The early bird catches the worm.
 de morgenstond heeft goud in de mond.
Signals amazingly strong all the way from Clipperton.
I expected to maybe hear something but not signals like that.
This morning  before  QRL I had about 1 hour  just about matching the optimal time for Clipperton on the low bands.
 About 519  549 clear copy on the loop at 160
 It did not took many calls to confirm the QSO
not like my struggle on higher bands.

Then quick QSY to 80m 3533kHz   QSX up 2-5
Amazing strong signal at 80  579 clear copy and  fast operating.
Gaining receive time by skipping call and up EU non information tail after each contact. Just up says it all. I like that style. Very good operators they know to handle the EU pile very well.
 I am not only saying this because I made  it in the log.

The jammers  not awake yet, probably after a long night of jamming and annoying DX 

At 80m the pile was bigger after 30 minutes with my poor performing ?  vertical  i got trough.

S21XV   heard again  now at 7001 kHz  not strong good operator possible having bad local QRM.
This time jamming  made QSO impossible.

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…
