IARU contest QRP/QRPp event

The IARU 2012 contest has come and gone it was not without atmospheric grumblings. High solar wind at times over 700, Kp index topping out at 6 and this being the aftermath of the class X flare last week. On a brighter note (no pun intended)  the sunspot numbers are up along with the flux readings.

 So how did all this solar mumbo jumbo affect the contesting goals at VE3WDM?? My first goal and last goal of having fun and enjoying the contest was accomplished. As for adding to my DXCC count I only was able to grab one DXCC. The spotting networks were alive with South Pacific and Asia but at VE3WDM nothing at all was heard. My openings seemed to be centered around Europe with the occasional South American tease.

 This contest for me was not about gathering points and contacts. It was taking advantage of a large amount DX and working them with the least amount of power as possible. This meant the contest was slow going and not worrying about total contacts and points. 99% of my contacts were made with QRPp power and some with QRP. Each potential contact started with trying to make the contact with as little as 50Mw's. I had to stop at 50Mw's as my LP100A meter will not measure any lower power output. Back when I ordered and built this meter I never thought I would ever be operating as low as 50Mw's......my thinking was "an attic dipole antenna at QRP of 5 watts I am pushing it" funny how things change over time. I have a device on order that will allow me to measure power output into the nano watts...not that I will ever go there......but you never know!! I was not able to top my all time miles per watt high of  45,868 well maybe next time.

The setup the above was done with is the Elecraft K3, LP100A power meter, Hendricks 41dB step attenuator and the DX-EE dipole in the attic of a 2 story home in a "Z" configuration.

Hendricks 41dB attenuator built and added to the mix

Hendricks attenuator in service
It's Friday and the IARU contest is tomorrow, I had been checking out the propagation throughout the week and things seem to be calming down. Well until yesterday afternoon and the sun released an X1.4 solar flare and if that was not enough a CME as well..... Oh did I mention the CME is headed in our direction as well. So far the solar-terrestrial data seems to be ok. What's not to bad about a proportional hiccup is that it affects all of us, not saying that is a good thing but in the contest  the playing field stays level. This past week my Hendricks 41dB attenuator came in. The assembly was straight forward and was done in no time it
Final testing
tested out ok and I was ready to start using it. The attenuator has to go in series with my antenna  I placed it in series with my antenna B port on the K3. Both feeds from the K3 (antenna A port and B port) go to a LDG DTS-4 switch. Here I am able to place the dipole antenna in series with either antenna Port A or B. I did this as I can set up the K3 to have different settings (power output, filter selections, ATU on or off... etc) for each antenna port. So I select either antenna A or B on the K3 and then on the DTS-4 I select either attenuator in or out.

Now when I want to use the attenuator it's a matter of selecting antenna B on the K3 and Ant B selected on the DTS-4 and I am ready to go with all the setting on the K3 done.
My goals for the IARU conest
  1. Have fun and enjoy!!
  2. Look for DXCC's I do not have so I can add to my  ARRL Diamond  count.
  3. See if I can beat my miles per watt record of 45,868 miles.
  4. Have fun and enjoy!!
Some of the extra parts
Back to the Hendricks attenuator for a moment..........the kit did come with some extra resistors and switch also the hookup wire was missing.  I also noticed that the color code for one of the resistors had a misprint in the manual. I emailed all this information to Hendricks last week and up to this point I have heard nothing. Also I did have what I thought to be a problem I emailed Hendricks about it. Their reply was "I don't know" and that was it!! Well I figured out the problem on my own but this being my first kit from Hendricks I was not impressed. Maybe this is just a one off many of you out there have had kits from this company what has been your experience?




Now THAT was fun!

I participated in the QRP-ARCI Summer Homebrew Sprint for only a very little this afternoon.  But thankfully, quality is not defined by quantity, so the QSOs, while few in number were great in fun.

I began by operating on 20 Meters.  The Buddistick was set up with two 11 inch arms, the coil and the super long whip atop the Jeep on the magmount.  With my coil tapped in the normal 20 Meter spot that I am accustomed to, the Autek analyser displayed an SWR of 1.4:1.  I hit the ATU button anyway, for a very short “Brrrrp” and got a 1:1 match.

While on 20 Meters, as I was calling “CQ QRP” for a bit, and much to my surprise I was answered by Fred G4HOM out of Birmingham, England.  He was much louder than the stateside stations that I was working; so I immediately thought “tower and beam”. Nope!  Fred was using his K2 at 10 Watts to a simple wire – propagation, being what it was, favored a QSO between Lake George and Birmingham.  Signal reports were good both ways.

Shortly thereafter, I switched to 40 Meters by undoing the tap from the coil to take advantage of the entire Buddistick coil, and I added two more 11 inch arms.  After a bit of a scare that I won’t go into here (due to my own stupidity), the KX3 had matched the Buddistick to 1.4:1 on 40 Meters. I had several QSOs down around 7.030 MHz, including one with my very good friend Bob, W3BBO.  This was our first QSO while I have been at Lake George.  He had a good 579 signal and gave me a good report as well.

