Delta Loop for 10 Meters on a Buddipole

Vertical Polarization 

Horrizonal Polorization of Delta Loop Good for DX

 

The magic that makes this antenna possible is a TRSB, Triple Ratio Selectable Balun. There is a 2:1 ratio position on this balun that is reversed for a 1:2 ratio to match the coax to the 100 ohm antenna. Any balun with this ratio will work.

Ten meters is doing pretty good lately. It sure is nice to have this band open again. I worked Alaska and Argentina on 10 meter CW using this antenna. I replied to an Ea7  station on SSB but he didn’t hear me.

The Delta loop is easy to configure and easy to deploy. These photos were taken on the porch of my condo. I’ll take this delta loop to the beach when the WX clears. I needed a rainy day to catch up on things around the house.

Here’s a nice video featuring a Buddipole Delta Loop http://www.youtube.com/watch?v=Ikm-HICGcrI&feature=youtu.be

This antenna can be used on 12 meters also and on 15 and 17 with additional Buddipole Arms and a longer ‘home brew connecting wire’ to close the loop.

I’ll be trying these bands out at the beach, my usual ham radio portable venue.

Still alive and kicking (just!)

It has been a while since my last posting to this blog, which has caused a couple of readers to express concern about my current state of health. I’m glad to say that reports of my demise are exaggerated, but less happy that the intensive chemotherapy regime has left me feeling pretty lousy and afflicted with a severe lethargy that nothing less than the arrival of Santa Claus bearing a shiny new Elecraft KX3 could kick me out of. Even reports that 10 metres is wide open have not given me the energy to haul my ass into the shack and see for myself. Hence the lack of posts.

I don’t see things getting much better for the next 4 months when the chemotherapy will be over as although I do detect an improvement in how I feel as I get towards the end of a cycle I am quickly back to square one after starting the next one. There is not enough change in how I feel from day to day to warrant more frequent postings to One Foot in the Grave. My days seem to merge together so that most of the time I couldn’t even tell you what day of the week it is!

Despite what I have just written I will not actually be one of the people feverishly refreshing the Elecraft order page in order to secure a place near the top of the list for KX3 orders. Though I don’t doubt that the KX3 is a seriously cool piece of radio equipment that will be a big success for Elecraft, I have come to the decision that my FT-817ND meets all my current needs of a portable ham radio. I also can still remember my frustration at the length of time I had to wait to receive my K3 (and the even longer wait until the firmware actually worked and it all performed as expected.) I don’t wish to cause myself the stress of wondering whether I will live long enough to receive my KX3!

That’s not to say I don’t see an Elecraft KX3 in my life (and my shack) at any point. I can envisage a situation where a new toy to play with could make life seem a lot more cheerful. One day it will be possible to order a KX3 and get instant gratification. But until then I’ll content myself with reading the experiences of the early adopters and watching their YouTube videos.

One on one with the PC………

The CQWW DX CW contest was a blast and before the contest I did some thinking as to how I could best take advantage of the computers that I have at VE3WDM. I brain stormed the week before and came up with the idea that my main desktop PC would run my K3, logging program and propagation stuff. I could use a net book laptop to look at QRZ.COM, email and so on. So it was decided one monitor would look after the main PC "stuff" and the other would be hooked up to the net book and run the other "stuff". This plan worked great and I
was able to multi-task during the contest between two computers using two nice LCD monitors. The next day after the contest the net-book was snuggled in it's case and it was time to use
During the contest with both monitors

both LCD monitors on the main PC as it always had been done....As the PC booted up the one monitor display read "not connected". I then preceded to connect reconnect and change out the video cables but nothing had worked. I was still getting the "not connected" message floating around. I then in WinXP had a look at my video card. Maybe I just had to tell the PC to recognize the other monitor again. In the process of trying a dual monitor setting I did not read the warning that was counting down from 15 seconds. I just said "ok". Well now both monitors were blank with the message "not connected" Well that went well!!! It was off to Google to solve my troubles. Seems the net-book could had changed the monitor refresh rate and or resolution settings. Settings the main PC was not able to recognize and thus the message "not connected". According the the advice derived from Google searches I have to boot in VGA only mode. It was simple, I was told "wait for the Windows logo to appear and press F8". Easy if both monitors were not blank!!! So began the many restarts guessing when to press F8. Well in time I was successful and was able to get into VGA mode and repair both monitors. All is working well now and lesson learned. It turns out the net-book changed both the refresh rate and the resolution.

A Ham’s Night Before Christmas

‘Tis the season to be jolly and give of yourself to your fellow man. Though I think that should be all year long, but still, around this time of year, it’s nice to spend time with friends and family and enjoy the time. This year I am feeling especially festive, simply because I am with my family. I know, I’m easy to please. But one of the other things I like this time of year is of course the entertainment. It’s a tradition for me to watch Miracle on 34th Street every year during the holidays. And this one may be a tradition I do every year. Post (or repost from this point on..) “A Ham’s Night Before Christmas”. The video is done by Gary Pearce, KN4AQ, with guitar melody by Don Mercz, WA3AYR. So sit back with your coffee or hot chocolate, grab a candy cane or a sugar cookie, and enjoy!

Last weekends contest disaster

I did participate in the EPC Ukraine PSK63 contest on 80/40m and the 10m RTTY contest last weekend for a while. Goal was to score some points for the “afdelingscompetitie” (local divisional contest counting). I did make 105 QSOs in total. 78 in the EPC contest and 27 in the RTTY contest. Not much, but not bad since I didn’t spend hours on the radio. Unfortenately N1MM did not support the EPC contest, I could not fill in the exchange UR12 for example, and I had to switch over to DM780 to continue. After all I cannot merge both ADIF files to a good one for conversion to cabrillio and I do have some errors counting as well. I actually made a total mess of it, so I’m sorry I will not send in my log. These russian contests are supported well by mixW, but that is not a free program and I don’t like to work with it. It doesn’t have the “feel” I like from a digital modes program. It could be personal.

Summits On the Air Taking Off in Colorado

The Summits On The Air (SOTA) program was launched in Europe in 2002 but is just now making its way to the United States. Recently, there has been a surge of activity in Colorado as the program gains traction here.

The basic concept of SOTA is an award program that rewards the radio operators that activate summits and the radio operators that chase summits. For those of us that enjoy the mountains and enjoy ham radio, this is a great fit. I won’t go into all of the rules here (Warning: There Are Lots of Them), so check out the SOTA web site for the complete details.

Steve WG0AT (World Famous Alpha Goat) just published another one of his Rooster and Peanut videos that capture his recent activation of Mount Herman. I managed to work Steve on 2 Meters and I make a cameo appearance in his video below as I make my first official SOTA contact.

Steve has been activating SOTA summits for a while now and others are joining in. Here’s a video from Pikes Peak with Mike, KD9KC and Ron,WT5RZ on North American Summits On the Air weekend.

Recently, Jerry KD0BIK succumbed to the SOTA addiction, activating Mount Herman and  Green Mountain (click on the mountain names to see his blog postings). Chris NW5W has also been active…check out his web site here.

There are numerous SOTA videos on youtube from all over the world.

The SOTAWatch web site is dedicated to posting future SOTA operating plans (Alerts) and SOTA activations in progress (Spots). The North American SOTA Yahoo! Group is another great source of information.

See you on a summit soon.
