MyRadioLog: Live Amateur-Radio Transcription and AIOC Push-to-Talk

MyRadioLog is a Windows desktop application for monitoring amateur-radio traffic, creating a searchable transcript log, and operating a simple computer-to-radio audio setup. It brings together live audio capture, Whisper transcription, call-sign handling, audio routing, and AIOC push-to-talk in one local application.

The project is designed to make it easier to follow busy radio traffic, keep a useful history of conversations, and speak through a computer microphone without giving up the familiar feel of a radio station.

What it does

• Captures receive audio from a selected radio-speaker input at 48 kHz mono.
• Uses voice activity detection and faster-whisper to turn received transmissions into live text.
• Tunes transcription for amateur-radio language, phonetic alphabet words, numbers, and call signs.
• Stores logs locally in SQLite, with time, frequency, call signs, transcript text, and decode path.
• Provides date, history, and text-search filters along with editable log entries.
• Saves the most recent 30 seconds of receive audio as a WAV clip.
• Maintains a local call-sign directory and can announce a known operator name through Windows text-to-speech.
• Supports radio receive monitoring through computer speakers.
• Routes a selected computer microphone to the radio-mic output and shows a live PC-mic VU meter.
• Adds an on-screen, press-and-hold PTT control for AIOC PTT1. It automatically releases when the mouse button is released, the application loses focus, the audio route stops, or the application closes.
• Includes persistent light and dark themes, remembered devices, remembered model choice, and remembered frequency.

Screenshots

The main listening view combines audio device selection, radio and PC-mic levels, AIOC push-to-talk, frequency/model controls, decoder status, and the searchable transcript log.

The application also includes a call-sign directory for keeping operator names and usual frequencies alongside the live log.

AIOC hardware

For the computer-to-radio audio and PTT connection, I used the AIOC Ham Radio All-in-One Cable. I bought and soldered the less-expensive DIY version, saved $10, and found the assembly straightforward. MyRadioLog uses the AIOC HID interface to key PTT1 from the on-screen button while the selected PC microphone is routed to the radio-mic output.
