Previous view 4 RECEIVE AND TRANSMIT Electronic keyer functions (Continued) DDKeyer set mode (Continued) Side Tone Level (Default: 50%) Select the CW sidetone output level. • 0 to 100% can be selected. Side Tone Level Limit (Default: ON) Set the CW sidetone level limit. When the [AF] (L) control is rotated above a specified level, the CW sidetone does not increase. • OFF: CW sidetone level is not limited. • ON: CW sidetone level is limited. Keyer Repeat Time (Default: 2sec) When sending CW using the repeat timer, set the time between transmissions. • 1 to 60 seconds in 1 second steps can be selected. Dot/Dash Ratio Set the dot/dash ratio. (Default: 1:1:3.0) • 1:1:2.8 to 1:1:4.5 (in 0.1 steps) can be selected. Keying weight example: Morse code "K" Weight setting: 1:1:3 (default) DOT (fixed*) DASH DASH Weight setting: Adjusted Adjustable range SPACE (fixed*) *SPACE and DOT length can be adjusted on the Key Speed/CW pitch adjustment display. Rise Time (Default: 4ms) Set the rise time of the transmitted CW envelope. • 2, 4, 6 or 8 milliseconds can be selected. About rise time Key action Tx Rx Tx output power Set Tx power level 0 Rise time Time Key clicks on nearby frequencies can be generated if the rise time of a CW waveform is too short. Paddle Polarity Set the paddle polarity. (Default: NORMAL) • Normal or reverse polarity can be selected. Keyer Type (Default: ELEC-KEY) Select the keyer type for [ELEC-KEY] connector on the controller. • Straight key, BUG-KEY or ELEC-KEY can be selected. Regardless of this setting, the [KEY] connector of the Main unit is for only a straight key. MIC Up/Down Keyer (Default: OFF) Set the microphone [UP]/[DN] switches to be used as a key. (The microphone [UP]/[DN] switches do not work as a "squeeze key.") • ON: The [UP]/[DN] switches can be used as a key for CW. • OFF: The [UP]/[DN] switches cannot be used as a key for CW. • When "ON" is selected, the frequency and memory channels cannot be changed using the [UP]/[DN] switches. • The optional HM-151 microphone cannot be used as a MIC Up/Down Keyer. 4-11
