As this blog's faithful readers know, son Jesse recently published a book.   Somehow, his moving introduction to that book dealing with his  grandfather, also 
, garnered the attention of one Mr. Michael Carroll, creator and editor of an amateur radio memorial site called the National Silent Key Archive.  Mr. Carroll wrote to Jesse, as follows:
I invite you to set up a ham radio silent key memorial page for your     grand dad at the 
. Working with only the few bits of info     your provided in your article,     
I came up with two possible call signs for your grand dad.
W9IV and W4PQA. These two links will take you directly to each call     sign page respectively.
Once at the correct page, you can add photos, an obituary or     biography, and attach other documents, like copies of his license,     QSL card, or additional photos.
If neither of these call signs was your grand father's, I might be     able to dig a bit deeper if you provided a bit more info about your     grand father; location (QTH) and exact birth date, etc.
Thank you.
I  am replying to your thoughtful and accurate research report to my son,  Jesse (J.S.) McDougall, which he has forwarded to me.  Indeed, my Dad  was W9IV, formerly W9CVQ, back when he was operating from the Chicago  area, between 1948 and about 1987.
At my office I have, I believe, one of Mac's QSL cards,  If I can find it, I will scan it and send it to you.
I  am attaching a photo of Mac, and one of his grave marker.  Here is a  brief summary of my memories regarding Dad's long history in ham radio.   
Dugald Stewart "Mac"  McDougall
Born May  15, 1916, and raised in Indianapolis, Indiana, Mac's boyhood hobby was  building radios, which led to his learning Morse Code and getting an  amateur radio license in 1929, when he was 13 years old.  He held that  license continuously until his death at age 91, on September 15, 2007.   The son of George McDougall, a railroad freight agent, and Effie Barclay  McDougall, a high school math teacher, the precocious Mac entered the  University of Chicago at age 15, took a 6-year program that included  both undergraduate and law schools, and graduated in 1937, at age 21,  near the top of his law school class, with both a B.A. in history and a  J.D.
As a boy in  Wilmette, I used to sit in the basement next to Mac's workbench,  watching as he soldered and fiddled, modifying or repairing the surplus  WWII military radios that were then his  favorite toys.  Thus, I heard lots of stories. One  of the best stories Mac told about the effect of amateur radio on his  life had to do with his four years in the U. S. Navy during World War  II.  To the best of my memory, it went like this:
Shortly after Pearl Harbor, I volunteered for the Navy's Officer Candidate School.  ("Why the Navy, Daddy?")  My father had told me that the food was better in the Navy.
I  went through OCS, and on through Communications School, and was about  to graduate to the fleet, when an announcement appeared on the bulletin  board of an entrance exam for  something new, called Radar School.  Intrigued, I  asked my commanding officer whether I might sit for that exam.  He  explained, "I am sorry, Ensign McDougall, but the Navy's Radar School  (located in Cambridge, Massachusetts, at Harvard and MIT) is restricted  to electrical and electronic engineers, and I see you were a history  major."  I told him, "Sir, I have been a ham radio operator since I was  13, and I have built all my own radios.  I believe that I understand the  theory."  My commanding officer handed me a book, and said, "The exam  is in the morning.  I will add your name to the list."  
Mac  passed the entrance exam, completed radar school, then served about six  months at sea on a sub chaser, escorting convoys from Boston to  Halifax, Nova Scotia, where they joined more ships for the long and  hazardous  voyage to England or Russia.  Then, Mac commanded the Radar Repair  Squadron at the Charlestown (Mass.) Naval Base.  Thereafter, he was sent  back to the Radar School as an instructor.  
Hence,  in August of 1943, I was born at Chelsea (Mass.) Naval Hospital, where  my delivery and my mother's two-week hospital stay cost the family a  total of $37.50.  (Mac told me once that I was worth every penny of  that.)
The rest of  the story is that in 1944, the Navy's Bureau of Personnel (BUPERS)  ordered Mac, whom it had identified as a lawyer who knew radar, to move  to Washington, D.C. to serve in the Navy's Patent Department.  This move  led to Dad's long and distinguished postwar career as a patent and  trademark lawyer.  
In that career, Mac was a modest man.  We four sons  discovered only in 2012, almost five years after his death, this web page: 
http://www.barnesandnoble.com/c/dugald-s-mcdougall.  We'd  known that Dad spent a lot of time traveling to various federal courts,  but had no idea that during his career, Mac had argued some eleven  cases at the Supreme Court of the United States.
 
After  his retirement at age 70, Mac and Judy, our stepmother, made two trips  around the world, largely to visit his ham radio friends.  Mac had radio  friendships of some fifty years' duration in South Africa, New Zealand,  Australia, and in many other countries.  
When  his time to die was fast approaching, my wife Shirl and I visited Mac  in Haines City, Florida, and were discussing his final resting place  with him.  Shirl found Mac's Navy  discharge document, and we had gone up to Webster, FL to see the  National Cemetery there.  I told Mac that he had the right as a veteran  to have his ashes interred there, "With your fellow WWII veterans."  Mac  replied, "I wouldn't have any objection to that."  
So, that is where W9IV lies, in silence.
Mac  is survived by his wife Judy (Stephen) McDougall, and his four sons,  Dugald George, Duncan Carl, Walter Allan and Robert Stewart McDougall,  plus thirteen grandchildren and two great-grandchildren.  R.I.P., Dad.
Respectfully,
Duncan Carl McDougall