The Buddistick on the magmount, using the vehicle as a ground plane is great combination.  Thanks to W3BBO for getting me to try that.  It works so well that I may just forego using the EFHW wires unless I am on the hiking trail later this week.

Oh, I don’t remember if I mentioned this; but I decided to leave the Lead Acid battery home.  I am going strictly with the Lithium Ion this week.  It held up very well this afternoon.  I never dropped from 5 Watts output throughout the couple of hours of operating time this afternoon, including a few prolonged “CQ QRP” sessions.  I think “The Little Blue Guy” will be quite adequate for my needs.

QRP-ARCI Homebrew Sprint tonight

Well, this afternoon and tonight. It starts at 4:00 PM Eastern and lasts until 8:00 PM. And this will be the first big test of the KX3 in the portable environment.

We are up here at the Lake (George); and what a difference location makes. When we got here, I called my friend who is staying at our house and is dog sitting for us. He told me that back in South Plainfield, it was 102F (39C). Up here at the lake, it was a beautiful 78F (26C).

So the plan for today will be to operate from right near the cabin. I think I will go with the Buddistick attached to the magmount using the Jeep as the ground plane. That arrangement has worked well in the past. I will probably stick to 20 and 40 Meters; but may also give 15 Meters a try. According to the latest solar-terrestrial chart, 15 Meters should be in good condition today.

I brought the Autek antenna analyzer along to help quicken the process of setting up the Buddisitck. Thinking about it, I probably could have left it home. Using the Buddistick on the magmount is actually quite easy to set up. All I really have to do is set up the “standard” configuration, set the tap on the coil for loudest receive noise and let the KX3’s auto tuner handle the rest. The analyzer comes in real handy when setting the BStick up in the field and for dealing with finding the best length for the counterpoise wire.

So hopefully, i will hear some of you on the bands later today. Please give a listen for ol’ W2LJ.

FOBB 2012 News

Today I received the following e-mail from Bill W4ZV:

“Hi Larry, FYI on the WRO live blog Richard KI6SN just confirmed that he will be doing FOBB this year and promises results within 2 weeks. Said he would be making an announcement on QRP-L next week. Great news! 73, Bill W4ZV”

End

OK – that’s all  the news I have.  I have not received any answers to my inquiries about FOBB, so I would suggest you keep your eyes peeled on QRP-L for the next couple of weeks.  I do not know if FOBB numbers will be issued; or who will be doing the issuing.

This is a great event, and I’m glad to see that it’s not going the way of the Dodo.

LHS Episode #083: Smokey & The First Lady

Welcome to the 83rdest episode of Linux in the Ham Shack. Freshly back from the Dayton Hamvention, Russ jumps in by telling everyone his experience at the show this year. The short version: It was great! From there, things move on to a question of FCC rules, at least in the mind of one ham.

One of the topics that kept repeating at Hamvention was: What is a good contest logger for Linux? Up until recently, it was hard to think of one. The ncurses-based application yfktest is out there, but thanks to IZ3NVR, our hosts discuss a new option. Tune in to find out what. There’s also some feedback, occasional rambling and hardcore lunacy. Everything you’ve come to expect from an episode of LHS.

45,868 miles with an attic antenna……SHUT UP!!!

The K3 is ready to go at 100mW's
Well as many posts have mentioned the CQ WPX CW contest is now history for 2012. There is no total score, multiplier count or a prefix total to brag about here. This contest I was hunting DXCC's. When the hunt slowed down ( and it did for long periods of time) I then worked stations with as little power that my Elecraft K3 could muster to see if I could make contact. I was able to add 6 more DXCC's to my count (at 5 watts QRP) but I must admit at the start of the contest I was hoping to score around 15 or so. Oh well it seems that I have at this point most of the popular entities. I found conditions to Europe to be great but the South Pacific areas were dead up this way. There was more of Africa this year but the pile ups were huge at times.
To make things interesting as I was not "contesting" in the true sense I started to drop my power as I gave out contest points. I started at 1.5 watts to CR1X in Finland that worked out to 2755 miles per watt. Update....Thanks to PE4BAS my distance to CR1X who is in the Azores not Finland is 2417 miles per watt, thanks Bas for the info!  He had no  problem copying me so down went the power. I leveled out at 100mW's just for the reason this is as low as the K3 will venture.
Proof 100mW's is on it's way...no SWR showing

Below are the top 4 low power contacts all at 100mW's

1.  HA8JV            45,868  miles per watt
2.  IR9Y               44,558   "                        "
3.  9A1A              44,187   "                        "
4.  OL7C             42,496   "                        "

Until this contest my personal best Miles per watt 16,737 miles per watt when making contact with ZS4TS at 500mW's. Even at 100mW's being copied was easy and I was very surprised. I did not want to drop my power to the point were the contest station was spending his valuable time trying to make contact with me, but that never happened. I am now in the market for an attenuator do get my power output to below 100mW's and see what happens. I was looking at the Hendricks 41db attenuator. It's a kits and looks like a very nice unit.
