People who know me have heard me say that after all these years there are 3 radios I have sold that I actually regret selling. Well now there are only 2 radios that I regret selling…

Welcome the Xiegu X5105 back into my portable shack…
.
Between my FT991a and my FT891 there was a bit of a gap. The Yeasu FT891 Portable Station was a bit too heavy for my old bones. I needed something in a lighter backpack to make it easier to carry if I was to choose to activate one of the local POTA Parks here in Kingston.
The above pic shows my old X5105 with the Bandspringer attached
The Xiegu X5105 fills that gap. With the built in battery pack, the built in automatic antenna tuner along with the contest keyer and the built in CW Decoder it makes it a dream portable station.
My antennas are a 40m EFHW made with 28ga wire and a QRP AMAZON 49:1 unun. I also can use a 29foot end fed random wire using a QRP EARCHI 9:1 unun.
I also have the SOTABeams Bandspringer antenna that plugs right into the antenna input and uses the built in tuner to operate between 10m and 60m.
So what’s the other two radios you might ask?
Above is my first QRP setup. FT817, LDG QRP Autotuner.
If I could work a deal for a Yaesu FT817 and a Flex 1500 it would complete the list. However used rigs are pricy and it seems most hams think that radios seem to appreciate with age so like I mentioned above it has to be a good deal for both the seller and myself.

Last night around 9pm I was browsing Amazon and found the same 64:1 unun that I use with my 40m EFHW. This antenna is my primary antenna for my “Transportable/POTA” setup with my FT891.
I decided that the last one worked so well for me that it was time to see if the 1st one was the real deal or a fluke.
Around noon today I checked my front door and found the Amazon Fairy had magically made the new 64:1 unun appear sometime between 10am (last time I checked for it) and noon.
I had a spare 100 foot roll of Princess Auto 18ga insulated wire in the shack and as a bonus for my home environment is was even green.
I quickly measured out 64 feet and then did the connection things. As with most of Eastern North America it was a rather wet day.
Around 4pm locally the rain stopped and I was able to remove the old wire and install the new antenna, once again using the fir trees on the edge of my yard for camo as not draw attention to the antenna.
The SWR is pretty good especially for a wire hidden in the branches:
6m – 2.5:1, 10m – 1.7:1, 12m- 1.2:2, 15m – 1.6:1
20m – 2.0:1, 40m – 1.3:1, 80m – 3.0:1
The bands are not the best, but signal reports (90w output pwr) were fairly well (S7-S9+) with the stations that I was able to contact.
All in all for what it is…. I’m impressed and the best part is that using the built in auto tuner on my Yaesu FT991a I can easily bring it down to 1:1 on all the bands listed above.
The results are the same on my Yaesu FT891 with the same style of balun and a 64 foot length of quality (Red) Princess Auto 18 ga automotive wire. The only real difference is that as I use the 891 with no tuner I have to be careful on some of the bands.
As the new install gets more use I will let you know if there are any “issues” with its performance.

Ham Radio Dude’s portable end fed half wave antenna, the Dudetenna, features a substantial toroid and reinforced radiating wire for 100 watt operation in both digital and sideband modes.
The dudetenna end fed half wave, like other end fed kits on the market is pretty similar to the others in construction and performance. I;ve always said that an end fed is an end fed and all the models on the market and going to work pretty much the same. But there are a couple of key differences in this antenna that set it apart.
First off, the Dudetenna uses a different toroid than the others. Most end feds that are capable of 100 watt transmit power will commonly use the T140-43 toroid. This antenna is different and its transformer is built around this larger Fair-rite 43 mix toroid. The bigger toroid has about three times the mass of the T140, giving you greater permeability and slightly more bandwidth. With a bigger toroid, it should handle a full 100 watts sideband without overheating.
The other two notable features are the use of an SO-239 or UHF female connection instead of a BNC, so no adapter will be required if your coax has PL-259s and finally, the kit comes with 75 feet of vectron fiber reinforced wire. Vectron fiber, much like Kevlar, will not stretch or break, giving your radiator wire greater mechanical strength for use out in the field.
The kit is also available with or without the wire, so you can build the transformer and then supply your own wire. It’s your choice.
Ham Radio Dude did send me a Dudetenna end fed half wave antenna kit to build and put on the air in exchange for a video. But my opinions are my own and there is no outside influence. So let’s head inside, build this antenna, and then put it on the air.
As a bonus, patrons can view an hour long video of me assembling the Dudetenna end fed half wave. Visit my page on Patreon for details: https://www.patreon.com/kb9vbrantennas
I do return QSL, if you made a contact with me and would like a QSL, please send me one. Return postage not necessary, but always appreciated. As they say, KB9VBR is ‘good in the book.

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.
It’s a POTA road trip! I head out to activate three new to me parks while using a different antenna at each one. Ride along with me for an epic Parks on the Air activation as we find out which one will be the best
As a bonus, patrons can view the full, unedited phone contacts for this Parks on the Air activation. Visit my page on Patreon for details: https://www.patreon.com/kb9vbrantennas
I do return QSL, if you made a contact with me and would like a QSL, please send me one. Return postage not necessary, but always appreciated. As they say, KB9VBR is ‘good in the book.
Watch me, in real time, as I deploy an end fed half wave antenna, set up my station on a picnic table, and do a QRP (5 watt) POTA activation on the 15 meter band.
I head to Council Grounds State Park (POTA K-1447) to test the new Chameleon LEFS 4010 end fed half wave antenna system. The LEFS or Light Weight Antenna System is a versatile EFHW HF antenna with tuner-free operation on 40, 20, 15, and 10 meters and can be used with a tuner on 60, 30, 17, and 12 meters. This lightweight antenna is specially good for low power, or QRP, operation and is small enough to be carried in your pack for portable POTA and SOTA adventures.
I take a look at the Coffee and Ham Radio’s Apollo End Fed Half Wave (EFHW) antenna. CaHRtenna EFHW is a 49:1 end fed antenna designed to operate on the 40 to 10 meter bands.
The god Apollo is one of the most important in Greek Mythology and is also the name of the Coffee and Ham Radio’s flagship product, their end fed half wave antenna. The coffee and ham radio guys sent me one of their antennas to build, so let’s put it together and get it on the air.
Apollo is the greek god of light. Also archery, truth, and poetry. These are some pretty lofty goals to attach a name to an end fed half wave antenna. But I have a feeling the Coffee and Ham Radio’s Apollo antenna will live up to those expectations.
The coffee and ham radio’s Apollo antenna is available online for purchase direct from them. They did send me this antenna in exchange for one of my 2 meter J-Pole antennas and a review, but my opinions are my own. This antenna comes as a kit, so you will have to assemble it before putting it on the air. All the parts are included, with the exception of some basic tools,
So let’s head to the bench, unbox the Apollo antenna, assemble it, and give it a test.
