Re: Need help with software for Modular 40 meter CW transceiver from Aug 2016 QST
Richard Dodd
There is a groups.io group for this project (SoftwareControlledHamRadio). However, newer projects by the author have taken over the content.
I wrote my own firmware for the VFO and made it available to the group. I think the files have disappeared from the group files area. However, the PDF instructions are still there. The source for my firmware is here in github: https://github.com/rydodd/SCRadioSoftwareK4KRW I added quite a bit of functionality. A video demo is here: https://www.youtube.com/watch?v=cLA14vGqYcE Richard K4KRW

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.

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: http://www.arrl.org/files/file/QST%20Binaries/Mar2016/Purdum.zip N5IB

Re: Middle or End
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. 73 - Dave, K1SWL

Re: Need help with software for Modular 40 meter CW transceiver from Aug 2016 QST
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. ... Jerry Wysocki, KC9JXE

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. 73, Gary WB6OGD

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

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. Curt

Re: Middle or End

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. Curt wb8yyy

Doc, I've grown to really like end fed dipoles. They are a bit expensive, but they seem to always work well. Don, W9EBK

I am going to need HOA antennas for at least about 3 to 4 mo. I have 20 and 40 dipoles on hand that I can put in my attic under my standard composition shingles roof...or I could put up a backpacker 10/20/40 Endfedz up there. Any suggestions or observations? 72/73 Doc K5OSA

Need help with software for Modular 40 meter CW transceiver from Aug 2016 QST
N4DR
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 . 73, Marc N4DR
