ZF1AM 1854KhZ

Image
LSB ZF2AM heard very weak here early morning  Also PW0F was on topband  but not heard
better in south / east EU
 but precisely  1854kHz  is covered by some new s.m.Power? QRM I have direction west to direction the village at 1.2 km
The directivity of the Beverage is clearly seen on that QRM  it is almost gone when switched to East.
The QRM frequency is slightly moving around. It is about 5kHz wide only
Not able to find out yet where this new one is coming from.

Germanium diodes received from Mini in the box
1N34  and  1N60 type  150 pieces 4$ only received
 Tested  at 431MHz  with my EME UHF directional coupler
the BNC ports have calibrated attenuation I had 2 diode detectors one of them is broken.
Tried to repair by inserting an pin contact diode into the BNC but overheated the diode
is not easy to mount into a BNC connector.
 The diode still works but derated it gives 20% less detected Voltage.
That diode is unknown junkbox  type Ge -pin  showing "0" Pf  and 0.4V  barrie…

ARRLDX good timing

The ARRLDX had a very good timing

Today tuesday 28MHz is complete different no USA decodes for the first time in months.
no VK7 VK123    West Australia  VK6 was maximum DX "only"

last 24 hours  WSPR unique decodes  sorted on distance

ARRL DX CW

Image
In Category  Low power    mostly Search and P
propagation high bands very good on Sunday
How much longer can we enjoy this super 28MHz propagation ?
Even here in north-west were 28MHz signals are normally weaker at Sunday
BC WA MT OR came in well propagation was even better then in 2014 December ARRL10
Only missing State:   North Dakota , South Dakota, Nebraska
last year N and S Dakota worked within 1 minute ..

my goal:   6 banders    as many as possible
160m was the difficult band  17 QSO possible


Trying the ARRL CW this early  morning at 160
I could not use N1MM plus  the USA call all greyed out
and  logging had to be forced as invalid contact
must be simple  a setting  or country list still at PACC  but I could not fix this yet
But still N1MM score is 0 with 940 invalid contacts after loading wl_cty

ack to N1MM clasic

already sunrise I was late.
Few 160 W/V signals heard  W3LPL did not hear me Saturday morning bad sign for top band.
4 QSO only   (low power)  in the end 17Q in …

TI9/3Z9DX Top band

In the run up for the ARRLCW  this weekend some interesting activity heard at top band .
06:00  At SR heard TI9/3Z9DX  only short in workable strength 1845kHz  working SP
Before I could call  they went QSY to 40m phone

7150 LSB  was S5-6

Early Friday morning TI9/3Z9DX too weak also having rattle QRM direction west again

TI5/W9RE     much stronger
HC2AO  good signal today  easy to contact
 weaker then HC2PF but hearing well

After topband TI9/3Z9DX   qsy to phone  at 7155 QSX 7170kHz
of course lot of D-QRM
And OT4A  at 7153 to stubborne to  move  just kept on CQ DX-ing
it was "his" frequency   of course  cursed by a lot of om's
Very good rig 4 ele  17m boom    up  and down by motor control
Only thing Theo is missing is a tuning control on the rig.
Just moving few kc down would be the smooth solution in line with code of conduct.

Arduino NANO controller belevenissen

Image
De Arduino NANO met LCD voor een SWR/POWER meter  in test opstelling. De software van ON7EQ  geladen en werkend, maar voor het zover was moest ik aardig aan de bak. 

