What was old is new again

By: VA3QV
13 August 2024 at 16:51

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.

Testing out a β€œNewly built” antenna

By: VA3QV
9 August 2024 at 22:35

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 β€œTransportable/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 β€œissues” with its performance.

The Essential Portable HF Antenna: 100 Watt End Fed Half Wave Kit

By: kb9vbr
24 July 2024 at 12:03

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.

DudeTenna 100+ W EFHW Kit with 75ft Heavy Duty Antenna Wire.

How to build the Ham Radio Dude’s EFHW Kit: https://youtu.be/Y-ojVTQbszw
Tuning and adjusting the dudetenna: https://youtu.be/VvYtT-4UwqM

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.

Screenshot

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 β€˜good in the book.

2024 Museum Ships Weekend

By: VA3QV
3 June 2024 at 15:29

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 Museum and 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 β€œinverted 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 β€œWelcomed 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 β€œspur 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.

SS Keewatin will be on the air

By: VA3QV
27 May 2024 at 15:33

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 β€œmodern” equipment.

So for this event I will be operating from β€œalongside” 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 β€œAmerican 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.

This page will not be updated so check my QRZ page for last minute updates….

The operating plan is to be operating from the β€œAmerican 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.

This page will not be updated so check my QRZ page for last minute updates….

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

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

Wire antenna down

By: VA3QV
18 April 2024 at 15:20

Woke up this morning and after coffee went to the shack. Noticed that the signals were way down and I had no static showing on the meter… Went to the back yard and found 2 sections of green wire on the ground.

A short (25 foot) section still attached to the tuner and then the remainder of the wire laying across some tree branches then on the ground. This means that the break happened about 20 feet above the ground and after looking at the ends of the wire it was a clean cut/break.

No teeth marks on the wire so I’m thinking it as it happened in the tree it must of been the clean cut of a bird beak??? The support tree is not strong enough for someone to climb up 20 feet (or so) with a pair of side cutters so….

Anyway…. I’m heading off to the Kingston Antenna Parts store (some of you might of heard of Princess Auto) and pick up a roll of 18 gauge green insulated wire and try and hide it in the tree this weekend. If successful I will be back on the lower bands and if not then its 10m to 20m for a while.

This could be an issue with my plans for several radio events this coming weekend.

Lets see how this plays out

ps… I do have an EFHW I could put out as a temporary antenna but would have to take it down when not using it so….

Your ultimate guide to the CaHRtenna Apollo End Fed Half Wave EFHW Antenna

By: kb9vbr
10 November 2023 at 13:18

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.
