Farnsworth Method
Locked
 
|
The ARRL has been using the Farnsworth Method for at
least 40 years and probably has been using it longer than that. The US Army used the Farnsworth Method during WWII. I have not been able to find out who old Farnsworth was, but my guess is he was an operator about 1910 when the Bug got popular and he needed to train someone and wanted to use his bug. But that is just a guess. I have been a ham since 1956, but I don't remember getting interested in the Farnsworth Method until about 1975 when I was studying for my Extra and teaching code classes. It was the generally accepted method in 1975 and I as far as I can find out still has very few that differ in opinion.

Farnsworth timing
Traditionally, reducing the speed of Morse code has been done by making everything take longer, i.e. both the sounds and the silent periods between them. Using Farnsworth timing, characters are sent at the same speed as at higher speeds, while extra spacing is inserted between characters and words to slow the transmission down. The advantage of this is that you get used to recognizing characters at a higher speed, and thus it will be easier to increase the speed later on. Using Farnsworth timing is optional in Just Learn Morse Code. The ARRL uses Farnsworth timing for transmissions, practice and test tapes up to 18 WPM (90 CPM). Farnsworth timing was invented by Donald R. Farnsworth (W6TTB) in the late 1950s. -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of WILLIS COOKE Sent: Sunday, March 23, 2008 4:30 PM To: Elecraft Reflector Subject: [Elecraft] Farnsworth Method The ARRL has been using the Farnsworth Method for at least 40 years and probably has been using it longer than that.

B'Gosh and B'Golly! Don't know who "old Farnsworth" was? Philo T. Farnsworth was a Utah native who in 1927 got the first patent for the "image dissector" video camera tube which enabled television as we know it. RCA's Sarnoff stole it and the designation of "Inventor of TV" from him just as he - Sarnoff - stole FM radio from Major Edwin Armstrong but that's a different rant. Some of the FM and TV transmitters serving Salt Lake City are located on a mountaintop named Farnsworth Peak in his honor. He was born in 1906, entered Brigham Young University in 1920, and there is no indication in his biography that he was a radio operator, ham or otherwise. His electronic genius extended to other areas, primarily development of electronic devices. Just like Major Armstrong, his battle with Sarnoff's RCA took its toll on him, but it's been only the past few decades that his honor and achievements have been recognized for what they were. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

An interesting sidenote -- Sarnoff started making people call him "General Sarnoff" after WWII, during the final years of his legal battles with Armstrong, because he felt Armstrong being addressed as "Major Armstrong" imbued him with an unfair aura of honor and credibility. (Sarnoff had been granted a special commission as a Brigadier General during the war so he could serve as a communications consultant to General Eisenhower.)

"Russ" Farnsworth, also known by his call sign <http://en.wikipedia.org/wiki/Call_sign>, W6TTB, are taught to send and receive letters and other symbols at their full target speed, that is with normal relative timing of the dots, dashes and spaces within each symbol for that speed. Being Wikipedia, I don't know if it's true or not, of course.
