If by any chance you live in South Texas check the attic many builders are using a foil backing on the roofing boards they put down to help with heat.
I used an end fed in an attic for over a year and worked all over Europe and some of Asia.

The article was actually in the March 2016 QST. It was the 49er with the DDS VFO.
The firmware can be found in the zipped folder posted on "QST in Depth" for that month:

Dave Benson
 

I'll echo Don's comment about the end-fed antennas.

I have the PAR 40M/30M end-fed and very happy with it.  It has a single trap about 45 feet out from the feedpoint, and an overall length of 54 feet.  I had no trouble setting the lengths for an SWR of 1.2:1 or better.  With that success, there's no need for an antenna tuner.  I've also built several end-feds for portable operation and had the same success with them.

The EF-10/20/40 is 40 feet in length, and could be bent at one end if you don't have enough attic length. Its maximum recommended power is 25 Watts if that's a concern.

You might try the ARRL website, for supplemental files from that QST article. I believe they had those supplements, even then. Or, look at the original QST article, print or online. Perhaps it is mentioned there, as a footnote at the end of the article. Either way, I hope you find it.

Either will radiate about the same, so it may came down to which is easier to install. The feedpoint of either antenna should be clear of nearby conductive objects of appreciable size.

Advantage of end fed half wave is usefulness on even harmonics.

Best hope you can install something that radiates, be careful if you encounter electrical wires up there as you install.

Do you have any trees?
I have been hanging vertical wires from them,
even attached right to the trunk for years.
Random length as long as possible and use
a Icom remote tuner.  Invisible to HOA and
XYL, all band, have worked the world with
100w ssb, though with sunspots 😀😀
Much better than anything inside.

Did you try the author, was this w8tee? Was this the rig that used the 49er board from far east? I assume you checked qst archives.

Need help with software for Modular 40 meter CW transceiver from Aug 2016 QST

I have the 40 meter Modular QRP CW transceiver from the August 2016 QST. Does anyone know where I can
find a copy of the firmware? It was working fine until I recently took it out of mothballs, only to find the software 
was corrupted and it did not work.
Thanks in advance for any help .

Re: Ozarkcon 2021

John C. Demuth - K8CQA
 

I will mark that date on my calendar and will try to "attend".  I've wanted to attend one of these in person, but have found it difficult to get away that long, as I am caregiver for my wife of 55 years.  So sorry the in-person event had to be cancelled again, but it is probably best for all of us.  Jane and I have nearly completed the on-line course in learning to be hermits! Since March 1 she has only left the house for necessary medical appointments.  I make fast trips through a grocery store with a list arranged in the order of the store's layout; I try to minimize my exposure so I don't bring any bad cooties home to Jane, who is so susceptible to disease (and allergic to flu shots). A virtual event would be perfect, especially being able to plan for the date this far in advance.
Canton OH Chapter 21, QCWA, has been having weekly informal gatherings via ZOOM; they are a great wAy to get together.  We have a number of members join in who cannot normally attend due to distance.
After many years, Jane got her license (KC8IEE). She understands the need for an occasional key, etc.. I try to reciprocate by honoring her desire for a new crockpot or toaster oven, etc., occasionally.  This has worked for us for 55+ years!
I am looking forward to seeing you on April 10!

Hello Mike
Yes! 
I would appreciate you help very much.
I am a ver inexperienced Zoom user.
I’m assuming we will use zoom 
For Webinar and will need to buy a user license.
The club will take care of this, Ron our treasurer has some Money.

I have been looking at the GQRP model from last year.

I’m lining up speakers and will ask them to “record” their presentations.

Do I need to have them do any thing 
Other than that?

Thank you very much Mike
I’m sure we will visit more in the near future!

Good Evening Group 

Well I was hoping that I would not have to make this announcement, but due 
to the continued spread of Covid and the delays that have been encountered getting the vaccinations 
rolled out, we have decided to Cancel the in Person Ozarkcon for 2021,
that would have been in Branson, Mo. 

But, as an old saying goes, when you get handed Lemons, make Lemonade?

Well this is not exactly Lemonade but something a whole lot better!

We're planning to host a Virtual Ozarkcon via one of the social media platforms and disturbed via the World wide Web.
It will be very similar in format to the in person Ozarkcon 
except we will be able to view it from the safety of our homes. 

The Virtual Ozarkcon is planned for the Second weekend of April, on Saturday the 10th of April. We moved it forward a week since Easter weekend is the 3rd and 4th. 

We're working on the details and more details will be posted as soon as they are available. 

We will have a great lineup of speakers with a wide variety of Qrp presentations for you to enjoy. 
We plan to have a Wackey Key contest, with Video clips to be submitted online, as well as
the long standing and very popular Home Brew contest. 

We have decided to hold off on the Buildathon this year since we can't be in the same room together.
Who doesn't enjoy the smell of Melted solder and burning rosin?

We haven't decided if we will have the K0N ops on the air but we will let you know. 

Anyway, that's all I have for now. 
So stay tuned for updates as they are available. 

72, 73 
Stay healthy and I will see you all at the 2021 Virtual Ozarkcon.
