Soon there will be a new KX3 coming to town…
To help raise the funds for the new Elecraft KX3 some items here at the shack have to go up for sale....including my beloved KX1!! I have a new page with all the "for sale" items on it have a look and see if anything there can find a home in your shack. Yes Yes there was a post on my blog regarding my Elecraft K2 and how it was just fine (and it still is) and I did not need a KX3........BUT the bug has bitten.........and it has gone from a need to a want!!!
Other goings on at VE3WDM
When I ordered my Elecraft K3 some years ago I had it outfitted with the 100 watt module....as most you know I am not a QRO op....not that there is any at all wrong with QRO but for me QRP and QRPp is the best option considering my stealth operation. So the 100 watt module (KPA3) was put up for sale and sold in 1 day to help fund my KX3. Now my Elecraft radio is what is called a K3/10 (10 for 10 watts max output). Removing the KPA3 meant taking out my Sub receiver from the rig, the NB board along with some jumper cables. When events like this come I just hate opening up a 5K rig and playing around with the "stuff" inside. All went well and it's back together and working just fine.
I tried and I tried and tried to contact CY9M but it just did not work out that DXpedition is not shut down and it just was not meant to be. This weekend is the NAQP CW contest it starts at 2pm local time and runs til late evening. I am going to give this popular contest a go considering the not so good propagation lately this local contest will be fun even with max 5 watts.
I have an Elecraft K2 with the internal battery pack and up to this point I really have not been charging the internal battery to optimize its life. Some time ago I came across A&A Engineering They offer a great charger for the Elecraft K2 internal battery. I ordered it and it arrived in no time it's waiting to be assembled because....surprise surprise.... I ordered the kit!!
As for my kit from DIY electronic kits the USB 0-500mhz USB power meter kit has been soldered and is all together BUT is seems it has to be calibrated as the output of the rig is not even close to the readings I am getting with the kit. I have emailed the DIY electronics company over and over again but nothing.......seems that was 90.00 down the drain. I am going to keep it up and if I can I want to find a phone number I will then call them and demanding a refund!!! On an up beat note I posted a short time ago about a kit that I ordered and put together call the QRPometer. This kit is a great QRP watt meter and SWR meter but it only goes done to 500mW's..........now for most of you that is just fine but not here at VE3WDM!!! I like to operate now and then at QRPp levels. This means I need a meter that will give me good and reliable wattage readings from about 10mWs up to 100mWs. This was the reason for me ordering the USB 0-500mhz USB power meter it brags of getting down to the low mW levels..........IF YOU CAN GET IT TO WORK AND GET THE DAM TECH SUPPORT TO EMAIL YOU.........take a deep breath......ahhhmmmm.........ok Im back. Talking with the 4 state qrp group (those who produce the QRPometer) I am told the meter can have it's decimal place changed!!! This would give me the QRPp readings I need. This is a project that is now in the works and I will keep the blog readers posted as to it's progress.

In conclusion I always like to preview my blog post before it has goes "live" and for some reason the post is DOUBLED SPACED I have looked into this but am unable to find the answer..........keep you all posted on this one!!
IOTA contest and CY9M DXpedition
I was planning on spending some time this weekend participating in IOTA contest...but...I got called into work and by the time I got home and settled in I was only able to put in about an hour toward the contest. This is the first time I had taken part in the contest and was surprised at the turn out, this is a very busy contest for sure. I had hoped to add to my DXCC count by taking advantage of some of the rare islands. I did hear lots of rare DX but that was as far as it got to making any sort of contact. I found the bands to be so so there was an M6 flare along with an R2 radio black out that did not help out conditions. Despite the conditions I was able to make 8 contacts.
On all my contacts I tried with the lowest power possible and worked my way up until I made contact. If I was at full output (5 watts) and still could not make contact it was time to move along.

