Set CW keying speed in WPM

Use the Speed slider in the Phone/CW applet to set how fast the radio keys CW, measured in words per minute. This controls the radio's internal keyer and affects paddle, straight-key, and CWX transmissions.

Before you start

  • AetherSDR must be connected to a FLEX-8600 radio.
  • The active slice must be in a CW mode. The Phone/CW applet shows the CW sub-panel only when the active slice is in CW mode; otherwise the Phone panel is displayed.
  • Open the Phone/CW applet by clicking the P/CW tray button in the right sidebar, or confirm it is already visible.

Steps

  1. Verify that the active slice is in a CW mode. The applet automatically switches to the CW sub-panel when CW mode is active.
  2. Locate the Speed (CW) slider in the CW sub-panel.
  3. Drag the Speed (CW) slider left to decrease WPM or right to increase WPM. The valid range is 5–100 WPM.

What each control does

Control Description Default
Speed (CW) Sets CW keying speed sent to the radio's internal keyer.

Tips

  • The Speed (CW) slider operates the radio's keyer speed. Changes take effect immediately and apply to the paddle, straight key, and any CWX text transmissions.
  • The Sidetone toggle and Sidetone volume slider control both the radio's DAX-fed monitor and the client-side low-latency sidetone in lockstep. Adjusting speed does not affect sidetone pitch; pitch always follows the radio's cw_pitch setting automatically.
  • The Level gauge appears immediately on connect when the mic source is set to PC, or when RADE mode is active. In both cases the gauge uses client-side metering and is not suppressed by the met_in_rx setting, even when not transmitting. When RADE mode is active, the gauge continues to show level during RX.
  • The Compression gauge reads 0 dB during RX. It only shows a non-zero value while the radio's interlock reports a TRANSMITTING state and the speech processor is enabled, preventing stale TX-chain readings from appearing during receive.
  • The Mic gain slider behaves differently when RADE mode is active: it acts as client-side RADE gain and stores its value under PcMicGain rather than sending a mic level command to the radio. This prevents silently overwriting the hardware mic setting. The same PcMicGain setting is shared between PC source mode and RADE mode.
  • The Breakin toggle fully controls whether CW keyboard and MIDI key edges trigger TX. With Breakin on (QSK), key edges trigger TX and the break-in delay holds the relay. With Breakin off, keys are queued and you engage PTT manually. No automatic PTT envelope overrides this behavior.