Ik had van Arduino eerst al de iets grotere UNO met Keyboard LCD shield Daarop heb ik de SWR/Power meter software van Jean-Jacques ON7EQ geinstalleerd Heel mooi spul Arduino echter aansluiten op de PC via USB kan nogal moeizaam gaan. Arduno heeft FTDI techniek en ook drivers daar heb ik goede ervaring mee, waarom het met Arduino zo moeizaam gaat is een raadsel. PenP installeert een standaard Usb-serial driver  CH340 op mijn PC voor de UNO werkt die niet het moet in de HW list zijn:  aduino UNO(comX)  De door Windows gekozen driver moet handmatig worden ge -update volgens deze procedure  met USB aangesloten UNO: Winkey+break  apparaatbeheer onder poorten zoeken naar de usb serialport die de UNO heeft toegevoegd  rmk  stuurprogramma bijwerken  >    op mijn computer zoeken > ik wil kiezen uit een lijst > browse naa…

160m dx

Image
good propagation this morning  05 UTC   testing the E-W Beverage
HC2PF      579 op Beverage
HC2OA     549
P40L          589  op Bev    backside 559            599 op TX ant    easy 100W
Beverage E-W  so it works   switching gave 2-3 S units difference
 direction 270dgs 450m  ex army telephone wire un-twined 2 separate wires
3 steel 4 copper wires   20 Ohms / 450m
  it has to follow the ditches unfortunately I can not choose N-W
 to the right is the church tower of Zuidwolde at 1500m

box at near end  ( to W0btu )
but with this morning fb propagation and low noise  I can hear them on TX antenna too

hc2pf_160_bev.mp3?dl=0
P40l_160_bev.mp3


K1N toch  op wat banden in het log de laatste dagen was het niet zo moeilijk de meest hinderlijke LIDs waren al geweest en de DQRM vind het ook niet meer zo interessant
 op 20 en 10 met slechts een paar calls

PACC 2015 CW low

Image
the PACC 2015 is history
Many thanks to all PACC friends for the competition and points.

High band propagation was good  low band poor.

Again in the low power CW section
 K3  100W  40/20/15/10 rotatable dipole 22m
 verticals  80 and 160

no beam set up  it is still grounded
 I offered my PA competitors a good opportunity to get me of  1rst rang this way..


Bruto resultaat 2015     1458 QSO  267 multy    389019cpunten



Alweer in de categorie 100W  all band CW.
Zelfde antennes dipool en vertical's
Ik geef de concurrentie toch alle kansen om me nu eens van de 1e plek te krijgen..
De beam heb ik nog steeds niet weer omhoog.

De 40m antenne moest nog gerepareerd  SGV springers door oxidatie. Mijn O/W Beverage bi-directioneel werkt helaas nog niet beter dan de K9AY loop.
De richting is niet optimaal voor USA/JA maar word bepaald door de richting van de sloten en die lopen hier allemaal oost-west De K9AY  daar zat plotseling een onderbreking in de kabel. In de  richting Z-O waar de om-schak…

28MHz super propagation 1 day WSPR

PACC uitslag 1974 ...

Image
Het kan erg veel minder met de propagatie getuige dit 40jaar oude PACC verslag 1x W op 20m ! ...klaagde toen ook al... 




Vanmorgen op 160  weinig ruis op de  verticaal mijn Beverage is gebroken.
Heel goed signaal van HC1PF  onder de blind callers voor K1N6kc lager
Zonder te luisteren tunen of zenden dat is heel gewoon tegenwoordig.
Maar wat is de propagatie toch goed vergeleken met b.v. de jaren 70

K1N

Image
Saturday early morning K1N 1817.4   strong! to 589 big signal for 160.
That should be an easy one call QSO..  hahah I did not knew then that I better went back to sleep...
k1n_160_1.mp3

One time responded PA0 but never received my full call then they went on with an Italian.
Hard to understand that with such signal I could not make it.
I used to have a decent 160m signal even with low power and thought it be easy with such signal. Should have known better eorking DXpeditions with the QRP ACOM1000 is very hard..
They will have heavy QRM s9+  I guess
It is like EME working DX-peditions  the path attenuation must be about the same and the QRM does the rest.
after some hours of trying I finally  conclude   it is a mission impossible  for my humble station.
And I better just keep sleeping next time.


K1N 1826.3 heard well max 529 or so not strong enough to copy me
no clear greyline peak  best time 05UTC 05:30 here
