Hint: For best CW performance, connect your paddles to a serial port using the
following table to make the connections.

4 (DTR) Common
6 (DSR) Dot
8 (CTS) Dash
* Assumes a 9-Pin connector
2. In the Options section, check Iambic for Iambic mode or leave unchecked for a straight key. If the
paddles seem reversed, check Rev. Paddle. The Semi Break In option allows the radio to be put
into transmit mode simply with detection of keyer input. Set Delay to the amount of time between
the last detected input and when the radio will switch back to receive (This should preferably be set
higher than 250ms).
3. Select the settings for CW Pitch, Weight and Ramp as desired (refer to the Keyer Sub-Tab section
of the preceding Setup Form chapter for more detail).
4. If not using Semi Break In, click MOX (16) on the Front Console and begin transmitting using
your paddles. If using Semi Break In (8), simply begin transmitting to key the radio. If using
Iambic mode, adjust the speed with CW Speed (8) on the Front Console. If Disable Monitor is
unchecked, you should hear the side tone. Verify with the TX Meter (4) set to Fwd Pwr that there
is forward power.
5. You are now ready to begin a QSO. If a 50 ohm dummy load was connected, connect an antenna in
its place. Tune to the desired frequency using one of the methods outlined in the Tuning Methods
section above. Select either CWL or CWU (6) and proceed with the QSO.
External Keyer
1. If you have your external keyer connected to a COM port, set the Primary Connection to this
COM port. Set the Primary Connection to SDR if you have your external keyer connected to the
SDR keyer input plug (see preceding Plug Pin-Outs chapter).
Hint: For best CW performance, connect your external keyer to a serial port.
See the table above on how to make the connections.
2. In the Options section, leave Iambic unchecked. If your external keyer seems reversed, check Rev.
Paddle. If using an external keyer with a sidetone, check the Disable Monitor checkbox to avoid
hearing the side tone from the internal keyer. The Semi Break In option allows the radio to be put
into transmit mode simply with detection of keyer input. Set Delay to the amount of time between
