How Bob Sees “Pounding Brass”

*We have left some things out because we didn’t remember them

*Redundancy is good so you will hear some things twice

*The alphabet and numbers*= dah di di di dah* -•••- double dash frequently

used to separate thoughts

*. di dah di dah di dah* •-•-•- Period

*, dah dah di di dah dah* --••-- Comma

*? di di dah dah di di* ••--•• Question mark

* Letter abbreviations for the numbers:* 1 A* 2 U* 3 V* 5 E* 7 B* 8 D* 9 N* 0 T* You will see the N and T

more frequently than the others

*The period of a single di is one unit*The period of a single dah is three units*A period of one unit separates each element, di or

dah*A period of three units separates each character

within a word. A period of seven units separates each word.*For purposes of specifying code speed, the

“PARIS” 50-unit standard is used. From that standard, the following relationship is derived: u=1.2/c where:*U = period of one unit, in seconds*C = speed of transmission, in words per minute

* 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 while learning 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.

*At speeds below 18 WPM, characters are sent using 18-WPM timing, but with extra delay added between characters and words to produce an overall lower speed.*Speeds are specified as s/c, where s is the

overall transmission speed and c is character speed. For example, a 5-WPM transmission sent with 18-WPM characters is specified as 5/18 speed.*The adjustment to a lower speed is made by

adding delay between characters and words. The added delays are constant for a given Farnsworth speed and will maintain the 3/7 ration of character space to word space.

* Learn the sounds of the letters, don’t memorize di’s and dah’s

* Eventually you may learn the sound of entire words* Listen to a lot of code practice*Don’t try to send any code until you can maintain solid

copy of “well sent” code* If you haven’t learned what “well sent” code sounds

like, you can’t send well either.* There is lots of crappy code on the air

* Some operators don’t know what good code sounds like* Others are trying to use keyers and can’t get the timing

correct

*Use a straight key first, leave the fancy stuff for later

*That’s enough - give the other guy a break and quit sending. No one wants to hear this over and over if they are waiting to reply.
