Beverage and software issues continued

West-Beverage in use now some weeks  works real good.
But the east direction was missing. At least switching E-W must be possible .
F.i. 16 December 160m  lots of  JA heard some 599 but deep in the noise on the TX  antenna.
Tried a bi-directional Beverage last year but the result was no success.

So now i set up a 2nd  east Beverage Saturday I need to follow the east west pattern of the ditches avoiding crossing the land strokes s
As long as catle is on the fields only E-W Beverages are possible
I  had 2 wires about 330m long former army field telephone wire  twisted..
Steel wires with CU   core  20 OHm / 330m very strong insulated wire perfect for Beverages .
It was a touch job to untwist a 330m line..
Now i could pull relative easy  the 2nd  wire from the West Beverage to use it for the 2nd East Beverage.  Relative easy...
Most work in the dark it is special setting up Beverages good training too. I walked at least 4 times in both directions. 4x 700m over wet grasland. I imagine how this will be at dx-peditions sites walking in the bush snakes wild animals... But here in the Holland climate we have little dangerous animals in the fields most dangerous animals if any are found in the city's.
We once had a lone Wolf wandering around lost from Germany  never caused problems.
Maybe the global heating will change that..  But the global heating is stopped now by the agreement  in Paris  the temperature will not rise anymore we only have to pay a few 100 billion tax more and
some new crazy unworkable EU rules will be forced upon us and we are safe...

Careful this time still a little muscle strain of my last Beverage action.
For east I have to cross the driveway. Already a cable was under ground  to the other side.
I modified my bi-directional Beverage switch-box so that I could switch between B1 with its 9:1 trafo or the 2nd coax cable to the east Beverage

Both Beverages seem to work tested on some signals  E/W   but
 160m / 80m / 10m propagation  radio blackout so have to wait for restore of ionosfeer.

The shack switch box   injects 12V  to the cable   to switch the remote relay.
I used the box that I had from the K9AY.

The  antenna box in the field  switches  between the West and East Beverage.
The west  B is direct connected to the box. The east is connected over a coax cable
It can be any other  50Z type of receive antenna.
The simple circuit took me some trial and error to get it working.
I should have taken  time  for a good circuit drawing first before starting to solder.

S1 is optional  to use  or by-pass J4 /J3

the software issues continued

1 Solved  LOTW   upload failed after renewal of certificate      is solved with help of LOTW team..
   my certificate was not valid after renewal..

2. reported to
new versions do no mention this issues
N1MM+   overflow rte when re-calculating  score of general big log
  no response from N1MM team not sure if  report is received.
 - hang-up in general logging / huge logs score calculating give overflow RTE
   still using n1mm classic for that reason.
System.OverflowException: De rekenkundige bewerking heeft geresulteerd in een overloop.

- not switching to actual mode after closing digital  mode.
- not being able to force logging contacts with ctl+alt+enter
- refusing to import ADIF with missing records.

3  Solved      Scanning documents on the Brother DCP750CW workes again
 after un-installing Adobes flashplayer

 Before tried  reinstall the Brother software  and re-booted the PC  no cure.
 It is  another GUI for the Brother Control-center  but the functions are visible and function again

Now I am sure flashplayer caused this problem
This remedy worked too on other laptop W32

New this weekend...  scanning a document on the Brother DCP750CW  printer
  is no longer possible.   Control center  utility  of Brother can do that I use this for years it always worked fine
  as long as the Brother  DCP750CW is in the same WLAN  subnet.

But today sudden the Control center wil not work.
It opens a white field controls are gone .  same on a second PC!
I suspect  Adobe player since l-m button displays a message related with f-p
Is it Adobe flash player with a new update   update 24588532908876627 since this trash player needs updates every 30 minutes ? This Adobe flash player is playing around with your PC.

  B.t.w.  the DCP750WL can only connect to an open Acces-point.
It failed to a secured WLAN      WEB  or   WPA2 . But okay    i placed a 3rd open WLAN  router just for the Brother.
  WLAN  is a very difficult technic.  If it works you are lucky  It can stop working anytime without reason..

4 Solved  fttb  ..    N1MM  suddenly very slow responding again
It worked flawless in CW the last contests.
Now in the Croatian 9ADX   the mouse cursor hanging slow move delay of seconds lost the cursor then.
TX cq did not start but many seconds after pressing enter.
Typing the call or report  nothing happend.  but  5 -10 seconds later just a part of the call filled in.
Total unworkable. Reboot did not bring anything.
 Then I disconnected my external HD  1.5T  USB3 and I was back in business!
Keyboard mouse and CW normal quick response no noticeable delay .
For unknown reason the external HD slows down the PC drastically just being plugged in
without known activities running.
No MS-essentials scanner running.
MS system monitor does not show all processes that load your system
It will not report :  Windows  process xx  is delaying your PC ....

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 adjusted at 50mA  5V 
The current raises to 150mA  when removing the  negative gate voltage.
Where is that internal bias circuit ?
I suspect  eBay …

2011-01-22 DIAMOND X30 2m 70cm 1m30 Colinear inside

Having relative poor signals on the local 70cm / 2m channels using this Diamond collinear 70/2 combi 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 but it is no longer selling i think. This H43
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 normal vertical mounting position. But take care if your mast can b…
