JT65

several JA decoded this morning in JT65    signals too weak for FT8


WSJT-X V1.8 first tests

Sunday AURORA 70MHz  recording GM4ZUK/P
http://www.qsl.net/pa0oos/2017/GM4ZUK_4MAU.mp3

Installed the latest WSJT-X V.1.8.rc1 beta version

on a W7 32b DELL D420 notebook

It crashed few seconds  after start  several times  need to force stop with p.m.

After rebooting PC it was ok with CAT to the K3

In between i started V1.6 again
Frequency settings of  V1.6  where lost and needed reset to default.
these setting are removed by V1.8  and vice versa.

Then i had the first FT8 mode contacts  LX1JX groundwave dial 50.313
only ground wave with some MS enhanced scatter are possible in the present propagation dip.

The frequency dial settings are depending to the selected  region  ,  1 2 3 or all
They are different to   version 1.6        WSPR 50.293  JT65 50.276
Set to Region1  was  USB 50.310 as default JT65 not 276
in the band selection list box there are 3 6m entries when  regions "all"  is selected
the first is the usual 50.276
80m WSPR no spots freq. must be modified 3.592600  it …

IC706 classic repair

Image
IC706 classic  was damaged by high RF at 144 input I use this old but very good rig as 146-148  i.f for 1296MHz  XVTR Receiving Graves at 143.050  pings and scatter i forgot to disconnect the VHF antenna   ( 3 band 6,4,2) when transmitting at 6m with the 7 el just underneath so it became very quiet at 23 / 144.. 144-148 /VHF input circuit part with 3-PIN antenna switch  and MA862 band switch that switches between 2 input filters. TOP = 60-200 MHz  down is 144-148 bandpass preselection in front of the    uPC1658G  wide band preamp


MA862  bandswitch fried by high 50MHz signal at 144 /VHF input SO239

replaced by 2 BA891 bandswitch diodes Ebay 


above temporary jumper to select 144-148 band pass filter without the bandswitch diodes the IC706 does not switch to the VHF filter when tuning outside the 144-148 range  a solution without bandswitch But the burned out  MA862 protected the IC706 preamp against further serious damage So it is better to have  bandswitch diodes placed there 4 pole t…

50MHz wijd open typisch ná het weekeind

very good 6m opening Monday 3 Juli 2017

many DX heard sorry not all heard DX resulted in 2-way because of  JT65 slow QSO rate
Briefly  check of CW part but no promising sounding signals.

wsjt log to search your decode

( 6m)  dx rules:
1 best DX is not during weekend's
2 good openings never repeat next day

Als vanouds ná weekend  op maandag ochtend 6M band  open  voor DX Japan Korea China
in het weekend was het dacht ik niet veel soeps.

Antenne moet toch wel echt op QTF 030 voor JA
Korea 3 stations  veel JA   China 2 stations , de 1e keer dat ik hier zelf China op het scherm zie.
Nu lukte het met BA4SI   al vaak super zacht in CW gehoord  nu met JT65  wel.

Heel vroeg open 07 UTC al eerder deze week heel vroeg rond 05 UTC  diverse USA gezien
raar tijdstip voor USA  beste was Alabama en KC0  in EM25   ander  pad moeten zijn
lange pad kan toch niet vanuit noord Nederland?


Druk met 23cm  reparatie alweer vocht in de voeding boven.

144MHz ES 26 June 2017

Monday 26 June   A remarkable day!

Noticed cluster spot's   DL  reporting  TA1D/3  144.300

I switched on the old FT225RD  ( 30W USB 20W CW/FM)
antenna  DK7ZB 223  ( 2e 4m / 6m  3e 2m  mini antenna  f.b!)

