 ## Keyers & audio
 
 - **CW keyer** with macros and F-key macros. The keyer engine is selectable:
-  **WinKeyer** (K1EL WK1/2/3 over a COM port), **Icom** (the radio's own keyer
-  over CI-V — no extra hardware, works over the remote link too) or **TCI**.

+  works over the remote link too) or **TCI**.
 - **Digital Voice Keyer** (DVK): record F1–F6 voice messages and transmit them.
 - **QSO audio recording:** continuous rolling capture; on *Log QSO* the contact
   is saved to a per-QSO WAV (`CALL_YYYYMMDD_HHMMSS.wav`); mixes RX + mic.
