Part of our Building Your First Ham Radio Station guide.
Modern shacks lean on software for logging, digital modes, CAT control, and often remote operation, which means a dead computer can take your entire station offline just as effectively as a dead radio, and most hams have a backup plan for the radio but not the computer.
Why This Is a Real Gap
A radio failure is usually obvious and often has a clear workaround, a different radio, a manual mode. A computer failure can quietly take out your logging, your digital modes, your CAT control, and your remote access all at once, especially in a station where WSJT-X, Ham Radio Deluxe, and your logger all depend on that one machine running correctly.
You Do Not Need a Duplicate Machine
A full backup computer with every program pre-installed and configured is nice but not strictly necessary. What actually matters is having your software licenses, configuration files, and a documented setup process saved somewhere accessible, so that any spare computer, a laptop you already own, an old machine in a closet, can be pressed into service reasonably quickly if your primary shack computer dies.
What to Actually Keep Backed Up
- Your logging software database or a recent ADIF export, covered separately in your logbook backup routine.
- Configuration files for WSJT-X, your logger, and any CAT control software, so you are not reconstructing settings from memory.
- A written note of your CAT control com port settings, baud rates, and any radio-specific quirks you have already worked out through trial and error.
- Installer files or download links for the specific software versions you actually use, since re-downloading everything during an actual outage wastes time you may not have.
Testing the Plan Before You Need It
For the logbook side of this, see Building a Backup and Sync Routine for Your Logbook.
Actually try setting up your backup machine from your saved configuration and installers once, even as a one-time exercise, rather than assuming your plan will work when you are stressed and your primary computer just died mid-contest or mid-emergency. Finding gaps in your backup plan during a calm test run is far better than finding them when you actually need it.