After some time listening  some DL's calling at 144.300
And sudden woow TA1D/3  calling cq  Kadri from KM39BP  West Turkye coast
 In and out  i called several times  then signal became stronger S7 and QSO
woow  Turkye on 2m  never heard before even not in the golden ES years  of the 90's

audio recording TA1D/3

Monday band was very quiet few hams only no big pile Working hams could not be QRV
Sorry for the working class this type of special DX occasions always seem to happen outside the weekends.  In the past  the interesting DX at 6m allway happens at working days.
 2/7 * 100%  30% would be the weekend chance by calculation
Evening times are not as good for real dx or it must be afternoon just before dinner time
normally duri…

IARU 50MHz 17 18 June

Saturday morning new constructed 7ele 9m3 boom V-dipole radiator was placed in the mast at 22m a.g.   Replacing the HF + 5e combi

After frustrating experience with JT5DX
14 June 16UTC CW 519 1 hour copied cqcqcq
called 100+ times no response
Time for another attempt to improve the 6m set-up


Band was closed Saturday morning  even quiet at the JT65 276 !
It looked like it's gone be a contest type propagation weekend but....
In afternoon right from start huge activity strong ES signals  all Saturday.
Mostly EU  but also  PJ4NX  and PJ7/W9DR


Saturday even small pile ups   SP OK UA I S5 9A
very short skips  IO80  600km   EI SP OK
We where again in the middle of the reflection cloud
203 QSO first day   added only 70 on Sunday
Sonday Es signals still strong but hard to find new ones.
We just do not have a lot of customers at ES distance from  our QTH
East EU could tank G's and DL
The E skip from G land lands in more ham / contest populated area's it seems
Relative high QSO num…

N1MM LOTW

I do not know how it happend but i got one log record with empty call sign field
This was reported by TQSL when trying to upload my log to LOTW

N1MM can not remove a record with empty call field i found out.
Deleting that record is normally confirmed by N1MM
But the faulty QSO record does not remove.
Here 3 PC's  in the network running N1MM  PC3 has IC706  + XVTR  23cm
PC2  is running WSJT / WSPR with the K3 or logging N1MM
PC1 the fastest Laptop is for contest use
All PC's have N1MM  and TQSL /LOTW
Deleting a QSO that is logged by an other PC in the network is not allowed that makes sense.
To delete that record I filled in a fantasy call DE1LET   and then it can be deleted for real.
You would think:
So what, let TQSL ignore the empty record,  just update it.
That's what i did
But  when checking in LOTW  QSO's where missing just after the "empty"field
 that happened to be my season best DX of course

7 8 June 2017 huge ES

June 7 2017  super ES propagation  not  favoring  my QTH as usual
 JO33HG in the middle  in the eye of the ES  dx happens over my head

 17:23Z  144.300 HA8HI CQ ES 59 one time loud  but gone  ms / es
 17:32     144.300   YO3FAI  heard several times CQ

70MHz  YO HA OM OH  DL

 later 50MHz   KP4 FG    some USA  but here just a few
no reply to cq
 USA signals far better to HA OK etc  not here
Only a few crumbles of the DX  could be copied here
possible my 5 ele  is not good enough?

Most DX heard only very few QSO
ES DX if it  comes it comes in waves signals can be gone a minute later.

June 8
evening  short open to West USA
17:47 WA6OSX CM97 -10  R-06  working DL
17:51  N6ML      CM97eq       -13  working  DL

The morning very open to JA
50.276 JT65  lot of JA  heard
 just a few 2-way due volatile signals  most calls only seen once and gone
 To improve 2-way QSO   replay with report to CQ  will help

june VHF UHF SHF contest

Image
Alleen 23cm  meegedaan

22 QSO  na vele uren
Veel activiteit in EU in deze grote contest. In Nederland slechts 2 stations op 23 !
Deze contest is blijkbaar onbekend.
Zonder ON4KST  is het maken van verbindingen  op 23cm haast uitgesloten.


VHF UHF velddag  contesthelaas net 2 dagen te laat na de goede  tropo op 23cm  nu zeer matige propagatie overal in W-EU  veel regen  in Groningen prachtig weer.

Opvallend in Nederland doet slechts een enkeling mee aan deze contest
Niemand heeft er blijkbaar interesse om verbindingen te maken op 23cm
De SG labs 23cm transverters zullen wel voor de heb aangeschaft zijn?
In Nederland met wilde regelgeving is het ook moeilijk gemaakt om antennes te plaatsen.
Alles moet kunnen maar niets mag.

