TX Menu, CW Mode
To use a straight key, disable the Iambic control and enable Dot/Dash Swap in the Phone/CW
control panel in the Maestro Main Menu. Connect the straight key to the tip and sleeve of a 1/8
th
inch TRS plug and connect it to the Key input on the back panel of the Maestro. When Breakin is
enabled, the transmitter is engaged when the key contact is closed. When Breakin is disabled, the
transmitter must be engaged with one of the PTT inputs before using the key. The Delay slider in
the TX Menu sets the PTT hold time for a break-in in milliseconds. It can be set anywhere from
zero (full QSK), to 2000 milliseconds (2 seconds). See section 36.6.2, CW Mode Transmitter Control
Panel for details about these controls.
19.3 USING THE BUILT-IN KEYER
Maestro has a built-in iambic keyer that can be used either as iambic “A” or iambic “B”. Controls
for the keyer are found on the Phone/CW tab of the Maestro Main Menu. See section 33.9,
Phone/CW Tab for details about these controls.
The keyer speed can be set between 5 and 100 WPM using the Speed control (inner knob) on the
Transmitter multi-function control. The IAMBIC selector must be enabled to use the built-in keyer.
The Sidetone control will increase or decrease the Sidetone volume in the speakers and
headphones. Note that the sidetone button to the left of the slider should be illuminated to enable
sidetone output.
