Transmitter Tuning
. To allow transmitter tuning, the keyer output transistors will be operated
upon pressing
. The
key must be released before the keypad tone is completed.
Tuning will be terminated by pressing any pad button or touching the dot or dash key paddle.
The tune feature only operates in the keyer-memory send mode.

Mistakes
. Incomplete, undesired entries may be terminated by pressing
. Unacceptable en-
tries will be ignored. For example, if a speed change were entered
, the result will be
no speed change.
III. Memory Operations
1.
Memory Locations
. The AEA CK-1 has ten separate, variable length memory locations. The
total memory length is about 500 characters (the actual length is dependent on the length of the
characters, the length and number of pauses, etc.), which may be divided into the ten locations
in any fashion. Each memory location length is automatically adjusted during message loading.
2.
Memory Message Load
. Two methods of memory loading are available, Real Time loading
and Automatic character and word space loading. In both modes memory loading does not be-
gin until the first character is started. This prevents the undesirable pause at the beginning of
the message playback. Messages may also be loaded in semi-automatic (bug) mode.
Real Time Memory Loading. To select Real Time loading, set the mode switch to Memory
Load (toward the connector panel) and press
. Select the message location desired, 0
through 9, and press the location digit. Memory loading will begin with the first character and all
pauses in sending will be loaded as sent (pauses use memory space). When message loading
is complete, press
to terminate the message load.
Automatic Memory Loading. The keyer is set to automatic memory load on turn-on. If real-
time load has been selected, automatic memory load may be re-selected by pressing
when the mode switch is in the memory load position.
In automatic message loading, a pause in sending longer than two space lengths records a
character space (three intra character spaces). If the pause is longer than five space length, a
word space is recorded (seven intra character spaces), loading then stops until the next charac-
ter is started.
To record a message, set the mode switch to LOAD, press the message location digit, key in
the message and terminate the message with the pound sign key .
Example: To store a message in memory location 5, set the mode switch to LOAD and press 5.
Now enter the message with the key. IMPORTANT: After the message is entered press
to
signal the end of the message.
3.
Memory Erase
. Power is supplied to the memory from the 12 V source. Operation of the off-
switch erases the entire memory, however the unit is designed to be left on continuously. To
erase one of the memory locations, switch to Memory Load (toward the connector panel), press
the location number and then
. The entire message in that location will be erased.
Example: Erase messages 3 and 7, set mode to Memory Load, press
or
.
4.
Memory Retention
. When 12 V power is first applied the memory will contain random char-
acters. These random characters should be erased (see previous section) before high speed
loading is attempted.
