All amateurs are familiar with CW operation. However, there are some differences be-
tween manual and automatic Morse operation. As a rule, computer-based Morse needs
stronger signals in order to achieve the lowest number of errors in automatic decoding of
the received test. Computers are not forgiving or tolerant of a "bad fist"! Trying to decode
poorly sent Morse Code with any computer system is like the "GIGO" rule – Garbage In,
Garbage Out! The best computers will send garbled characters to the screen or printer
when trying to decipher CW in which the dot-dash lengths, intervals and ratios, inter-char-
acter and inter-word spacing are really out of the normal specifications.
Don't expect your PK-232 to do miracles and produce good copy from bad fists! Later in
the manual you'll learn how to use the PK-232 program with your computer to improve
your own CW fist.

MSPEED
The number you enter becomes the new transmit speed and replaces the value previously
stored in the program. The slowest available Morse speed is 5 words per minute. If you
enter numbers lower than 5, the program uses 5 words per minute.
For speeds from 5 to 14 words per minute, the transmitted code is sent in Farnsworth
spacing; the characters are sent at 15 words per minute while the spaces between char-
acters are lengthened to yield an overall code transmission rate of 5 to 14 words per mi-
nute.

The LOCK command locks the system to the speed of the received signal. Reception of
Morse code in the presence of noise can be enhanced this way. To unlock the speed, type
