WSPR DX

Last night 14  decodes of WD2XSH/17  best -14
Seems like every night different  challenges Murphy is around all the time.
Antenna current dropped to zero every now and then
with some relation to the higher voltage.
Basicly 3 things could be wrong: Antenna, cable or Variometer .
The last thing would be the worst but this Hagenuk Variometer is very professional build
Thick Litze coils  4mm  and all coated with a thick layer  epoxy.
 Culprit was old army RG213  PL259 brown isolation type
This is a short cable to the outside tuner.
I was using it for 160m also.
So this 475 TX is a good weak spot tester.
And the TX with IRFP4227 can survive even short circuit in the antenna.

                                                       Hagenuk



Had my best TX result last night  140W DC input
More stable and reliable using the IRFP4227
 first time decoded by N1BUG  twice
the relative antenna current indicator for  the first time was on 100%
with the IRF540 it was 50-60 as long as the FET holds..
Now the weakest spot is loss in  the air coils starting to smell.
It needs toroids  transformers or Litze wire.
When tuned good the IRFP stays almost cool .
And although  the loading transformer was changed fro 9:1 to 4:1  the  SWR over the 50Ohz short feedline to the tuning box does not go below 1:2
 resulting in 400V tt  = 142V effective  over 150? OHm
Tuning on  max  current in the line to ground does not happen at the lowest SWR point.


    this  explanes a lot the good signal of WD2XSH/17

printscreen dump to Dropbox  does a perfect compress. Dropbox pop keeps on whining about upgrading after the free file storage has been used.

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. Het...
