Menu C
Semi-Auto On/Off (SA)
Use Semi-auto On/Off to toggle between semi-auto (bug) mode on and off. The keyer responds
with the current mode "ON" or "OFF". Semi-auto mode creates automatic dots but requires dashes
to be hand keyed. Note: Semi-Auto mode may not be used to enter messages, serial numbers or
in command mode.
Iambic On/Off (IA)
Use Iambic On/Off to toggle between iambic modes on and off. The keyer responds with the cur-
rent mode "ON" or "OFF". Iambic mode allows you to squeeze both paddles and get alternating
dashes or dots. Non-iambic mode does not alternate between dots and dashes during a squeeze.
It plays whatever side made contact first until it is released. See Iambic A or B.
Queue On/Off (QU)
Use Queue On/Off to toggle between queue mode on and off. The keyer responds with the current
mode "ON" or "OFF". Queue mode enables the user to load messages into a buffer to play sequen-
tially. In queue mode, if you press a memory button while a message is playing, that message will
play after the current message is done. In normal operation pressing a message memory will abort
any message being played and play the new message.
Sidetone On/Off (ST)
Use Sidetone On/Off to toggle between sidetone speaker on and off. The keyer responds with the
current mode "ON" or "OFF". If the sidetone is turned off, it will still play command messages and
status information.
Output On/Off (TX)
Use Output On/Off to toggle between output on and off. The keyer responds with the current
mode "ON" or "OFF". If the output is turned off, signals are not sent to the keyer's gridblock or di-
rect outputs allowing practice operation. The output is automatically disabled during memory mes-
sage storing, command mode operation, status information and keyer setup.
FCC Exam (FC)
FCC Exam sends a random QSO just like in a real exam. Copy a test in Morse and then check your
copy against what is on your keyer terminal screen.
