AuroralE

All Northern Q-range beacons heard well last night 
Well almost all Arctic /B   not  heard VE8SIX FQ  that was heard long time ago  QRT?
only once heard VE4ARM EN09 via AuroralE  long time back


 50045.9  JW5SIX KQ26       529
50047.3   JW7SIX JQ58tb     559
50079    JX7SIX    IQ50RX   579

OH9SIX KP36 SM2 SM3 OH heard with Auroral T

50084 LA7QIA  KQ40   529 559  later to 579   only QSO that night

50106 OX3XR GP  weak
50100 VY0HL FP  hrd weak only about 10 seconds Q5  too weak to work

could I only get an antenna that gives 6-10dB more than the 2ele(7ele) I am using now..
I have not been able to build a bigger antenna that is really outperforming my tiny 3 bander.
 Last year I had the 7 ele LFA up  and was surprised  that the Steppir with 4  6m element showed about the same signal level on earth path beacons like LX0SIX with over 50m cable to the back of the house.
I was expecting a signal boost of say 6dB...  but that seems to be not possible.
So how to get 6-10dB more "gain" over the  2ele HB9CV class antenna??
I would not know. My last attempt with the YU7EF 7/8 ele was a disillusion.

Hallo Jaap, zo zie je wat bij de 1 werkt kan bij de ander wel helemaal niet werken. Ondanks alle mooie EZNEC optimalisatie. Omgeving is ook een heel grote factor. De steppIR stond bij jou misschien net gunstig m.b.t. 6m. Wie zal het zeggen? 73, Bas

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
