Configuration Menu #2
1:PdlTone – Paddle Only Sidetone Enable
Some operators only want to hear sidetone that is entered on the paddles and not when using the keyboard.
When PdlTone is enabled, only the paddle will generate sidetone.
2:PdlSwap - Swap Paddles
As a convenience, the paddle operation can be changed. Normally dits are assigned to the left paddle and
dahs to the right. When swap is enabled, dahs are assigned to the left paddle and dits to the right. This
assumes that the left paddle is connected to the tip of the paddle connector and right to ring.
3:PdlMute - Paddle Enable (Muting) Control
To prevent unwanted paddle entry, the paddle can be turned off with this setting.
4:OutPort - Modify Output Port
K45's keying port connector can be configured in four different ways. The K45 can key one radio if PTT is
required or two if PTT is not required. In addition, the transmit output can be turned off (Mute) if you want to
use the K45 for CW practice and prevent transmitter keying. Sidetone is still active when transmit is muted.
The up/down arrows will cycle through four options which are:
1)
Select Port 1: Tip Output = Key
2)
Select Port 1: Tip Output = Key
3)
Select Port 2: Tip Output Off
4)
Transmit output muted
5:PTT Lead - Set PTT Lead-In Delay Time (0-99)
Lead In is entered as a two-digit number which sets the delay in 10's of milliseconds.
For example, if Lead-In is set to 26 the delay will be 260 milliseconds. The maximum delay that can be set is
99 or 990 milliseconds.
6:PTT Tail - Set PTT Off Delay Time (0-99)
Specifies the delay from the end of CW transmission to PTT de-assertion. This is set in units of 10 mSecs.

7:Tune 50% - Set Keying Duty Cycle for Tune Mode
Some Ops prefer to use a 50% duty cycle when keying their transmitter for tuning purposes. This reduces
the power dissipation in the transmitter final and can contribute to a longer transmitter life.
8:KeyrType - Select Paddle Mode
The K45 supports six keying modes: Iambic A, Iambic B, three Ultimatic versions, and Straight key. In
Iambic and Ultimatic mode the K45 makes dits and dahs automatically based on which paddle you press. In
