Bouvet Island DXpedition - 2016

Sad news today that Mark, ON4WW, will not be doing the Bouvet Island DXpedition next year.  

Mark's plan was to do a solo DXpedition and to do it over a three month period.  Over that amount of time nearly every ham who needed Bouvet Island could have had it in their logbooks on numerous occasions, and on several bands.

Unfortunately, Mark was unable to collect sufficient funding for this adventure.  For some reason the big DXpedition supporters and donors were not very interested in this event and not many donations came through.

Mark had received permission for Bouvet from the Norwegian Polar Institute, his wife (very important!!), and his employer to have 5 months leave without pay.  I'm sure Mark is bitterly disappointed that his year long planning has been all for nothing.

I think Mark's plan to go solo, although a bit controversial, is one way of keeping these DXpeditions to far away and remote locations sustainable.  If we look at the cost of doing some of the more recent DXpeditions, including K1N, they have been out of this world.  I truly believe that smaller and more compact teams are the answer to keeping the skyrocketing costs down.  

For safeties sake I think it would be a lot safer to go with a minimum of three people, going solo does seem a bit dangerous to me, but that's Mark's decision to make, as he knows his own limitations better than anyone.

One must ask if we really need five to eight HF stations on the air, all at the same time?  Or, could a DXpedition get by with just two or three?  Do we need to be spending thousands of dollars transporting beams and Yagi's to these remote sites.........when many of us work the world on simple dipoles at home with no problems?   Perhaps the whole idea of how Expeditions are conducted needs to be reconsidered and discussed in depth.  Bigger is not always better!


While I occasionally dream of doing a major DXpedition to some far off remote location, I think for now I'll stick with my own mini-DXpeditions to Wolfe and Simcoe Islands, where the most expensive aspect of the trip is buying lunch on the way back.  That's more in keeping with my budget.......

An interesting morning....

It's been a beautiful day here in Kingston, 20C under mainly blue skies.  I have been busy over the winter season trying to lose some weight, and as a result have been walking just about every day at the Cataraqui Centre Mall.  This has allowed me to walk and climb stairs and get into shape for the "season", and it's amazing just how many people are in that mall each day just walking.

Anyway, yesterday I decided that the weather is becoming far too nice to walk indoors and it's about time I switched things up and hit the K&P Trail, part of the "Rails to Trails" program.

Of course the real reason I'm exploring this trail is to find some new QRP portable operating locations.  So far it's been a bust, but there is a lot more to walk before I give up.  It was a fantastic walk today, lots of birds singing in the trees, the Trilliums are starting to bloom along the trail edges, and lots of Garter snakes out sunning on the path as well.

Of course before I went to the trail I did spend 30 minutes playing up on 40m.  I checked into the Trans-Provincial Net which meets on 7.055 MHz daily 7am to 5pm.   Not every hour slot is filled so if you don't hear a controller get on and call CQ Trans-Provincial Net, you never know who will reply to you.

Take today, guess who popped in and called me???  Yes, the Big Bobster himself, VA3QV, with a screaming 5 watts coming from his Flex-1500.  I gave Bob a 55-57 into Kingston and Tony, VE3DWI, up in Debarats also gave him the same signal report.  Not too shabby for 5w at that time of day.

All in all, a good day......and I got to chat with Bob!

Buddipole Experiments Part 2


16' 8" fully extended whip
The last piece of equipment that got tested today was the SkyWhip Portable Telescopic Antenna that I bought from Durham Radio a few months ago.   Due to the bad weather it's sat in my Buddipole case until today.

This antenna has a fully extended length of 16' 8", and can be used for any band between 6m and 20m.   I certainly would not use it in a stiff breeze fully extended, but with the light breeze I had today it was fine.

The good thing about this piece of gear is that it fits the Buddipole parts perfectly, I don't have to carry different mounts for it.

I wanted to try the antenna on 20m, so I set it up on the 8' painter pole over average ground, just like the other tests I did today.

Using the SkyWhip Portable Telescopic Antenna and the TRSB set at 1:1, at 14.150 the SWR was 1.2:1 and I used a 15' 10" counterpoise.  It worked as advertised the very first time.  Beauty!!

So it looks like I'm all set for the planned island and lighthouse activations I have planned this summer.  Some of these antennas may even get thrown in the mix for this years Field Day.

Coming up as soon as I can find time will be the same type of article on the Buddipole 40m, 60m, and 80m antennas.






