Field Day 2024 will be starting in 3 hours. In previous posts I had mentioned that I was either going to be operating as a 1B station or a 1D stations depending on the weather. “Mother Nature” helped me make the choiceand its not nice (or smart) to argue with Mother.
The choice is “1D” and if you read the following from The Weather Network you will see why.
Kingston, ON
Special Weather Statement
Issued at Sat 8:59 AM Jun. 22
Issued by: Environment and Climate Change Canada
Description: Significant rainfall possible this afternoon into Sunday.
Hazard: Rainfall amounts of 30 to 50 mm. Locally higher amounts possible.
Timing: This afternoon into Sunday.
Discussion: The potential exists for multiple rounds of showers and thunderstorms this afternoon into Sunday. Local amounts exceeding 50 mm are possible. A rainfall warning may be required for some areas.
For information concerning flooding, please consult your local Conservation Authority or Ontario Ministry of Natural Resources and Forestry office. Visit Ontario.ca/floods for the latest details.
Heavy downpours can cause flash floods and water pooling on roads.
Watch for possible washouts near rivers, creeks and culverts.
###
So there you have it….
Setting up in a Park to operate 1B in a Monsoon is one way to ruin my almost new FT891 seeing that as a general rule they don’t like water.
And to be honest it would not be fun for me either.
I still will be participating and hope to give out the rare exchange of 1D ONE to as many stations I can contact during the event. At home I have the chance to operate VHF, 6m, and the HF Bands that the Field Day rules allow.

The event was held on June 1st and finished on June 2nd. At the time of posting this there were 106 Museum Ships (including memorials) on the list. For more info on the event check out: https://www.nj2bb.org/museum/ .
In Kingston we were fortunate enough to have the SS Keewatin berthed at the Great Lakes Museumand so for this event it was a 45 min bus ride with all the radio gear I needed to participate.
Here is a couple of pics I took while at the museum.
The gear I used for operating from alongside the Keewatin was my POTA Station that consisted of my Yaesu FT891, Eco-Worthy 20ah LIPO 4 battery and a MFJ 33 foot telescopic mast to support the home brewed 63 Foot End Fed Half Wave (10m to 40m) antenna.
It looks rather small compared to the size of the Keewatin… Thanks to the Taxi Driver who moved into the pic so I could show the size of the ship easier. No I did not use the taxi… Kingston Transit bus #3 stops right at the front door of the Museum.
All my gear fit in my wife’s laundry cart… She may never get it back now…
I used some bungy cords to secure the mast (right of the pic) to a fence behind the tree cover. It suspended the EFHW in a “inverted Vee” configuration and worked well for me with no tuner needed.
I was able to operate for about 3 hours (or less) each day. The gear worked without a hitch but not so much the operator.
As the radio room in the Keewatin has not been updated yet, I was forced to operate from alongside (the above pic) so I was unable to leave the gear to use the facilities and so once nature called… it was time to pack up.
At the end of the event according to my logs I actually was contacted by 100 stations that were “Welcomed on Board the Keewatin”… of those 100 contacts 12 of them were other Museum Ship and their details follow.
(Pictures above the name of the ship)
Col James M Schoonmaker
USS Lafferty
USS Thresher Memorial
USS Massachusetts
Tall Ship Elissa
USS Nautilus
Claud W Somers
USS North Carolina
Watson Naval Museum
USS Salem
USS Cobia
This was a “spur of the moment” style of activation. I was going past the ship a week before and then found out the Museum Ships event was the next weekend. Although the Keewatin does have a valid Callsign without the radio room ship shape they were not in a position to activate.
I asked if I could do it and was given the green light to operate (using my own personal callsign) from where I did. (alongside but outside the fence)
As the Drydock is part of the Great Lakes Waterfront Trail (POTA CA-6003) some amateurs also got a new park in their logs.
Long story short… The activation was a success…. At least 100 amateurs now know of our ship and the Museum Ship community welcomed the Keewatin and its my hope that next year the ship itself will the on the air.
If we made the contact, thanks again. My logs for the two day event have been uploaded to EQSL, QRZ.com, the Museum Ships Group and will be uploaded to LoTW when they have fixed the security issue. I will also offer a copy of my logs to the Keewatin Radio Operators (see above link) for their records.
The lastest (and largest) addition to the Great Lakes Museum collection in Kingston Ontario is the SS Keewatin.
I took this pic Saturday May 25 just before the Museum opened the exhibit.
Its new home is in the Kingston Drydock which is on the shore of Lake Ontario and its history goes back before Canada’s Confederation.
The above shows the Keewatin in the Drydock over the winter. Thanks to Google Maps and Doug Knutson for the Graphics.
Now on the the Radio Part of this….
This coming weekend is the Museum Ships Weekend event (June 1st and 2nd) and the Keewatin will be on the air for this event and we are in really good company.

And as you can see we will be in pretty impressive company…
Now the only issue with this (the first) activation of the new museum ship is that the passenger areas of the ship are open to the public but the Radio Operators Room is still waiting for some period equipment to be set up as a display. So until that is done we can’t install as we don’t know how much room there will be for the “modern” equipment.
So for this event I will be operating from “alongside” the ship (see below pic)
The Radio I use for this event will be my POTA Station gear which is a Yaesu FT891 along with a 40m (64:1 unun) EFHW supported by a 33 foot MFJ Telescopic mast. Backup antenna will be a 17.5 foot vertical (using same mast) fed by a 9:1 unun with a single raised counterpoise.
The operating plan is to be operating from the “American General” parts of the different bands. Hoping that 20m and 40m will be good for us but we have the equipment to operate from 6m to 40m
I hope to start operating at 1300 (UTC) and run till the 20ah battery dies out ( or darkness arrives) on both days.
Will be operating as VA3QV and will uploading logs to LoTW, EQSL and QRZ.com.

