What are the system requirements?
macOS 14 Sonoma or later. Include your Mac model in your beta request so we can confirm the right build. You can analyze recordings without a receiver; live capture needs compatible radio hardware and its runtime library.
Which SDRs work?
RTL-SDR, HackRF One, USRP (via UHD), SignalHound BB60, HydraSDR RFOne, and devices with a compatible SoapySDR module. Device support depends on your module and library versions. Common libraries install with one Homebrew command and Sigil picks them up at runtime; see receiver setup and compatibility for details.
Do I need an SDR at all?
No. Sigil opens IQ recordings directly (SigMF, raw float/int formats, WAV, BLUE, SDVR), and the whole analysis workflow works on files. A radio is only needed to capture live signal.
I lost my license key. Can you resend it?
Yes. Email support@sigil.radio from the address the key was issued to and we'll resend it. Self-serve recovery is coming.
How do updates work?
The app updates itself: signed, notarized builds delivered through the built-in update mechanism (Sparkle). You can check manually or turn automatic checking off in Preferences. Update checks send no usage data; see the privacy policy.
Where are my session logs?
Help ▸ Reveal Session Log in Finder, or ~/Library/Logs/Sigil. The most recent 25 sessions are kept, on your Mac only; they're never sent anywhere unless you attach them to a report.
How do I join the beta?
Request beta access. The request opens your email app; you can also write to support@sigil.radio. Selected testers receive named, expiring evaluation keys under the beta agreement. The beta pathway will continue after launch. The planned public offer is a full 30-day trial, then a $39.99 USD one-time purchase; see availability.
Refunds?
The proposed refund policy provides a 14-day window once purchasing opens, pending final policy review.
