PACC 2020

Antenna's ready    Steppir   and new linear load rotary 40m dipole  14m  wide very light using glasfiber fishing rod's and foldback wire linear load design thanks Thomas PA1M

Using the  Hidaka Denki  driving element holder.
  replaced the trapped  multi band 40 20 15 10m elements with 2x 7m fishing poles that fits upon the 30mm center stubs filling the gap with tape also protecting the thin fiber rods against the stiff aluminium tubes.
This radiator is part of the 4ele VS2440  former produced by  Hidaka Denky
I can switch back to the original multi band the weight is very low about 1kg for an almost full size 40m rotating dipole not bad i think, it could even survive CIARA but i did not want to risk that.
The shunt wire is 2x 12.5 m foldeded back in one loop and about 1m wire  hanging down a the top, that this wire is moving in the wind does only slightly affect the tuning , the stray capacity does not change much.The whole 40m 7.000 to 7.200 can be  covered   SWR  below 1.5 
Tuning the antenna with this loop is not so easy. First test showed resonance at 6.8MHz
Then i cut 50cm each side of the vertical hanging wire and then the resonance jumped to 7.35 already. So it seems a precision job to tune it precise with the length of the topload wire
And it is.. i could not tune it after the storms 
First time it worked was a lucky shot ..
I changed the lineair loading loop using wire spreaders and the free hanging wire at the top is used to trim the resonance 1 m # 200kHz roughly , so cutting smal pieces 5 a 10cm and test again. 





PACC2 2020
I choose to run in the high power CW single section this time.
With moral support and company of Willem PD0OHW (photos) to experience the contest live..

But Tropical storm CIARA was expected to land about halfway the 24 hours in the early Sunday morning
So we had to decide to take the high 25m pole down at 05 hour before the high winds and rain would reach us.
That meaned  40m dipole 80 and 160m out...
And the Steppir at lowest position.

Saturday before contest start 15m was open     FT8 :   YB EU VK
I started  CW at 15m  but long CQ with no reply and no CW signals heard  i had to go down to 20m.
Not to speak of 10m  always start at the at the highest bandthat what the the hams  said before the age of FT8 and RBN  clusters internet. When one only could find out by listening the bands..

the week before there where some ES openings  but now CIARA depression seems blow away all
propagation...
Tuesday and  Monday propagation was recovered at 15  with many EU and PY at 10m...
That is how it goes.
Everyone had to deal with the poor propagation during this PACC
But i had high expectation for the Steppir  3 ele  for 15 and 10m ..
Only 20m was left  now but this 3 ele was working well and it seems lower in noise at least i can turn it with the back to the Solar Edge QRM of my neighbors home.

the low bands 160 80 where good to USA
even JA worked at 160
And remarkable good signals from USA at top-band  and 80
of those hams that joined our PACC contest thanks!
and not the WWRTTY ..
The good old CW nice to work

Goed gedaan Jaap, wat betreft die QRM....misschien is zo een x-phase kastje wat voor jou? Ik heb in phone nog wel wat gewerkt op 15m zaterdagmiddag. Maar hoorde van PA4O Peter al dat op CW niks terug kwam. Ik werkte zeker 100 minder QSO's vergeleken met voorgaande jaren door de slechte propagatie. Die 40m dipool klinkt erg interessant. Lineair loading spreekt me meer aan dan spoelen. Goed idee met dat 1 meter draad dat naar beneden hangt, dat geeft nog wat capacitieve load. Is misschien ook wel wat voor 60m. Waar heb jij die hengels vandaan? 73, Bas

Frits Kuiper Noorderhaven
7m 15€ p/s
Maar vandaag kreeg ik haar niet meer op 7 MHz
langere draad hogere afstemming zelfs na paar pogingen
lager dan 7.3 kreeg ik hem ineens niet meer
mogelijk maakt het veel uit hoe het draad van de lus loopt
Ik moest het eerst opgeven er moet iets fout zijn

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…
