A Windows 11 ApplicationCall-Catcher & Lightning Logger
- Catch the callsign
- Enrich the conversation
- Remember the friendship
Turn a callsign into a conversation—and a conversation into a friendship. Let the computer handle the capture, lookup, and recordkeeping while you focus on the person behind the callsign.
Two applications · one operating flow
Hear it. Catch it. Know it. Remember it.
Call-Catcher listens to selected computer audio, identifies likely callsigns, and passes accepted detections to Lightning Logger. Review captured callsigns at your convenience without worrying that one will be lost while the QSO moves on.
Know who is calling
Accepted callsigns open fast access to operator information instead of repeated manual QRZ searches.
Find a conversation
Available photos, location, local time, and weather provide natural ways to move beyond a signal report.
Remember the QSO
A searchable local contact history and personal notes help you recognize returning operators and resume earlier conversations.
The real purpose
Spend less time at the keyboard and more time enjoying amateur radio.
Whether you are joining a net or enjoying a relaxed chat, the details stay handy while you focus on the operator—not the software.
Project demonstration
See Lightning Logger and Call-Catcher work together.
The demonstration shows callsign capture, operator lookup, and the choice to log—or not log—the QSO.