Het signaal van PI4GN  ontbrak nu  op expeditie F4VSG/p  in JN39FL
Veel regen daar,  ik hoorde ze zaterdag gelijk redelijk maar ik moest QRT
Later op zaterdag avond  De antenne rotor in JN39FL met stop op noord

JT65 opening to JA

6m seemed  dead when  i came at the radio  early  06\\\\\\\utc  but  i saw JA was worked  from JO32  here at first  nada JA
Then 07:20  UTC sudden band opened  here too with JE6KEA  -20  first call decoded
then a lot JA  signals  JE6HJT     -13 JI4UEN     -11 JA6TEW   -11  JN4MIV    -17 JE6KEA    -13      JH4MGU   -12  JI4UEN    -12  JH4IFF    -10  JH3VJV   -9 JA9AVA     -2  JF2WXS  -18 JA5FJJ      -22
JA3EGE    -21  PM74
JR2WYD   -12       PM84   JN1JFC     -3    QM06   
relative few 2-way contacts resulting  because of the fast QSB JT65 is a magic mode  but the slow  exchange cycle of 1 minute kills most QSO's 1 minute cycle  is too slow for the  deep QSB on the fragile JA signals Responding to CQ  without report takes an extra 1 minute exchange  that was too long for most
JA calls that replied. 
Started to be more active with JT65  a lot of interesting DX  seems only to be in JT65
JT65  50MHz  50.274 shows huge activity  and real interesting DX  that is not easy heard in class…

JA9IPF 6m JT65

Image
Grumbling can help ..just when I wanted typing:  I can't hear any serious DX here.

I see JA9IPF -5! replying for  PE1HXK    the first time  Japan in JT65  on the screen
I called CQ  low in the window 800Hz   i saw Henk did not reply to JA9IPF

DX exception to JA   JA9IPF and JA9AVA heard in QSO with JT1CS  and faded
opening was too short for more  i did not call CQ earlier i lost faith for DX...
Normally DX is not reaching JO33hg


so if grumbling helps i try again...

why can i never ever hear a BY BV3PU  or JT1CS here
 like G4FUF can, as long i have been on 6m G4FUF seems to hear and work every DX I can only dream of.
 Building a better antenna? I tried several longer beams including the quiet LFA   but it never seems to make much difference
The ground wave beacons are weak and stay weak 
no matter how much aluminium was up in the mast.
And why at  prime rare DX time , "local" ground wave ham's keep responding a cq DX?
sure i like to reply any calls but please do not waste va…

50 MHz JT65

Just when I was typing
I see JA9IPF  replying for Henk PE1HXK !   the first time  i see Japan in JT65
exception to JA  only JA9IPF and JA9AVA heard but AVA was in QSO with JT1CS  and faded




All day 6m is open to JA BY BV from S-EU if i see all decodes passing.
Until now here only single hop ES and rare double hop to 4X 5B
I am still hoping for  some Asia
psk reporter does no longer update my decodes  but that does not surprises me it is software and it is network.
When it works it is a great site amazing DX  going on in the JT65 world

lot of activity at  50.276  USB dial  JT65

Interesting to see what DX is possible  just a few 100 km south / east

today  saw HS0ZIO  was worked and  YI1SAL LM23ei
and JA  's DU  ZS1  reported  in s/e EU  EA8 I SV
I can not remember that HS was ever worked at 50 MHz in cycle 22 23 24 ?

 here in JO33hg as usual  i  see what goodies  others can hear

Today 4Z5ML worked and 4X6AG heard

Best dx this week is A45XR  JT65

6m is not as closed as it would be w…

CQ WPX CW N1MM update 27May issue

Very high QSO numbers
Propagation very poor 10m 15m complete closed   no ES 6m and 10m
Weakest 40m USA signals since ages  just marginal signals of the big guns
The WPX is no dx contest maybe that is a good thing for the near future..
few dx  40m  ZL4YL CX9AU  could not  QRP 100W
live is to short for QRP

N1MM trouble after update 27 May
CAT problems with K3 not possible to tune down to CW part
The K3 jumped to wild frequency's  95 MHz
had to go back to the previous 24 May version no problem with V 1.0.6347.0
