SDRCrew 1.4.3: KiwiSDR remote receivers and 26 SSTV modes

SDRCrew 1.4.3 is out, with two new things: you can listen to HF from receivers all over the world without a dongle or an antenna, and SSTV now recognises 26 modes.


NEW TAB: KIWISDR / WEB-888

- Connect to a KiwiSDR or a Web-888 (yours too) and get audio, the 0-30 MHz waterfall and an S-meter

- Pick from about 860 receivers on the public kiwisdr.com list, searchable by place, name or antenna with a free-slots filter; or type an address

- Tune with the band buttons, the frequency, the steps or a click on the waterfall; USB, LSB, CW, AM and FM modes

- FT8 and FT4 decoding of the remote audio, with country and SNR for every station: I tested it live and it works

- The Hi-Fi tab records what you hear from the remote receiver

Verified on real public receivers. I have not tried it yet with a real Web-888 or with password-protected receivers: if you use one, let me know how it goes.


SSTV: FROM 13 TO 26 MODES

- Martin M3 and M4, Wraase SC2-120 and SC2-180, Pasokon P3, P5 and P7

- Robot 8, 12 and 24 in black and white; Robot 24 and Robot 72 in colour; FAX480

- Tested with synthetic signals, not yet with real transmissions: reports are 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 ...
