"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat." AE

I can't believe its already 2012.  There's been some fantastic DX on 6M here in VK but just haven't heard any of here in my shack or been home at the right time.  Have a look at this map from the vklogger forums.

Also have be reading a little about AIS being used for a propagation tool and run across this receiver.

I operated the CQ WPX contest on the weekend of the 26th and 27th.  Much better propagation compared to last time on the higher bands.  I made 150 QSO's this time around with 12 on 10 meters.  For some reason 40M wasn't as good but 20M really came alive to Europe and I made a heap there.  My calculated score this time around was much better but I'll wait and see how it goes when I get the corrected score in a couple of months time.

Here's a short video of the band conditions on 20M.

The RD Contest is now done and dusted.  I wasn't able to operate all weekend but made about 90 contacts.  These where spread over 160M, 80M, 40M and 20M.  I put up my "random" wire for 160M supported by my ever trusty "squid poles".

A friend of mine gave me a Wilson 1000 mobile antenna recently.  It had been sitting in his shed for a number of years.  When installed on his car it worked a treat.  I tried it out and it didn't seem to be working.  I checked it with a multi meter and there seemed to be an open circuit.  I finally took it to work and some friends at a NDT company x-rayed it for me.

I received an email from the CQ WPX committee yesterday saying that my corrected score was available for viewing.  I logged in and found that I had 1 error and one call not in the log.  So my score ended up being 19173.  The run down of my score was very interesting.  It even showed the stations that incorrectly copied my call sign (which there was 2 of).  I also worked 40 countries.

I bought a FT-2800M a little while ago.  It's been the most difficult rig to program memories into.  I first though that I had a "dud" and it had a faulty cpu.  After some swearing and cursing I managed to program channels into it.  Thank god.  In the process I did find a technical supplament.

I paid my subscription to CQ magazine again.  I used to subscribe about 10 years ago.  My first edition (February) arrived while I was away.  Added to this I also ended up with a certificate from my participation in the CQ WPX.  I was stoked.  It's coming up at the end of the month so I'll be trying my hardest to improve on my score. 

Speaking of the WPX, it came around on the 27th and 28th.  I was hoping to improve on my previous score which I did.  I reached the claimed score of 40K which I was most pleased with.  At the start of the contest I had some problems with my R6000.  Its connected via my LDG auto tuner and it kept retuning.  After further inspection and connecting the MFJ antenna analyser I found that 10 and 15 meters had erratic swr.  I finally traced this to the 2 elements and the bracket that connects them to the main part of the antenna.

I submitted my log for the CQ WPX 2010 and the rundown was:

QSOs: 111, Pnts:390, Mlts: 103 and score 40170

The band run down was:

40M: 27 QSOs, 162 Pnts and 25 Mlts

20M: 60 QSOs, 172 Pnts and 56 Mlts

15M: 23 QSOs, 55 Pnts and 21 Mlts

10M 1 QSO, 1 Pnts and 1 Mlts

I finally got around to purchasing the CP610.  I have got as far as opening up the box. Hopefully the weather will improved so I can put it up.  I've also built a VK5DJ 2M Yagi but haven't built the balun yet. All in good time!

I finally finished the DK7ZB yagi on New Years Day.  There is some issues with the return loss which I have to investigate further but it seems to work and last night I had a couple of contacts to VK6 (about 2500km).  I also replaced the feedline with had some ingress of water even though I had sealed it with self amalgamating tape.  This time I used some FSJ4-50 which I had a length of.

I've been looking for/thinking about a dual band vertical for 10M and 6M FM.  Since most transceivers have these bands on the one antenna port it seemed like a logical idea to me.  Then along comes Diamond with the CP610.  I shall be purchasing one in the next couple of weeks.

Diamond CP610 6m/10M Antenna

My six meter antenna has been needing upgrading for a while now.  I built a 3 element yagi but it was very susceptible to nearby objects.  I'm currently using a Diamond HB9CV 2 element which works fine but is a bit low in the gain area.  So I will give DK7ZB designs a go and that's why I've been rummaging around for aluminium bits.

At the moment I have the boom cut and have some of the elements and am working on the DK7ZB match.  Next I need to make some sort of bracket/mounting arrangement for the Reflector and Directors as the design calls for  "on top of boom" mounting (I normally mount through the boom).  I want the antenna to be robust and well made so I'm taking my time!

Have a look at the SDR link, it's amazing.  I was listening to some HB9 stations having a QSO on 40M a couple of days ago.

I also managed to work the Victor E51CG, Paul A35A on 6M and ZL1IU on both 2M and 70CM (thanks all of you) !!!

