Lighter yagi’s
Over the summer I managed to ‘do’ 2 out of the 5 available 2m Backpacker contests. These to me are a great opportunity for me to get out on the fells and enjoy a longer spell on a summit with a nice qrp rig and some simple gear. The trouble with contesting is that inevitably you want to do better. So what’s the likely areas for improvement. Well there’s the rig, coax and antenna.
The rig is an ft817 and its not going anywhere fast. I sold once once then instantly regretted it. So it’s not going to be changed in a hurry. Yes it has its problems but frankly it just works and is relatively light so its a keeper.
Coax…Hmm work in progress. RG213 is too heavy, Ecoflex just isn’t flexy enough for summit packing. I’m yet to find the ‘perfect coax’. I’m leaning towards a trial with some Messi & Paoloni Ultraflex 7 as I like Mini 8 as a size but am looking for perfection here kids. This just means a reduction in losses to something as low as reasonably practicable as the saying goes
Antenna. Well I do like my now obsolete Sotabeams SB270 ( A 3 element yagi that lives inside its own plastic boom). Its light and doesn’t get thrown about too much in the wind and has lasted years. Trouble is it’s looking a bit knackered now and 3 elements is a bit short. I bought a 5 element LFA off innovantennas years ago and was really disappointed with the build quality. The elements just weren’t secure enough and it was way too heavy. Too heavy for a UKAC /p so no good for a summit. But it is well designed and the elements are quite light.
So the plan is to change the coax. I’ll do that over the winter. In the mean time I’ve taken a few grams off the yagi.
The boom was very substantial 32mm2 2mm thick Aluminium (note spelling you stupid browser ;-)). The boom weighs in at 1150g as is.Swapping this for 20mm2 1mm thick boom I’m down to 560g. Roughly half the weight. Element clamps have been swapped for the G1YBB method of IML mouldings plates and cheapo pipe clamps

You can see the immediate difference in size. The original beam is clearly made for sticking up at home then forgetting about it, ignoring the defects with this particular one.
Now with the elements added. They simply snap in to the pipe clamps and are held in place without any bother.

We’ll see how easy it is to carry up the Old Man of Coniston next year but at 1240g it is nearly 500g lighter than the original with the same RF performance.
I bought 2 pieces of aluminium and have a larger 2m and 70cm DK7ZB yagi that needs the same treatment (I went the other way this time, it was too light and flimsy) that I’ll give a run out during the Christmas Cumulative content
K0NR Colorado QSO Party Results
It was a fun day working the Colorado QSO Party from the cabin near Trout Creek Pass. State QSO parties are contests designed to focus attention on a particular state, with an emphasis on activation of counties. This brings out the County Hunters and other folks interested in working that particular state.I decided to operate from our cabin near Trout Creek Pass in Park County, which is considered “rare” by most folks. My station was a Yaesu FT-950 running 100W to a trap dipole up in the trees. I mostly operated phone since I don’t consider my CW skills up to that challenge of a contest. I did make a few CW contacts at the request of a few folks than wanted Park County on CW.
Thanks to all of the mobile stations out there, both in Colorado and out of state. I was surprised how many people were mobile or operating portable (often camping out for the holiday weekend). I normally monitor 146.52 MHz while up at the cabin for anyone out hiking or mobile. I heard Eric W0ECE doing a SOTA activation on Mt Evans and worked him for QSO Party points and SOTA points.
The score below includes the CW contacts so the score will drop a bit when I submit in the phone only category (77526, I think).
I was disappointed with the Qs on 15 Meters but I looked in my log from last year and it was also light on 15 Meter contacts. Twenty meters is always a bit crowded and I really like when 15M and 10M open up. I almost doubled my score from last year, so I was happy with the result.

Colorado QSO Party Coming This Saturday
The Colorado QSO Party will be held this Saturday September 1, from 6 AM to 10 PM Mountain Time. This is a fun radio contest where amateurs outside of Colorado try to work as many Colorado stations as possible.
It looks like we will have quite a few counties on the air for this event, so it will be a good opportunity to work any Colorado counties that you might be missing. Complete rules are available here.

Last weekend was a contest in the park.
| The setup at the park |
The first annual skeeter contest….done!!
| Packing up for the contest |
| The weather to look forward too |
watts with me calling CQ and not searching and pouncing.
The weather was a mixed bag from nice sunny skies (very rare) to very threatening overcast that did let go
| The setup...with a bit of rare sunshine |
with rain at times.Over the last month the temperatures have been in the upper 30's and low 40C...today it was nice and cool almost to the point of putting on a long sleeve shirt (which was used to cover the rig during light rain). The location I chose was about 15 minutes from my home and offered a pic-nick table, trees and what I consider a luxury when operating out and about a portable washroom!! The bands were busy with not only the Skeeter contest but the WAE contest as well. I did have some European stations involved in the WAE contest respond to my "CQ Buzz contest" Thats ok they gave me their report and serial and I asked for their power output and then they moved on this made it a skeeter contact....I believe anyway???
| Covering for rain drizzle |
| When it really rained |
| Finally...a must have!!! |
Weekend happenings……..
| During the NAQP CW contest |
On Saturday I took part in the NAQP CW contest. It was this day and mostly early evening and evening that the thunder and lightening storms came my way. This limited my on air time in the contest. I entered as QRP at 5 watts and was going to lower the power into the mW range but the conditions would not allow it. I was having a hard enough time making contacts with 5 watts.
| First time it has been blank |
So that is how the weekend more or less went here at VE3WDM!!
Soon there will be a new KX3 coming to town…
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.
