Me at the remote station.

Thursday, 6 October 2016

Going to be the gorrilla pop up station at RSGB Convention.

Here I was testing it in the pub last night speaking to M1ACB and G7SOZ.

The station REAL RF end is at G3PJT QTH.

K3, KPA500 (if turned on) and decent antennas, including a rotator.

The station was put together by G3PJT, G7VJR and a host of others.
Go to Bob G3PJT and Michael's G7VJR presentations at RSGB Convention for more info or come find me about the place.

Clublog and LoTW ADi files

Just uploaded as many of the adi files I could find for previous operations to clublog and lotw.

This will have added these qso:
M1KTA            978    
MO1KTA          0
MQ1KTA          0
3B8/M1KTA     803    
C5/M1KTA       1,258    
CT7/M1KTA     7    
DL/M1KTA/P    0    
F/M1KTA/P      0
ON/M1KTA      0    
HB0/M1KTA/P 0    
HB9/M1KTA    0    
KH6/M1KTA    0    
KH8/M1KTA    393
W1/M1KTA      0
W5/M1KTA      0    
M1K               207    
M1KTA/6W     1,819    
OZ/M1KTA/P   14    
SD7B              575    
SM7/M1KTA    0    
SM7/M1KTA/P 438
VEn                 0

There will still be loads (IOTA mostly) that have never been computerised.

Since about 2011 I have NOT sent physical QSL card to 100% of all QSO made on trips but have chosen to wait for QSL requests after having had many 3B8 cards from 2008 returned.

clublog OQRS means that I will get quite a few requests for QSL cards, that might not have been sent before.

40m 4 sq on EU-011 what happened?

Was asked to post about what happened ...

It is one thing to be able to do running repairs or modifications when in home shack, it is completely different if you are on a remote island and you only have what you have.

The 4 ground screws arrived fine (actually the station used 8 others for the other antennas as well).
The 4 traveller 10m poles (one borrowed from Gavin MM1BXF) all were fine.
The 4 40m gp's with feed plates and 8 radials each were all fine (tuned to 7.150 100Hz above where I wanted the 4 sq to be)
The 4 75 ohm feeds from the phasing box to the 4 GP using F type connectors were fine.
The control box was fine.

The site where the antenna should have been put up moved!

The line from the operating position to the phasing box was not working. Grrrr (putting it politely)

The relays were NOT latching which meant to maintain a set of phasing the relays had to remain energised. In theory you could select a direction and it would all remain but then after a time one or more would switch and the vswr etc all went to pot.

At home the separation was 30m at most and the length of control cable I used was fine. All power (12V) coming from the shack end.

On EU-011 the separation was closer to 95m so the original cable would not work.... the substituted one should have been stranded CAT5 and all copper conductors, I find it was NOT but solid and was copper flash coated steel and the voltage drop was not only horrendous but was not equal over the different cables. I even tried 2 PP3 batteries to raise the voltage to 18V and even 4 in series/parallel but it was just not stable. I even tried a bodge with some coax and a wire.

As the IOTA contest time advanced closer I had some hard choices to make....

One option was put the thing up as intended and set the default location towards UK and either run out (unsafe at 2am) and switch the direction. Or do what I did in the end....

Sacrifice the coax from the 17m VDA I took and use this to create a manual 2 el 40m array with one element phased such that I had directivity in line with the elements (ish) towards UK. This also meant take down 2 elements and remove the radials (I added them to the 40m ones already up). I think the 40m signal was fine and managed QSO and the SDR RX looked FB too.

 The signal might have been better had I had all 4 up but was very annoyed and I did not have time to go through putting up the 40m array after I found out the problem which would have meant moving it so the original cable worked as that would have meant moving everything which already worked all over and not using the empty fields I had available.

It was a DXpedition and you live and learn.

E51KTA Update

I can confirm dates...

E51KTA should be QRV 10th March to 19th March 2017.

Can only promise BERU w/e on S Cook dunno exactly where I will be after
that maybe N Cook maybe not... best listen on air.

This came from work from JN1GLB and F5VHN I am sure I might add to it...

I am sure I will model this in various configurations, including putting the whole thing through 90 degrees and mounting it on a pole above the sea. It then becomes a series of nested vertical 2el that is steerable.
