Antenna Comparisons...

On June 19th I wrote on this blog that I would like to see what the QSO pattern difference was between my operating using 10w and hamsticks versus my using 5w and a 40m EFHW up at 33 feet.

The EFHW was set up as a sloper along the East to West axis.

One difference in this experiment is that I changed operating locations by 115 km (71 miles) to the west of my home QTH. Another difference is that I dropped the power from 10w to 5w so I was legal under the Field Day rules.

So was there a difference?  Well, not really.  If you look at the QSO maps I have published over the past few months in the articles below this one, and then have a look at my Field Day contact map shown below, you will see virtually no difference in the area my contacts are made in.

Here's my stations Field Day map:

To me this shows that the difference between a 40m EFHW and a properly tuned and set-up 40m hamstick is negligible.

Field Day - the aftermath...

What a weekend!!   After the last two years worth of Field Days with the hundreds of high power 1D stations taking part, this year was very different.

It was a 90 minute drive to our field day location and the weather was just perfect.  It took us no time to set up the two screen tents we would operate from, and the rest. of the camp.  I managed to get one antenna up by late Friday afternoon, which allowed me to chase some POTA stations that evening.  it was a good test of the system.

In the end I ended up with two antennas in the air, a 40m EFHW, which was set up as a Sloper, pointing west, and a 20m vertical (shown to the left).  Both worked very well, especially the sloper.

The propagation on Saturday was: SFI=115, SN=60, A Index=8, and the K Index=3.  Not the best, but better than we were advertised to get.  It was as 28C and we had a good breeze blowing on Saturday to keep the bugs away as they were just horrendous.

At 1800 UTC the bands exploded as Field Day kicked off, and it was only seconds before I had my first contact in the log.  I found that going after the very loud signals to start with really increased my QSO count, I saved the weak stations for Sunday morning when they were getting desperate for contacts and were listening for any new one they could hear.  40m was my go-to band, and I worked the majority of my contacts there.  However, early Saturday evening the propagation went to hell and as a result 40m dried up.

I decided to try 15m, which was a good idea as I made a dozen contacts there, including a solid contact to the southern part of Argentina.  Not too shabby for 5w!!

The propagation numbers for Saturday evening into Sunday were:  SFI=108, SN=60, A Index=16, and the K Index=5.  Not too good at all.

Over the course of Field Day I logged 77 contacts, all 5w SSB QRP.  The interesting part is that after my complaints about the huge number of 1D stations over the past two years, I only worked three 1D stations all weekend, I just didn't hear them.  I did manage to work a large number of club stations with multiple operators...just like the pre-covid days!  And that's a good thing. Maybe we've turned a corner and are slowly getting back to normal?

All-in-all it was great weekend, and all of us there had no problems at all operating at QRP levels.  

I'm hoping it will improve some more before next Field Day!

propagation numbers Saturday evening!

Field Day Preparations Continue...

The preparations continue for Field Day.  This year we are travelling 90 minutes west to Grafton, Ontario, to a site we have used before, when our normal site was underwater a few years ago.

The back of my van currently looks like a cross between a Radio Shack Warehouse and a Camping Store.  There is gear everywhere!!  I didn't realize that I owned so much equipment.  

The weather forecast so far is calling for no rain, and hopefully the propagation Gods smile upon us both days, although it looks like we may have a rough start on Saturday according to Space Weather. 

Don VE3MNE, and I are heading out Friday afternoon to get the camp set up and to try and figure out where we can site and hang our antennas.  This year we plan on operating as a 3A station, made up of a SSB station, a CW, and a digital Station.

The antenna line-up, so far, is a 20m/40m linked dipole dipole, and several EFHW verticals for different bands.  Friday evening and Saturday morning will be spent getting these antennas in the air and checked out....and perhaps making a few POTA contacts.  

Stay Safe Out There!!

The Weekend in Radio...

It certainly has been a lousy weekend for doing portable radio.  The weather was fine, the band conditions not so much!

On Saturday the propagation numbers were: SFI=149, SN=152, A Index=13, and the K Index=2.  The QSB on both 20m and 40m was very bad on both days, with S9 stations disappearing in seconds and coming back as S1 or S2 before fading away completely.  

The map below shows my contacts on both 20m and 40m.  The majority were on 40m, which is opposite to what was forecasted for that day.  20m should have been the "go-to" band, but it was nearly dead.

Then we come to today.  We have pretty much the same propagation numbers: SFI=140, SN=146, A Index=14, and the K Index=2.  The QSB was still there, but not nearly as bad.  And, as you can see from the map below, my contacts were in and around the same areas.  

Both park activations were done with the KX3 at 10w, and as usual the 20m or 40m hamstick on the roof of my van.  

It will be interesting next weekend, Field Day, to see what my contact plot looks like.  I will be operating about 115 km west of my home QTH, so we will see if a location change, and using wire antennas makes a difference.  My bet is that it will......let's be honest, using wire antennas instead of the hamsticks must make a difference.

Stay Safe Out There !!

Rideau Lakes Cycle Tour

Next weekend, June 11th & 12th, is the 49th running of the Rideau Lakes Cycle Tour, and the 14th year the Frontenac Radio Group has provided communications support for the event.  After a two year hiatus we have managed to scrape together enough volunteers to look after our normal communications locations.  This Saturday will be the first time in 2 years we have had the whole gang together, in person, since Covid hit us.

We do have the threat of rain on us this weekend.  It's only a 30% chance, but it's not a thing we need or want.  The last time we got hit with cold rain was 10 years ago, that year 60% of the riders went down with hypothermia with the tour being abandoned half way, and riders evacuated by bus back to Ottawa.

There are only 1300 riders registered this year, the numbers being reduced from the more normal 2100 due to covid concerns.

For those hams who regularly use the VE3FRG repeater here in Kingston, please note it will be out of service next weekend and reserved for the Bike Tour traffic only.  If you need a repeater please use the VE3KBR repeater on 146.940- with a 151.4 tone.

If you're in any of the locations shown on the map below over the weekend, please watch out for the cyclists.

ARRL Field Day 2022...

Now, last year, after Field Day finished, I wrote that I wouldn't take part in it again due to the silly rule changes the ARRL had made because of Covid 19 that ended up making a total mockery of Field Day.   Then early this year I commented, negatively, about the ARRL voting to make these silly rule changes permanent because it had allowed so many more hams to take part....never mind the poor operating habits and bad behaviour those changes had encouraged.

I still think they are silly rule changes, nobody will change my mind on that.  It's called "Field Day"....not "Sit at home and operate from the comfort of your Shack Day".  Field Day is supposed to make you think, and operate, outside the box.  It was designed to make you travel to, and operate portable from an unprepared location, and then compare your results against those of the other participants who had done exactly the same as you had.

This is now hard to do when operating from a temporary field location, operating from batteries, using less than optimum wire antennas, when the people you're comparing yourself too are using 1500 watts with professionally installed towers and beams...all from the comfort of their normal home shacks.  It seems to me that the whole spirit of Field Day has been thrown away in order to make the event "bigger and better".

This year I have decided that I will in fact operate during the event.  I have been invited to Northumberland County to take part in a QRP Field Day.  You know, 5w maximum, and only home-brewed wire antennas allowed.  I'm going to have fun, tell tall tales and swop lies with friends I haven't seen in two years, and I will ignore those lazy individuals who decided to stay home and operate from the comfort of their own homes instead of following the true Spirit of Field Day.

It's going to be fun.
