super tropo Saturday evening 23cm


Saturday afternoon my 23cm system was up back in the mast
The transverter is direct at the feeder of the dish.
The new 23cm LNA with the SKY67151 and 23cm 100MHz wide bandfilter
Made by VHF-design  real fb product.
is replacing the SPF5189Z  good and cheap but wide band 0-4G no filter
It seems that the 23cm receiver need a bandpass to keep all the 4G and other high level signals out
how about 5G when it is real in operation if that ever happens since using high 4G and 5G field strength in urban area's is controversial. 
\
new LNA
Left top is the feed connection the SMA relais
I had to replace some N and SMA pieces that caused loss and high SWR  about 35W direct at the dish. 

PA0V  helped me,  my foot injury make me still unable to go.
We where curious about the performance of the  SKY LNA.
And if it's bandpass filter could stop the 4G breakthrough QRM.

Coincident or not, the antenna was up and  there was real exceptional good tropo happening. for this time of the year very special. iT happend to be only in the north part of PA-land.
   
As if this LNA was  magic ...
 1296MHz  beacons all far above normal.
The normal "local"beacons
OZ7IGY GB3MHZ PI7ALK ON0TB DB0GW PI6ASD DB0XY DB0VC DB0LTG way over s9....

1296800 SK6MHI  S7 SK7UHI S5

Then a new one SK4BX/B JO79LI 1296.950  850km never heard before. S3 but this was a land path! SK5EW was listening but his location was not as high as BX/B no QSO sorry enough
SK4 is rare at 23cm here

 LA1UHG 1296860   
SR1KOL   1296957  JO74 TO s7

  Easy cw QSO with SP4MPB KO03HT CW  900km

Only a few hams QRV . 
FT8 did not yet arrive at UHF as it is on the lower bands.
  
LA4YGA and DG1BHA JO73 used FT8
 and SP4MPB received my FT8 but not yet ready to tx

I think FT8 could help to generate a lot more action at 23cm
Now one has to use KST2ME  to find QSO partners and their "home" frequencies.
With FT8 at least the frequency search is over.
Left is antenna direction and TX/RX  period 
The weaker signals too weak for CW / phone no problem in FT8
Then to west , heard GB3USK IO81VC
no G heard cq FT8 /CW did not wake up anyone
and then a 59 carrier 1296985 
OY6BEC IP62MB 1267km
 real S9!!

 https://youtu.be/268k4oLaY9A


 All night until 01 local OY6BEC was still strong
and even heard at a vertical omni antenna nearby

Very special propagation in end November. 

 But now Sunday evening propagation is flat again
The local beacons seem to be a better copy
ON0TB  now moved to 1296933 JO30BM i hear it constantly
No more cracking QRM in S-E and other directions where 4G
GSM transmitters 900MHz are very strong
The band pass filter workes 
so this SKY LNA is a great improvement. 
Professional build and absolute stable as claimed.

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...