2) VE1AL NA010 5 watts
3) DL5AXX ------- 5 watts
4) M05BFL EU005 5 watts
5) DL8FBL ------ 500mW's 8,014 miles per watt
6) 9A/OM8AA EU016 500mW's 8894 miles per watt
7) S58VU ------- 3 watts
8) G6PZ EU005 100mW's 35,262 miles per watt
| Pile up for CY9M on my P3 |
I had seen CY9M on the band scope but they were super busy and with my 5 watts I felt I did not stand a chance. This morning there was an email on the Elecraft reflector from WB2LQF stating he had worked CY9M on both 20m and 30m's with his Elecraft KX3 and using 5 watts to do it!!! So I am back at it now and it's still busy but I am going to give it a go again this afternoon and evening. I just checked out WB2LQF's web page (see link above) he also uses attic dipoles such as myself.....now it's GAME ON!!!
A first time for everything.
I have been a ham for some time now but there are some things I just have not done as of yet......I can now cross off one more "not done thing" and make it DONE!! To some this may be old hack and you have done it hundreds of times. I was on the radio on the weekend and I heard VP2MUQ down in Montserrat, this is not a new DXCC for me but I did notice here was operating split (transmitting on one frequency and receiving on another). I had two strikes against me before I even gave Bob (VP2MUQ) an attempt. He had a large pileup and he was operating split. Up to this point in my have carrier I have never been able to make a contact when the station was operating split. It made me wonder if I was doing the split thing right or wrong. I had tried many times in the past but was not able to make contact with ANY op using split. Well on July 21 2012 that all came to an end. I setup the offset for the split (the split according to a spot on a cluster) and gave it a go.....nothing.....but there was a large pileup so I gave it a couple more goes. Then at 01:15 UTC VP2MUQ came back to me and before you know it I worked my first split. Well that's it for the post not very exciting to some but to me it was GREAT!! I now know I have been doing the split thing correctly all along. Another item stroked off the ham bucket list.
WOO HOO BY5WJ…..China with QRP!!!
This evening I wanted to get on the radio to catch some DXCC's for my Diamond ARRL award. The bands were not to full of the DX that was needed for my DXCC award BUT St.Pierre et Miquelon
is a self-governing territorial overseas collectivity of France and is just outside of Canada, some Canadian hams were there making contacts on 20m!!! It was a DXCC I did not have and it's more or less local....easy peasy.............so I thought. The pileup was huge and I never did make the contact. Later in the evening they were on 40m but I was not able to hear them at all. It seemed I was the only one not able to hear them by the size of the pileup. Oh but earlier China BY5WJ was on the cluster and I thought "what the heck " and holy cow there were LOUD AND CLEAR....I gave them a go but again the pile up was big but I wanted to stick with it as they were just blasting in. While others were making contact I went to QRZ.COM to get some info as I always do...........this is what I found........
Oh and I already have Jamaica' well it was good I found out before
calling "BY5WJ" for 30 or more minutes. Lesson learned be careful even
of the DX cluster spots. As a side note this is a mistake I or anyone could make and it's nice Josh put the info up on QRZ.COM to clear the fog.

Although it would have been satisfying to have worked BY5WJ in China,
I'm sorry but either I sent the wrong call or your ears are defective. In fact
you worked 6Y5WJ in sunny Jamaica. If I sent the wrong call then I'm
sorry I need, to practice, a new key, a keyer or radio :) :), either of which
can be sent to me at the above address. If however you wrote down the
wrong call then I will send YOU either a new pair of headphones, a new
rig or a syringe of warm soapy water:)

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.
ITU 9
HQ contacts 6
Points 46 UPDATE: score was actually 690 have to stop using that new math!!

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 |
| Final testing |
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
- Have fun and enjoy!!
- Look for DXCC's I do not have so I can add to my ARRL Diamond count.
- See if I can beat my miles per watt record of 45,868 miles.
- Have fun and enjoy!!

Solar storms VS QRPp
This week we all have seen sunspot 1515 working overtime producing solar flares. It has been some time since a sunspot has consistently produced M class flares sometimes 2 or 3 in the same day. As amateurs we like to see rising sunspots, rising Flux numbers and a falling K index. ( as a side note this link is a great index for all those propagation words you wonder about)...BUT....along with an active sun also can come increased solar flare activity, increased solar wind which can bring a downturn for radio conditions. As a QRP/QRPp station I take these conditions as a challenge I also understand that during these times for me DX may mean contacts in the U.S. This week I have tried to get on the radio for a short time each evening. Using the Reverse Beacon Network (RBN) has been a great help giving me an idea which bands were open and just where my CW signal was being heard. Below is the results of one of my RBN sessions
K3MM in M.D. 21dB
WZ7I in P.A. 18dB
K1TTT in M.A. 11dB
KB9AMG in W.I. 9dB
Most of the time I would be heard in Europe but with conditions the way they are the U.S. seems to be my DX destination for the time being. I fired up the K3 along with DxLabs. Right off the bat I saw lots of spots for Europe but was not able to hear them on this side of the pond. I then heard an S5 signal from SM5EPO from Sweden. I knew conditions were not that great and after all the RBN confirmed that on 20m's it was the U.S only.........So I dropped the K3's power to 100mW's Heee Heee Heee and gave it a go. SM5EPO came back to me and with a few repeats the contact was complete at 39,111 miles per watt. In the past when conditions were good and I was making QRPp contacts and logging the miles per watt I wanted to see how I would do if conditions were not ideal.
