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 the Field” 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!

9N1 Emergency

Some New Toys .....

Received a couple of new toys today from Buddipole to add to my private stock of their parts.

I ordered the mini-coil which is perfect for use with the large collapsible whips and I also ordered the five section rigid shock-corded adjustable whip.  This whip extends from 22" to 142", and allows you to operate on 10m to 17m by itself, no coils or additional arms.  It will also cover 20m with the addition of two-22" arms.

When I use the Buddipole I very rarely ever use it as a dipole...with the exception of 10m, where it works very well, normally I use it in the vertical mode, so this one whip will allow me to pack just one whip and two arms and operate from 10m to 20m.  Bonus!!!

I have had great success over the last 10 years working all kinds of DX with my Buddipole system.  I've slowly added a lot of extra parts to the basic kit I originally bought, so it's a good job the XYL doesn't look in the shack closet very often.

You know, the only problem getting new toys like this is trying to find the time to play and experiment with them.

Busy Weekend.....

What a great weekend for the QRP to the Field event!  There were lots of QRP stations calling CQ, more on CW than SSB....as per usual, but they were out there!   I managed to put 31 in my logbook this weekend, not including the SOTA contacts I made as well.

Our weather this weekend was on the cool side, and it did in fact rain just a little.  Over all though I won't complain....it didn't snow!

The IC-703 and my Buddipole are a winning combination it seems.  There are more Buddipole parts on the way and should be here this week......and my radio club has an island activation coming up soon, so talk about good timing!

There seemed to be a good number of SOTA activations going on in North America this weekend as well, and I did manage to put 44 activator points in my log.

Unfortunately some collective efforts to get a VE3 SOTA Association up and running over the past three years have fell foul of the SOTA management team rules about only allowing peaks that are a minimum of a 150m prominence to qualify.  We don't have too may of them here, it's true that there are a good number north of Sault Ste Marie and Thunder Bay, but around where the main ham population lives in Ontario there are none.  So all we can do is chase those guys who can activate summits in their part of the world.

It's really great to see the rise in both QRP and SOTA activity on the airwaves, and hopefully it will continue as we slide down into another solar minimum.

Not Much Contest Activity

It was a pretty quiet weekend for the Ontario QSO Party.  Saturday most of the SSB activity was between 7.060 and 7.099 and stayed there until evening and then it moved to 80m around 3.730, but to be very honest I didn't hear too many stations calling for the QSO Party.

There was lots of traffic calling for the Michigan and Nebraska QSO Parties so it wasn't like the bands were in bad condition.  Saturday afternoon the SFI was: SFI-148.  SN-93. A Index-25, and K Index-2, in fact those numbers never changed all weekend.

I did manage to find a few contacts on 20m on Sunday before the contest finished but it was pretty hard slogging most of the weekend.  There was a bright spot though.....I did work VA3QV on Saturday evening!  Yes, the ever elusive Bobster is in the log once again.   For the Ontario QSO Party I managed to put a dismal total of 26 stations in the log.

The IC-703 performed as advertised and I had many good signal reports over the weekend.  Obviously the punch of the 703 and the height of my dipole is a winning combination, I think I'll leave everything as they are as I've tweaked everything as much as I can.

In between hunting elusive VE3's I also spent some time hunting SOTA activations using the SOTA Watch website (HERE), and I managed to snag three USA activations over the afternoon.   It was a lot of fun working those guys and I actually had QSO's with them, not just a quick "59, Thanks, QRZ?"

I also worked four DX stations on Sunday afternoon, R120RM in Moscow, S57V in Slovenia, J79MM in Dominica, and AO2015WRD in Spain.   Not too bad for a QRP station.

QRP To The Field

Coming up on Saturday, April 25th, is this years edition of QRP to the Field.  I always enjoy this event although I don't always submit my results.

This is one of the very few QRP events that has a SSB category so the IC-703 will be getting another workout this month.  It's funny as I was talking about selling the radio but I find I'm using it more and more these days, so it's off the market.

The event also includes the use of local SOTA Summits......which we don't have in VE3 Land, but it's still a great excuse to head out and operate portable from you favourite park bench in some little park.

SSB Frequencies to use are: 3.985, 7.285, 14.285, 21.385, and 28.885.

This event runs from 0900 to 1800 EDT......hope to work you on the bands that day.....and that means you too QV !!
