Field Day 2022

By: VA3QV
14 June 2022 at 17:09

Traditionally held on β€œThe Last Rainy Weekend” in June but for the sticklers for the rules its actual date is the 4th weekend in June…

This year it would be on June 22nd and ending on June 23rd

So what will VA3QV be doing???? Its safe to say that my Field Day Station will look a bit like this:

or like this from back in 2017….

FD 2017/ RAC Canada Day Contest 2017
Won’t look like this…. This was an early Winter Field Day attempt

So I plan to be operating as a 1B Battery Station from the RAC Ontario East Section (ONE)

The actual location has not been determined yet but there is a good chance the location could be one of the Parks on the Air location in the City of Kingston.

That’s the plan for good weather… and so far the long range forecast is calling for nice (dry). If the weather is not dry then the plan is to operate as a home station in the 1D catagory just to give out points to the participants

If you are new at this then the rules can be found here:

Years ago Field Day was considered a test of our emergency operating skills specifically to set up and operate a station for 24 hours and somehow it has morphed into more of contest with groups of operators putting up equipment that would not be used in a real emergency at power levels that could not be maintained unless you had a generator and an endless supply of gasoline.

I’m a little more primitive by setting up my QRP (5w of power) radio with a wire antenna and using a solar panel to top up the battery as needed.

basic shelter

I will have the option of being under cover (see above pic) as protection from the sun and/or rain most likely be needed at some time . Not sure how long I will be operating but it won’t be for the full 24 hours.

Overnight all I would be doing is listening to static and feeding the mosquitoes…

No egos to stroke…. Just operate and make some contacts with the emphasis of having fun and not taking myself too seriously.

Hope to hear you and be heard by you during the event

Bands getting a β€œbit” better and testing some gear

By: VA3QV

Well its not as bad as indicated from my last post…

But its still got a way to go…

This morning on my 11 am (Eastern) hour on the TPN I managed to get 7 stations in my log which is the best its been in a while. After the net ended I had some household chores to do before I could get to the next part of this post.

Today I wanted to take my Yaesu FT891 rig along with my two antennas out into my backyard and make sure everything is still working as well as I remember. Next week my shifts on the TPN will be ending for a while as I am taking the summer off in an attempt to concentrate on my POTA part of the hobby.

So here’s the setup

Rig: Yaesu FT891 powered by my ECO-Worthy 20ah LI-PO4 battery

Antenna 1: 40m EFHW which is 63 feet long and fed by a 64:1 unun. This antenna usually is used in a sloper or inverted Vee configuration. Its very nice on 10-40m and I have 2 small counterpoises which I clip on as needed. I feed the unun from a 25 foot run of RG58 with a RF choke at one end.

Antenna 2: 17.5 foot long end fed fed by a 9:1 unun. I normally would use this in a vertical or sloper configuration. Its excellent on 10m to 20m but will also work on 40m without the need of a tuner. Depending on the situation I have a couple of small counterpoises I can clip onto the unn if needed. I feed the unun from a 25 foot run of RG58 with a RF choke at one end. The advantage to this antenna is that if I use it as a vertical there is next to no footprint which could make a couple of the parks in the downtown area much easier to activate.

If the trees do not cooperate I also carry a MFJ 33 foot telescopic masting which will support the wire if needed.

How did I do today?

Operating from my deck I strung out the 63 foot EFHW kind of as an inverted xyz configuration. Hanging 63 feet of wire anywhere I could hand it without anyone seeing it or running into it. Despite the setup Contacts were made on 40m and 20m despite the band conditions. with a reasonable SWR (no tuner in line) where I normally use it

Next I used the 17.5 with the 9:1 unun as a low sloper and made 1 contact on 20. The SWR was β€œtolerable” on 40m but on 10m to 20m it was under 2:1 which is great for a Portable setup. Nothing to complain about on my part.

I also use this style of antenna at home in a vertical configuration and it works great for my need either β€œhome or away”

So here’s the plan…

If you notice the above map there are 10 POTA sites (yellow dots) that I can easily access from my home in Kingston. All of them easily reachable via public transit or a bit of a walk. The one on the bottom right (the island) is not reachable via foot. There is a dock but I can’t find out if Kingston has a Water Taxi so if I can activate 10 out of 11 I will be pleased.

I guess I could also say that this would be a test of the station I will be using for Field Day this year. Not sure where I’m going to be yet but…. I know I’ll be participating from somewhere near Kingston.

Till next time

Another antenna for the β€œPortable” Station

By: VA3QV
11 April 2024 at 18:52

If you look back to my previous post in which I had covered my successful POTA activation of CA5143 I mentioned that I had used my 40m EFHW antenna to make the 23 contacts made.

Well one thing I neglected to mention was the difficulty I had getting 62 feet (or so) wire stretched out in the rather dense brush just off the trail. In the past I had mentioned about getting a 2nd antenna in the kit for when the EFHW was just not able to be deployed easily.

I had tried a BuddiPole but it did not (could not) do exactly what I wanted…. Using some parts from the BuddiPole and then adding a β€œImitation” Shock Corded 9 foot whip (In my opinion…FWIW the Amazoon 9.5 ft shock cord whip is a real POS)was not doing it for me either. I tried following the instructions and when those did not work I tried (to no avail) to use what I tried in the past with other portable antennas but just no joy…

Fast forward to yesterday. The LDG 9:1 UNUN that I ordered on the Monday had arrived and so I decided to duplicate the β€œCoastal-20” antenna that I use at home for 10-12-15-17 & 20m. If you β€œGoogle Coastal-20 you should see the basic plans. Its a 9:1 UNUN along with a 17.5 foot vertical with a short counterpoise.

Now on my first build I found the short counterpoise version did not perform exactly as I had hoped so I decided to go with 3 elevated counterpoises. I cut 1 for 10-15 &20m and it worked quite well for me on 10 to 20m. By well I mean that I was making contacts and the SWR on all the needed bands was low or low enough that the internal tuner in my Yaesu FT991a was handling it.

Mostly copying my first version with the exception of swapping out 3 counterpoises for a single 11 foot counterpoise seemed to make no difference with the SWR and it was loading up just as well as the previous one did.

The next test for the new antenna will be when I get out into the Park (hopefully this weekend) if the forecasted rain ever stops. The plan is to have both antennas available for when I participate in the POTA Support your Parks event which happens April 20th and 21st and by strange luck is also the same weekend as the Ontario QSO Party, The Michigan QSO Party and the Quebec QSO Party so there should be no problems getting contacts to activate what ever park (parks) I head out to…

POTA activation of CA-5143 completed

By: VA3QV
6 April 2024 at 19:55

This was a special one for me. The last I tried to activate the Marshlands Conservation Area I had an equipment malfunction and as such it was a β€œFailed Activation”.

Today I headed out to get the one that got away.

I set up (red dot on the map) and operated with my FT891 set at 30w , 40m EFHF and proceeded to give out contacts….

In one hour I had managed to make 23 contacts in Ontario, and the Eastern Parts of the USA.

In the β€œlearning part” of my activation I still have to find a way to carry more stuff and also make the kit lighter… It was a 4 km walk there and back (thats almost 2.5 miles to those of you south of the border) and to be honest I was really glad to get home and get my feet up.

I mentioned a few posts back about using some sort of trailer to carry the kit and today’s effort reinforces that thought….

Anyway I did have fun…. and if I worked you I hope you had fun as well….. If you don’t see our QSO today in your Hunters Log let me know and I’ll try to figure out why not…