If you went to the Smith Falls Hamfest hope you had fun… I’ve got a 2m halo antenna (for my 991a) and a 9:1 unun (yes another one) being delivered later today as I was unable to make it there. More details on the new toys after I get to test them out
AFTERTHOUGHT: Not sure if EARCHI is still offering the unun but the website is still up so perhaps would be better to email them first before you send funds.
The weather this weekend was not nice enough (for me) to seriously consider taking the Portable Station out any of the local POTA Parks as I had previously mentioned. Although the temps were above the freezing mark I find the cold harsher now and it was a bit too cold for me to be sitting at a picnic table.
Now it was not as bad as the above but it sure felt like it so…
So my Plan “B” was to just operate from the shack and give out contacts….
So starting on Saturday (0000hrs utc) I started spinning the dial and giving out contacts to whoever I could hear in whatever contest/event they were participating in. Contacts were made in the following contests/event:
POTA Support Your Parks, Ontario QSO Party, Michigan QSO Party, Nebraska QSO Party and the Quebec QSO Party. A few Special Event Stations were also in the log as well.
All the contacts were given a 5/9 ON exchange with the Ontario QP Participants getting a “5/9 FRO (Frontenac County)”.
I managed to give out 40 OQP exchanges .
The POTA activators were really busy and I found (in some cases) hard to break the pileups. That part of our hobby is growing in leaps and bounds. I hope that some of the newer operators were not discouraged by the sheer numbers of stations calling.
According to my records I managed to raise my Unique Parks worked count to 2565 logged. Slowly heading towards the 3000 mark which is my next goal.
With the promises (would the Weather Person lie to me?) of better (warmer/dryer) weather in the next week I am still planning to give the Portable station’s new 17 1/2 foot vertical a testing out from the field. Don’t know which day (yet) as the band conditions have to cooperate along with a bit warmer weather from “Mother Nature”
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 “Imitation” 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 “Coastal-20” antenna that I use at home for 10-12-15-17 & 20m. If you “Google 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…
One of the things on my “to do” list was swap out the 17.5 foot vertical wire on my Modified “Coastal 20” antenna with a 29 foot vertical wire.
I did the swap and then came back to the shack to do the SWR testing and also see where I was being heard and what I was hearing….
First issue found is that I no longer able to tune up on 40m using the built in tuner in my Yaesu FT991a….
On 10-12-15-17-20m it seemed to tune up quicker (2nd issue)but I did notice that I also had to tune up more often as I was searching and pouncing. On the plus side the signal reports I was given (after asking for an honest report as I was testing the antenna) seemed what I was expecting between S7 and S9. I was hearing most stations with no problems…
After careful consideration I decided to swap the 29 foot wire out and bring the 17.5 foot wire back. The reasoning for this was as I do a lot of S & P at home, I prefer not to have to re tune constantly…
And for the record the shorter wire is working exactly as well as it was working before I tried to improve things… There could be a lesson to be learned here…
To those who are participating in the CQ WW WPX Contest good luck and have fun.
I’ve been doing some antenna modelling and comparisons for John, W2VP comparing some phased and parasitic arrays. One of the phased arrays I modelled was an End-Fed-Half-Wave (EFHW) phased vertical array for the 40m band. It’s got such a nice radiation pattern that I thought I’d add it to my antenna pages here on the website for others to read too.
M0AWS 40m Band EFHW Phased Vertical Array Antenna View
The EFHW Vertical Phased Array is as simple as two vertical half wave wires both of which are fed via their own 49:1 Unun. Wire 1 (radiator) is exactly 20m tall and wire 2 (reflector) is 21m tall. The space between them is exactly 10.5m.
This simple antenna arrangement gives a surprisingly good radiation pattern with a reasonable forward gain and front-to-back (FB) ratio.
M0AWS 40m Band EFHW Phased Vertical Array 3D Far Field Plot
The antenna has quite a wide beam width which is to be expected from a pair of phased verticals. The nice thing about this array is that it has very little in the way of high angle radiation. This makes this antenna ideal for long distance communications. This isn’t an antenna for local chatter!
M0AWS 40m Band EFHW Phased Vertical Array 2D Far Field Plot
The 2D Far Field Plot shows that the antenna has a forward gain of 3.16dBi at 19 degrees. This is some 8 degrees lower than a typical 1/4 wave vertical phased array. The array also has a very respectable front-to-back (FB) ratio of 20.53dB.
Both elements in the array will need to be fed via individual 49:1 Ununs with the reflector requiring a feed phase angle of 100 degrees. A 100 degree phase angle gives better performance than the typical 90 degree phase angle that is typically used for 1/4 wave arrays.
For such a simple design this antenna should give great DX results as long as you have the necessary supports for the two vertical wires and the space for the guy lines. If only my garden was much bigger and I had some large trees to hand!
Summary:
Radiator (Element 1): 20m Reflector (Element 2): 21m Reflector Feed Phase Angle: 100 Deg Wire Dia: 4mm Feed Type: 49:1 Unun on each vertical element and a phasing harness Impedance: 50 Ohm SWR: <1.5:1 across whole band
