Activating your license

After you buy RimuSDR, you receive a license code by email. Activate the installation before you use it.

What you need

License code

The unique code sent to your email after purchase.

Callsign

Your amateur radio callsign, as registered at purchase.

Internet connection

Required for activation only, not to run RimuSDR afterward.

Activate RimuSDR

1. Open RimuSDR from your application menu, or run rimusdr in a terminal.

2. Go to Help › Activate License.

3. Enter your license code and your callsign.

4. Click Activate.

A confirmation message appears when activation is complete.

1. Restart RimuSDR.

How the license works

Each license is tied to one user and one callsign. It is perpetual, with no subscription, and includes all version 1.x updates.

Up to 10 installations

You can activate RimuSDR on up to 10 computers at the same time.

Tied to the hardware

The license code is tied to the computer's hardware. Deactivate before you move it to another computer.

Activated once per computer

The license is verified with the activation server, then stored locally. RimuSDR does not need an internet connection to run afterward.

Troubleshooting

Connection errors

If activation reports a connection error:

1. Confirm the computer has a working internet connection.
2. Confirm your firewall permits RimuSDR.
3. Wait a few moments, then activate again.

The license code is not accepted

1. Compare the code against your purchase confirmation email.
2. Copy the code directly from the email. This prevents typing errors.
3. Check the capitalization. License codes are case-sensitive.

Callsign errors

1. Enter your callsign exactly as registered.
2. Remove slashes and other modifiers.
3. Use the same callsign you gave at purchase.

Transferring your license

Deactivate before you move or uninstall

Go to Help › Deactivate License before you uninstall RimuSDR or move to another computer. This frees the activation for use elsewhere.

Reaching the 10-computer limit

Deactivate RimuSDR on one computer before you activate it on a new one.

Reinstalling the operating system

A computer reinstalled without deactivating still counts against your 10 activations. Contact support for help.

Lost license code

Contact support with your callsign and purchase information.

Next steps

1. Connect your FlexRadio to the same network as your computer.
2. Start RimuSDR. It discovers the radio automatically. See Connecting to your radio.

If activation still fails, contact support with your callsign, your license code, and the exact error message.
