FM radio in SDRCrew: free tuning, one dongle, no frills

Among SDRCrew's tabs there is also an "old-style" receiver: no waterfall, no spectrum to read - just the frequency, the mode, and the audio starts. Designed for when you simply want to listen, not analyse.

What it does

Free tuning across the whole band your dongle covers, with FM broadcast (87.5-108 MHz) as the main use case - the classic home FM radio, but via SDR.

Multi-mode: besides FM also AM, CW, USB, LSB. With a single dongle you can go from listening to a broadcast station to monitoring a CW or SSB frequency.

A real-time S-meter to get an idea of how strong the signal you are receiving is.

A dedicated reception process (rtl_fm), light and direct: designed to stay on in the background without weighing on the machine.

Work in progress: RDS decoding (station name, RadioText) is under development - the pilot tone lock works very well, but the part that extracts the text is not reliable yet. I am working on it, it will come.

As always, free and open. Try it, listen, and if you find something wrong (or have an idea) write to me from the contacts in the Info tab. A coffee to support development is always welcome ☕.

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 ...
