As I couldn’t find a suitable voice keyer for SmartSDR on Windows, I decided to develop my own.

Features

• works with local radios (LAN discovery) as well as via SmartLink

• option to auto connect to first radio

• 20 slots for recording (right click on slot for context menu)

• Auto MON on playback

• Using DAX (Device: FlexRadio Systems DAX TX) to send audio (DAX will be auto-enabled/disabled during playback)

• runs on Win 10/11 64bit

The software is 100% free of charge, no trialperiod or whatsoever. If you like it, a donation will be much appreciated!

 

Have fun with it

Release Notes:

Version 1.0.4

• added: local per-slot hotkeys alongside global hotkeys in the same dialog, with per-profile persistence and conflict detection

• added: focus-aware slot hotkey captions with English key names and tooltips showing both assignments

• added: per-slot auto-repeat with configurable total play count and pause, available through the repeat icon or Play repeat context menu

• added: dark pause state with a shrinking countdown bar between auto-repeat transmissions

• added: stop auto-repeat when operator PTT/MOX activates during a pause without releasing the operator’s transmission

• changed: clicking any slot or repeat icon stops active playback or auto-repeat, including pauses

• changed: repeat icon gray when unconfigured, blue when ready and green while the sequence is running

• added: optional per-slot peak normalization to -3 dBFS for PC/TX playback, capped at +12 dB gain; source WAV remains unchanged

• added: independent SmartLink connect/disconnect toggle; disconnecting a remote radio keeps SmartLink connected

• changed: matching LAN/WAN connect-disconnect buttons with visible connection indicators

• changed: uniformly hide slot headers in compact windows and reserve header space in larger windows

• fixed: use a single padding-aware font calculation to prevent short slot titles from wrapping

• fixed: asynchronous transport disconnect and non-blocking UI logging prevent disconnect deadlocks; ignore duplicate connection events

• fixed: require an active GUI station with a TX slice before playback; stop on station loss and guard against stalled audio playback

• fixed: wait for receive confirmation between repeat cycles to avoid interpreting delayed own TX updates as operator PTT
