FAQ — Radio Bench

Trial and licence

Is it a subscription?: No. Buy once for two computers. All future Radio Bench updates included. No subscription. No annual maintenance or support fee.
Can I try before buying?: Yes. Download the app for a 30-day trial with all features and no signup. When the trial ends, you need a paid licence to continue.
How many computers can I use it on?: Two. Deactivate a computer in Settings → License to free its place. The licensing guide explains replacing a computer you can no longer access.
Does it work offline?: After online activation, a paid licence works offline indefinitely. Trials still end on their expiry date.
Can I get a refund?: Yes. Request a full refund within 14 days of purchase. See the refund policy.

What hardware does it support?: Airspy HF+ and RTL-SDR receivers, RTL-TCP, SpyServer and KiwiSDR network connections, and IQ WAV recordings. KiwiSDR lets you listen through a remote station without a local SDR. A Hamlib-supported transceiver is optional for rig control. Check the hardware guide for exact models and requirements.

What is Radio Bench?: A native desktop app for HF amateur radio. It brings the SDR spectrum and waterfall, CAT transceiver control and a local QSO logbook into one workspace on macOS, Windows and Linux.
Why use Radio Bench if I already have SDR software?: Radio Bench brings listening, transceiver control and contact logging together. You can tune the band, follow a Hamlib-supported rig and keep an ADIF-compatible log in the same app. It is a good fit if you want those everyday HF tools together on macOS, Windows or Linux. Check the supported receivers and try it with your station before buying.
Does the app collect telemetry?: No usage analytics or automatic crash reports. The app connects for activation, updates and services you use. See the privacy notice for details.
Who builds it?: VK3DTX. Radio Bench is a one-person project. Read more about Radio Bench.

How do I get help?: Use the contact form. For a bug report, include your app version, operating system, radio and steps to reproduce it. The support report guide explains how to include diagnostics.
What happens if reception stops?: Radio Bench reports a stalled stream and can recover from some USB interruptions. See the troubleshooting guide if it continues.
