low SFI does not bother FT8 users...


 also FT8 heard and called  160m TI2CC    good low band propagation too  but only receive
As our Dutch soccer coach Van Gaal said: am I so good or are the others so bad  ;-)
In those days we had a great team but that is long ago. Now we have a woman EC champion soccer team . The gentle man are way over the hill.



 Well I tried CW   for  3C1L  160m  up 1
and VK9CZ 12M   CW  but  was not heard  the 12m antenna is a tuned  30/60/80 sloping 3 bandder
Even in FT8 mode 160m   Beverage rx  just a few N.A. do reply  like one way propagation.

lot of activity FT8 just a  few CW signals

70MHz IARU contest 19 20 Juli

 26 QSO in CW USB. Op zaterdag wat zwakke signalen uit Engeland, in de avond haast geen signalen meer. Dit was geen FT8 dat was duidelijk...  Op 70MHz is men in Engeland heel actief , voor een grote contest zoals deze IARU R1 24uur zoekt men daar goede locaties op zoals hier M0ICK/P IO84SA ik had QSO nr 4 Michael al 41! . Maar ook op de activity avonden op de Dinsdag avonden van de de maand zijn veel Engelse stations actief . Zo kon ik op de 2e dinsdag  van juni op 1 avond in een paar uur tijd 100QSO's op 70cm 432 MHz in CW USB hoofdzakelijk G's maar ook SM7 6 OZ SP OK DL   zoek  voor de agenda op : https://vhf-uhf.veron.nl/contesten/contestrobot/       Pas op Zondag later in de ochtend ging de band open eerst 9H1PA  daarna vrijwel heel Spanje ,het geduld werd beloond.  gemiddelde  haast 1200km  Ook EA op 70.200 in FM , helaas wel te dicht op USB waardoor een QSO haast niet mogelijk was.   4M station de IC7100 me...

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...
