring the efficiency from 50% to a more acceptable figure like 60%

Dinsdag middag 28-4 15:50 bliksem deelt een tik uit.

4m transverter eruit
PA en preamp naar de eeuwige ruisvelden door onweer ontlading in de omgeving.
Verder geen andere aparatuur met schade kunnen ontdekken.
de K3 was ook op 6m WSPR
Niets gemerkt pas vandaag zag ik dat de 4m transverter wel erg ruisvrij was en geen bias in de PA.

de laatste decode voordat de bliksem de Tranverter uitschakelde
2015-04-28 13:46  PA0O  70.092524  +13  0  JO33hg  1  PE1COS  JO33ge  11  211

de  BLF177 heeft geen bias meer BE spanning 3,5V 
jammer shit happens

Ik denk over een spanning surpressor in de antenne kabel.
Hoe nu juist de transverter geraakt is en ( gelukkig  )  niet de K3  dat is niet duidelijk
De K3 heeft wel surpressor dioden op de antenne aansluiting.

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.
list disk

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

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.

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.
