28 back to life ... 1 day only


Saturday 1/9/2012 morning 28MHz propagation map including  EU ZL (not here)

RUS RADIO RTTY   several JA contacts 28MHz 
In the evening 28 showed remarkable propagation.
FO4BM  around 23 local.  Weak on the dipole.  Missing my Stepper.  
XE1KCS/B EK09   OA4B 28.200  heard
Very weak heard  ZL4TEN 28.228  over SA 
just realised to ZL is always longpath..

Need to get  a 2nd mast again for the Steppir.

High expectations for the Sunday morning 28MHz opening to VK/ZL but only "normal" propagation left  with VK2KRR and VK6DZ copied

My procedure to handle a picture  in windows
With  ALT + PrtSC key the  active window is copied to the clipboard. But  using ctrl + V  does not place the bitmap image to this blog. 

I tried MWsnap  to select and copy a part of the screen.
Then this picture is saved somewhere  to  your user files
It can not be found in the "my pictures" map. I tried again to save the MWsnap picture and did notice the location where i should be saved. But it is saved somewhere in a hard to find place in my PC.
Possible the application data area.
My normal procedure is with Picasa3 running minimised.  ALT+Prtsc  to copy the active window to the clipboard.
Picasa then shows that the screen image is added to its collection
Then I open Picasa and export this picture to a map that can be found back.. Exporting gives the option to adjust the size of jpg compression for a website.
Usual the windows "My pictures"map   but Picasa  makes a sub map Picasa exports  there is no way to place the exported image direct in a selected map..

Then  use  the Blog edit insert image  and search exported image back at its location.

It is a bit complicated  insert image shows a row of sources from where an image can be copied. But not the clipboard?
Seams a logical source to me too.

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...

TS790 cat interface

A CAT interface  for the old TS790 144/432/1292 tranceiver to work with N1MM  including the internal CW keyer DTR and "PTT" RTS and WSJT MSHV with "PTT" control Using the 3€ FTDI USB serial interface picture bottom page first i bought the Kenwood USB serial interface cable that cable has the TS790 special 6 pin DIN plug this interface works well ...as long as you cut the 4-5  wire bridge on the ACC din.. with the wire bridge it did go offline after 30 seconds or so  Kenwood interface cable with CH330 eBay 15€    This type Kenwood interface cable uses a tiny 6 pin USB CH330 chip  The driver is CH340 known for Arduino it workes in W7/10 64  It has only TX RX Usart function no DTR RTS available  The TS790 settings are 4800b 8bit data 2 stop  default  N1MM does not list the TS790 it has the TS890  but that one does not support modes the TS2000 does support freq and modes and let you switch 2/70/23 it seem...
