iDigi is a modern amateur radio digital-mode suite for macOS with FT8, FT4, WSPR, PSK, RTTY, Olivia, MFSK, SSTV, WEFAX, CW, logging and CAT control.
iDigi brings digital amateur radio to your Mac — powerful, native, and easy to use.
With just your transceiver and a sound card, iDigi lets you operate a wide range of digital modes from one consistent macOS application.
Exceptional weak-signal decoding
The FT8 and FT4 decoder has been extensively redesigned with multi-pass decoding, deep decoding, a-priori information and multi-threaded processing. In comparison tests, the new decoder finds around 35% more messages, with most of the additional decodes in the challenging below –18 dB range.
CW decoding has also received a major upgrade. The new decoder delivers around 50% better decoding in our tests, making CW reception significantly more reliable under real-world band conditions.
More digital modes
Operate FT8, FT4, WSPR, PSK31/63/125, QPSK31/63/125, RTTY, CW, SSTV and WEFAX — now joined by Olivia, Contestia and MFSK. SSTV features the most complete set of modes ever in use (> 100 different modes).
Olivia, Contestia and MFSK support numerous tone and bandwidth combinations for robust keyboard-to-keyboard communication. Features such as RSID, AFC, squelch and UTF-8 support make operating and tuning easy. MFSK also supports reception of transmitted images.
Designed for macOS
iDigi is built specifically for macOS, with native Core Audio processing, Apple Keychain integration and a clean interface that feels at home on your Mac. All modes share a consistent operating concept, so switching between FT8, RTTY, Olivia, MFSK, SSTV or CW doesn't mean learning a completely different application.
Integrated logging and online services
Automatic callsign lookup via QRZ.com and HamQTH, customizable macros and an integrated logbook keep everything in one place.
Upload QSOs directly to QRZ.com, eQSL.cc, Club Log, Wavelog or LoTW — without requiring TQSL. iDigi also integrates with N1MM-compatible applications and software such as GridTracker2, RUMLogNG and MacLoggerDX.
Flexible FT8 and FT4 operation
Beyond the improved decoder, FT8 and FT4 provide customizable WSJT-X-style message coloring, received-message filtering, worked-before information, automatic cycle handling and flexible control over contacts and calling frequencies.
Waterfall, images and audio
Use the real-time waterfall to find and tune signals, view propagation on integrated maps, and control supported transceivers through CAT and ATU control.
SSTV provides powerful image handling and customizable overlays, while WEFAX supports automatic image export. Images can also be uploaded automatically by FTP.
Received and transmitted audio can be recorded for later use. iDigi can play recordings back through its decoders at accelerated speeds for most modes — ideal for testing, analysis or decoding slow modes such as WEFAX after the recording has finished.
Whether you enjoy weak-signal DXing with FT8, keyboard QSOs with Olivia or MFSK, CW, image modes such as SSTV and WEFAX, or propagation experiments with WSPR, iDigi brings them together in one modern amateur-radio application for the Mac.
