SDRCrew 2.0 is out

SDRCrew 2.0

It's here: SDRCrew 2.0 is available. It's the biggest overhaul since the program was born: a new interface, new tabs, a separate window for the digital modes, and three decoders (SSTV, RDS and DAB) that I rebuilt or improved by measuring them against real signals.

NEW INTERFACE

  • Side menu with search and categories (Reception, Aviation & maritime, Data & digital, Music & broadcasting), each collapsible with an arrow.
  • Large orange frequency readout and S-meter at the top of every receiving tab.
  • The cards on the right (Source, Memories, IQ recording...) start closed and the app remembers how you leave them.
  • Dark, light or "follow Windows" theme, switched instantly.
  • If a receiver is busy, the app asks whether to stop the other reception instead of throwing an error.
  • The Info tab has a form to send me bug reports and requests, anonymously if you like.

WHAT'S NEW

  • Citizen Band: 40 CEPT channels, bands A-F, alpha channels, 1/5/10 kHz steps, AM/FM/SSB, S-meter and scanning.
  • DMR / D-STAR / C4FM: repeater list by country, Memories and a heard-stations history that survives closing the app.
  • Shared Memories on SDR, KiwiSDR and the other tabs.
  • ACARS and VDL2: an Aircraft card with registration, operator, model and photo.
  • TETRA: SDS messages (TETRA's "SMS").
  • DAB: favourite stations with a star, search by name, multiplex or channel.

DIGITAL MODES IN A SEPARATE WINDOW

FT8, FT4, FT2, WSPR, JS8 and SSTV open in their own window, from the SDR tab and from the KiwiSDR tab. Every decoded message is written to a monthly CSV file by itself and the statistics are rebuilt from the log, so they are never lost. There is also a GridTracker-style map of the stations heard, and a country flag in front of every country name.

SSTV

Much more sensitive, it starts even without a VIS header, and a burst of interference or a fade of up to 30 seconds no longer splits the picture. Received pictures are cleaned up automatically (noise, ruined lines, colour, sharpness) and the untouched original is kept in a separate folder.

RDS

Rebuilt decoder: it locks the 57 kHz subcarrier by itself, so mono stations work too. On a real station it decodes 97% of the blocks against 12% before, with the full name and RadioText.

DAB

"Auto" gain is now a software gain control on the signal level, because the tuner's own AGC does not work with DAB. The scan finds weak multiplexes it used to miss, including the Rai multiplex next to a very strong neighbour: on my dongle 10 multiplexes instead of 5-7, in about 4.5-5 minutes.

SDRCrew 2.0 sta arrivando

Immagine
Sto chiudendo gli ultimi dettagli di SDRCrew 2.0, la più grossa revisione da quando è nato il programma. Non c'è ancora una data precisa: esce quando l'ho provato abbastanza da fidarmi. Intanto, ecco cosa troverete. NUOVA INTERFACCIA - Menu laterale con ricerca e categorie (Ricezione, Aviazione e mare, Dati e digitale, Musica e broadcasting) che si compattano con una freccetta. - Frequenza grande in arancione e S-meter in testa a tutte le schede di ricezione. - Tutte le card a destra (Sorgente, Memorie, Registrazion e IQ...) si possono chiudere, e il programma ricorda come le avete lasciate. - Tema scuro, chiaro oppure "come Windows", cambiato al volo dalle impostazioni. - Mappe più grandi su ADS-B e AIS. NOVITÀ - Citizen Band: 40 canali CEPT, AM/FM/SSB, bande A-F, S-meter e scansione dei canali. - DMR / D-STAR / C4FM: scheda Sorgente come quella dell'SDR, elenco ripetitori filtrato per Paese, Memorie e storico degli ascolti che resta anche dopo la chiusura. - Mem...

SDRCrew 1.0.3 — more solid FT2 decoding

An update on the app's "engine" side: two external decoders have been updated to the latest versions. 📡 Digital decoding (FT8/FT4/FT2) Until now FT2 decoding relied on an internal trick (it reused the FT4 command with different timing). From this version the engine I use has changed: now FT2 has a dedicated, native command, which makes it more stable and reliable. FT8 and FT4 remain unchanged - I have already tested them live and they keep working as before. 📻 Digital voice (DMR/D-STAR/Fusion) The digital voice decoder has been updated as well: native support for Airspy R2/Mini dongles, faster recovery of DMR control channels when the signal drops, and various refinements. Update available through the app or on Codeberg.

Shortwave in SDRCrew: HF tuning + know what you will hear

Immagine
Shortwave (2.3-26.1 MHz) is probably the most fascinating part of the radio spectrum - and the hardest to explore "at random": signals that bounce off the ionosphere and arrive from thousands of kilometres away, but with times and frequencies that change season by season. Turning the knob hoping to find something worked in the 1980s. Today we can do better. What the tab does Full HF reception (2.3-26.1 MHz), with direct sampling enabled by default: below about 24-28 MHz many RTL-SDR dongles receive nothing without it, since shortwave is below the classic tuner's limit. A real schedule, not a static list: almost 8,000 broadcast transmissions catalogued (source EiBi, updated each broadcast season), with station, language, target area and time. Search by station name or language, and an "on air now" filter that compares the current UTC time with the schedule - no more wasted attempts on a station that perhaps only broadcasts at night. Double-click a result and the ...