I've been looking for the circuit of my FP-700 power supply for a long time.  I know I had one but just had difficulty finding it.  Looking through one of my draws today I finally found it.  I've scanned a copy and have both the full scan and a reduced size one here.

My QSL Card from Radio Praha arrived today!  Awesome!!!

Six meters is probably my favourite band but it can be so frustrating at times and today (22-11-09) was one of those days.  The vklogger map was covered in paint from spots, and do you think I could hear any of the DX?  Everything seemed to be bypassing me or VK3 altogether.  There's some stations active in the Pacific from South Cook Island (E51CG) and was hoping to hear them but no banana. It just amazes how it can bypass one area and not another.  I don't think I was the only person tearing their hair out but that's cold comfort.  I'll keep listening and hopefully I'll catch the right moment soon....

I've been working on a job that involved terminating and testing fire optic cables.  I've never done any terminating so it was interesting to watch.  The testing was fairly straight forward but having good test leads sure helps as does having fresh batteries in the test gear! 

Antenna connections are always a problem, especially when you don't have much room behind your rigs (and shack) and you need to connected and disconnect things quickly/frequently.  This monster is my solution.  I call it my Connection Matrix Mk1!

The CQ WW SSB DX Contest is coming up (24th October)!  I'm really looking forward to it.  No sunspots though (19-10-09)  It's going to be hard slog like last time but I thoroughly enjoyed the CQ WPX.  I've installed a dipole for 20M to see if it helps in anyway.  Also recently 20M has been full of "spewglies" and there's heaps of them around tonight.

I've just about prepared the shack for the contest.  I wired up a old footswitch that I got from work into the Heil mic adapter as I couldn't use any of the accessory connectors on the back of the FT-450.  The Packet connector mutes the mic so that didn't work.  I've setup my little Aldi Akoya Netbook for logging and VK Contest Log.  Good little program.  The Akoya is the quietest as far as RF hash goes, so that's why I use it.

----------

I submitted my log for the CQ WW and the rundown was:

QSOs: 100, Pnts:263, Zones: 37, Ctrys:43 and Score: 21040

The band run down was:

40M: 17 QSOs, 43 Pnts, 6 Zones and 5 Ctrys

20M: 33 QSOs, 80 Pnts, 17 Zones and 23 Ctrys

15M: 45 QSOs, 125 Pnts, 11 Zones and 11 Ctrys

10M 5 QSOs, 15 Pnts, 3 Zones and 4 Ctrys

I've been playing around with a Anritsu Spectrum Analyser over the past couple of days.  We are going to use it to do some testing of NextG mobile signals (just basic levels).  So I've been becoming familiar with it.  This sweep is from a Telstra Tower in Sale Victoria. I swept just the mobile phone spectrum.  The big spike with the marker over it turned out to be a broadcast link as I found out after talking to a friend.  The sweep below that is from a RAAF Radar. 

I did some Shortwave Listening for the first time in a long time today.  One runs across stations on the upper end of 40M but usually just tune past them.  Today I had a listen for a specific station, Radio Prague.  I download their podcasts and listen to them on my Ipod Touch but haven't as yet heard them, but today they had a thumping signal.  I wonder if those 2 sunspots had anything to do with it?  I also heard a number of RTTY stations about and when I checked, realised the CQ WW RTTY contest was on.  I also heard a number of SSB Contest exchanges but not sure what contest that was.  I also finally replaced the balun on the OCFD.  I purchased one from RippleTech so it'll be interesting to see how it goes.  Unfortunately the VSWR still was all over the place (I ran the Analyser over it).  It still seems to perform okay so I'll leave it for the time being.

I have been experimenting with the lower frequencies (1.8MHz and 136KHz).

I tested my collection of radios to see what they would perform like below 1.8MHz.  All of them have attenuation automatically switched in below this and it cant be switched off (without mods).  Apparently this is to protect the receiver from overload.  In the end I ended up using the FT-450 which seemed the best out of the bunch (FT-897, FT-857, IC-706MK2G and FT-817).  All these required quite large signal levels (100uV+) to do any good.  The FT-450 could hear ok from about 5uV.  I've also built a Mini-kits wideband preamp last night and it seems to be working ok.  It doesn't have any filtering so I did notice some (what I thought) broadcast signals appearing ever so weakly below 200KHz.  But overall it worked well and didn't introduce too much extra noise (It has a noise figure of approximately 2db).  My antenna is a random length long wire (approximately 60M in a "U" shape).

I also made some (105) contacts During the RD contest.  This included 160M, 80M, 40M and 20M.  Had no luck on 15M and 10M.  I was pleased as I had set a goal of 100 contacts.  Also the little FT-450 preformed very well especially on 40M which was very crowded. The IF DSP works really well.

I also ran across this nice looking rig.  I'm sure it should be in my shack!
