Much ham band Morse makes use of a "code shorthand".  This is practiced by virtually all hams.

For example, the following is typical of what you might copy. "hrd ur call es gave shout - ur sigs 579
hr".  That brief copy really means "I heard you calling so I answered you.  Your signals are 5 read-
ability, 7 strength an 9 tone here."

Morse code is like learning a foreign language.  The more you use it the more proficient you be-

come.  If you learn the Morse code and then fail to use it, you will have to work at attaining your
prior level of proficiency by practice and use.

LEARNING TO SEND MORSE CODE

No  mention  has  been  made  about  learning  to  send  Morse  code.    Sending  is  much  easier  to

learn.  Your sending should try to duplicate the way the characters are presented by the BT-1.

The recommended means of learning how to send in the past has always started with a hand

key.    However  some  people  just  cannot  seem  to  operate  a  hand  key  proficiently  no  matter  how
hard  they  try.    People  who  have  gone  directly  to  a  Morse  electronic  keyer  and  paddle  set  have
done so well, that previous opinions about starting with a hand key are in serious question.

Regardless  of  the  type  key  or  keyer  used,  it  is  very  important  that  the  student  develop  the

proper sending rhythm so that his fist is easily read by other stations on the air.  A good fist and op-
erating practices can make more difference than an expensive transmitter and antenna system for
establishing contacts and adverse conditions.

AEA is noted for manufacturing the world's most sophisticated line of self-contained computer-

ized Morse code keyers that are simple to operate and low in cost.  We also manufacture the MBA-
RO code reader that is an excellent device for correcting and improving one's fist.  Even skilled CW
operators find they can improve their spacing of characters and words tremendously through the
use of an MBA-RO which serves as an impartial judge in monitoring one's sending.  More informa-
tion on the MBA-RO and our keyers is available in the current AEA Product Catalog.