Buddipole Experiments

A dirty truck bed!!
It’s a beautiful day here in Kingston, blue skies and 17C, just a great spring day.  In fact it was so nice I decided that today would be a good day to conduct some trials with my stockpile of Buddipole parts.

I have been looking on the internet over the past few months for information on the new shock corded adjustable whips, and have found almost nothing on them, including just minimal information on the Buddipole site itself.  I did talk to Chris Drummond, W6HFP, the owner of Buddipole about the lack of resources and he agreed that there was very little out there.  I did ask Chris if he could put some baseline seeing on the company website to at least give us all a starting point to start our experiments, and he said he would.

So, armed with a copy of the book written by Scott, NE1RD, “Buddipole in theField” I collected all my antenna parts and off to the garage and my gravel driveway I went.  If you have not downloaded a copy of Scott’s book I recommend you do.  It’s available as a free download from the Buddipole website.  This book is a great place to pick up the information to build better Buddipole antennas, and it also gives you a basis for experimenting with the extra parts.

My Buddipole parts box consists of a Standard Buddipole kit, two extra 22” arms, a TRSB, a 12’ Shock cord whip, a 9 section mini-shock cord whip, and a 5 section rigid shock cord adjustable whip.  I also have a mini-coil, two regular coils and a low band coil, and a set of 9.5’ long whips.  More than enough to build any antenna I will need.

My goal today was to figure out some workable ¼ wave vertical antennas where I didn’t have to use any coils. I wanted full sized antennas with no compromises.  Today I looked at 10m, 12m, 15m, 17m, and 20m. 

The standard items that remained constant throughout the tests were each antenna was mounted on an 8’ painter pole, and it was done over average ground.

The first test, on 10m, was done using the mini shock corded whip.  It took several attempts to get this antenna to the point it was useable.  Here are some numbers:

Using the mini shock corded whip, with no stinger used, at 28.500 the SWR was 5.7:1 with a counterpoise of 8’ 4”.

Using the mini shock corded whip, with the 9” stinger extended, at 28.500 the SWR was 7.0:1 with a counterpoise of 8’ 4”.

Using the mini shock corded whip, with the 9” stinger extended, the small coil at tap 3, and at 28.500 the SWR was 8.4:1 with a counterpoise of 8’ 4”.
 
Obviously the standard setting was just not working for me today, so I changed things up.  I used the mini shock corded whip, with no stinger used.  At 28.500 the SWR was 2.6:1 with a counterpoise of 6’ 11”.   And that was as low as I could get the SWR on 10m, but to be fair the antenna is a bit long for the band.

The next test was for 12m, not a band I use very often but I have made some great DX contacts there.

Using a 5-section rigid shock cord adjustable whip, with no stinger used, at 24.950 the SWR was 1.4:1 with a counterpoise of 8’ 4”.  No point messing with this one as I don’t think I could get it closer to one to one.

Next up was 15m, a band I use quite a bit for chasing European DX. 

The Buddipole TRSB
Using a 5-section rigid shock cord adjustable whip, with 4.5” of the top stinger used, one 22” arm and the TRSB set at 2:1.  At 21.175 the SWR was 2.1:1 with a counterpoise of 12’. 

Next was 17m and a band I like and use a lot,

Using a 5-section rigid shock cord adjustable whip, with 5.0” of the top stinger used, two 22” arms and the TRSB set at 2:1.  At 18.136 the SWR was 1.9:1 with a counterpoise of 12’.   I messed with this antenna for quite some time moving the counterpoise length up and down, and I could not get a better SWR reading.

Last up was the 20m antenna.

Using the 12’ shock cord whip, two 22” arms and the TRSB set at 4:1.  At 14.150 the SWR was 3.3:1 with a counterpoise of 15.6’.   No matter what I did with the counterpoise length I could not get the SWR any better.


It was interesting that most of my counterpoise lengths are very different from what is recommended in “Buddipole in the Field” by Scott, NE1RD, by a good margin.  It would be interesting to hear what sort of ground Scott as using when he did his experiments.  From what I saw today it is very true that the counterpoise lengths are very critical to the tuning of these verticals.

Obviously there is still some more experimenting to do, but these are a starting point and  enough to get me on the air quickly.  Still to come are the 40m, 60m, and 80m antenna configurations.

If anyone has any ideas to make these settings better, I'd love to hear about them!
