UBUNTU Virtualbox AD9850

June first week no interesting DX 50 or 4m  dead bands most of  the time.
Gray skys cool and some rain after our punishment for the one day summer..  
Boring  all bands closed short wave and VHF!
Time for other things.

 Ordered 3B9FR QSL by  the paypal service of M0OXO ..
first time I used this to get 

Checking  6m DXCC confirmed it is a bit.. behind  170 cfm'd of 212 
I wonder if I ever can get those old cards 
Somewhere I strongly feel that the 3B9FR was the only new one this season.
the other opening??  30seconds ???  to 5Z0L was missed.
That morning I was working to improve the 6m antenna mast was down bad timing.
Now the 4 ele seems to work more optimal very directional  hopefully it brings the dBd that
matches the hardware  about 4m50 boom.


Only surprise was that one warm evening  I was called on the local chat frequency 145.525MHz
vertical 10W  by M0TLX Dave in IO94hw 500+km 
Even better signal at 433.525MHz like a local!


I had to give up on UBUNTO  very sorry  but it crashed  to often on the Lenovo
It can work so nice but after some time a day an hour or so the keyboard touchpad are switched of
An a reboot is needed.   
That could be the hardware of this Laptop of course.
But keyboard did not had problems in Windows before.

UBUNTU message popup say that an internal error in UBUNTU did appear  so it is blaming itself for the unknown error?

Then I am asked to send a feedback but..  the Wlan adapter is blinking but won't connect anymore  
after a while it says you are now offline...  good to know I did not notice...
Mostly a loud beep is given  in such cases just to annoy you!
Then there seems no remedy new start didn't help
Possible there was an system update again that crashed it?  I had that before several times.
A real pity either it is the Lenovo hardware or  UBUNTO does not like this Lenovo.
b.t.w. this Lenovo has a beautiful build main-board it looks all okay to me.
Will test UBUNTU on other system to find out if the Laptop hardware is the problem.

The Oracle Virtual machine latest is running fine with W10 
It can not run simultaneously with MS-Virtual XP / PC
the Virtualization Technology (Intel® VT). 
Does not share 
I was not aware that MS-Virtual PC  did use this  it was not mentioned  and does not need to be enabled in the BIOS?   Virtual box needs to have it enabled in order to run a VN with Win10
Strange things happen!
  • New June 1st, 2015
    VirtualBox 5.0 Release Candidate 1 released!

    Another Beta for the upcoming new major release, VirtualBox 5.0. Seethis announcement for details.


Urduino DDS VFO  
The AD9850 board from China arrived by mail
Including shipping about  7€    How the Chinese manage that is a questionmark
The header connectors  seemed of bad quality and maybe later assembled to the PCB
Corroded and some pins where not even fixed.
Might remove those headers .

looks like this but with bad soldering headers..




I can not use signs in the text HTML will make rubbish of it..

2011-01-22 DIAMOND 2m 70cm 1m30 Colinear inside

Having relative poor signals on the local 70cm / 2m channels using this X50 Diamond collinear 70/2  1m antenna at a height of 25m. I needed to investigate what could be wrong. Measuring the cable only 3W is left for the antenna of the 10W 435MHz output from a IC451E The cable is 30m type H100 Z50 10mm outside diameter it is semi air-spaced but has an impossible 4mm² solid CU inner conductor not much air left. I preferred the H43 Z75 cable having lower loss and mechanical better ratio in conductor size. My antenna uses SO239 connector UHF type semi air spaced isolator.  3W should be enough for a comfortable noise free FM signal. But only 27km away at PA0A the signal is weak too weak something must be wrong? I made a simple reference dipole of 2x17cm CU wire. With this dipole the signals where totally worse. So the Diamond does work? I got curious to look inside. Maybe moisture penetration degraded the antenna. This  antenna is rainwater close in its n...

SPF5189z Low noise preamp 23cm

 14-4-2018 updated Above the low noise  preamp 50 - 4GHz    ebay  6€ Tested  2 small porto antennas 1 Baofeng UV antenna left   2nd best signal on PI2NOS 2 eBay DIAMONDSRH805S  wide band 144/432/1200  it works for its size as expected 3 piece of wire :   best signal in the setup... Unit under test at workbench. It was stable  50mA  at 5V   few days,  but sudden the current went up to 100mA And i could  no longer adjust it with the negative bias Voltage. The - Voltage went to zero and the SPF input port became low Z. This SPF5189z was broken  no oscillations, no input overload just it broke while i was receiving the PI2NOS 430.125 using a small antenna at the workbench. The specs of  SPF5189z  say it has an internal circuit  regulating the bias current. Replaced . again   with an other of the 5 spare SPF i have. The new one again could be adjuste...

BIJZEN mast en ontwerp fouten.

In 2013 heb ik een Bijzen aluminium mast 3 x7m  opgehaald  bij iemand die hem niet mocht plaatsen Gemeente Oss  dat zegt misschien al genoeg.. Pas in 2018 heb ik hem geplaatst had ik veel eerder moeten doen. Mooie mast, mijn xyl vond hem zelfs mooi. Hij is licht, de 3 delen wegen  235kg  het vaste deel 102kg dus het te lieren gedeelte weegt   slechts 133kg + ca 50kg rotor + antennes etc.  De elektrische lier is wel erg zwaar 30kg misschien wel maar die zit onder    Antenne  3ele Steppir  19kG  +  G2500DXC rotor: 3.6kg  + rotorbuis 12 kg  +  kabels 10kg  + 5/7 ele 6m beam. ongeveer 50kg Je moet niet te dichtbij  kijken, dan valt op dat het Aluminium lastwerk heel slordig is gedaan, scherpe bramen aan de lassen waar kabels door kunnen worden beschadigd of haken Er is zeer ! weinig ruimte voor de rotor een YAESU G2500DX past net maar dan ook net  met beetje buigen van  kruisverband.
