3B9FR 50.105 MH10 got'm



The activation  of  Rodrigues Island is the hot item for the  6  community.
After months of plane noise finally real DX .
A good signal and long opening after 3 previous ones passed empty.
Thanks to great activity of Robert and  antenna donated by UKSMG
 QSO time 15:39   a new one i  ! #212  and  MH  main-square  number 90
2 year and 1day  after 3B8DB

Heard long time over 1 hour in and out again heard at almost 17:00
 big pile with  DL OK OM YU etc etc many callers strong heard in the QSX
 50.105 3B9FR  MH10qh     QSX up 2 - 5 kc

When arriving home a quick look at the cluster showed that 3B9FR already had an opening into my area.. was I too late again 3rd day in a row (....)?
Pff  this time the signal came back in to about 569 good signal with big DL OK YU etc pile.

The month May seems to be the best for this area
The end of the TEP season combined with our starting ES.
looking in the list:
72 25-Mar-90 10:03 FR5 FR5EL REUNION isl 1 1
120 15-May-93 16:21 5R8 5R8DG MADAGASKAR 1
165 12-May-01 17:12 3B 3B6RF Agalega  HB9AGH 1
211 15-May-13 17:02 3B8 3B8DB Mauritius
       11-May-15 16:29 5R8UI   Madagaskar LH46DO  
212 14-May-15 15:39 3B9 3B9RF Rodrigues isl. MH10QH



there was more on the band like FR4NT worked 20km NW of me but not a beep
and later CE3SX was worked in ON  PA-close to ON
it really makes a big difference those 250km southwest!
G  EI-north  SM6 LA OZ  everywhere ..
CE is very rare to work at 50MHz  only 2 openings  in our area that i know of
20 August 2001  almost 14 years ago  19:19 CE3RR was worked
in 2013  CE  was worked in JO33 square too
The next possibility will be 2025 then  since we missed this one on the 14-May-2015
Why 6m signals always ( or never) arrive later and weaker here in my QTH?
Maybe the grass here absorbs more RF ..
One thing is changed since my early days in the 80-ties
More trees in a recreation area exists now but  more south of me and the nearest city is south SW.
I have tried several antenna's  9 ele 7 ele  2 el  now a 4 ele shared with HF   was not much difference in  signals on the terrestrial beacons  OZ7IGY LX0SIX 440km always hearable weak in flat conditions .
The only antenna I think that could make a bit a difference  is a stacked 2 x4 or 5 ele  having a bigger aperture then a single that i could try.
  
May is the month for this area

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 normal vertical mounting posit

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 cir

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. Het Rotor platform kan wel een meter hoger dat geeft meer  buislengte boven het zit nu op 3.5 meter van het
