MFJ-464 Instruction Manual CW Keyer/Reader
6
Basic Operation
The MFJ-464 is simple to operate. The Power button controls power to the unit. Start sending
with a paddle or keyboard. Adjust the volume and speed to your preference. If the speed is still
too fast or too slow, adjust the speed using the Set dial control.
All characters or code sent by the user are played on the sidetone speaker. This allows the user
to hear what he is keying, typing, or sending with a computer. Only when the keyer is used with
a paddle is the code sent as soon as it is keyed. When using a keyboard or keyer terminal, you
may type ahead of the code that is being transmitted. This allows you to enter words and phrases
faster than the transmitted code. This permits smoother code with less pauses because you can
fix misspelled words and think of the right phrase to use while your previous sentence is being
sent.
When you are in command mode, memory save, or configuration mode, the code sent to the
speaker is not sent to the Keying Output or your radio. This keeps all erroneous code off of the
air.
