<\/a>OrcSDR i praktiken<\/p>\n

SDR-donglar som den popul\u00e4ra RTL-SDR Blog V4 erbjuder robust och m\u00e5ngsidig lyssningsfunktion till ett \u00f6verkomligt pris. Deras b\u00e4rbarhet kr\u00e4ver dock ofta en skrymmande b\u00e4rbar dator f\u00f6r str\u00f6mf\u00f6rs\u00f6rjning, signalbearbetning och visning av resultat. Det \u00f6ppna k\u00e4llkodsprojektet OrcSDR l\u00f6ser detta genom att f\u00f6rvandla en vanlig utvecklingssurfplatta till en dedikerad, b\u00e4rbar radio.<\/p>\n

OrcSDR-projektet<\/a> kretsar kring M5Stack Tab5, en batteridriven handh\u00e5llen surfplatta som drivs av en dual-core RISC-V ESP32-P4-processor. Genom att ansluta en RTL-SDR direkt till Tab5:s USB-v\u00e4rdport sk\u00f6ter ESP32 det tunga arbetet: den bearbetar den r\u00e5a digitala radiostr\u00f6mmen, demodulerar ljudet och \u00e5terger ett live, pekk\u00e4nsligt spektrum och en vattenfallsdisplay p\u00e5 en 5-tums f\u00e4rgsk\u00e4rm utan en PC. <\/p>\n

F\u00f6r f\u00e4ltanv\u00e4ndning \u00f6verbryggar OrcSDR den stora prisskillnaden mellan billiga datordonglar och dedikerade kommersiella digitala skannrar f\u00f6r 650 dollar, som Uniden SDS100. F\u00e4lttekniker, frivilliga inom s\u00f6k- och r\u00e4ddningstj\u00e4nsten samt radioamat\u00f6rer f\u00e5r en allt-i-ett-skanner f\u00f6r snabba platsunders\u00f6kningar och mycket mer. Den b\u00e4rbara enheten kan till exempel sp\u00e5ra transpondrar p\u00e5 flygplan i luften via realtids-ADS-B-avkodare, verifiera t\u00e4ckningen f\u00f6r Meshtastic- och LoRa-paket utanf\u00f6r n\u00e4tet, kontrollera lokal \u00f6verbelastning p\u00e5 2,4 GHz Wi-Fi samt lyssna p\u00e5 okrypterade digitala P25-n\u00f6dradios\u00e4ndningar. <\/p>\n

Eftersom projektet distribueras som en f\u00f6rkompilerad flashbild via det webbl\u00e4sarbaserade verktyget M5Burner kan anv\u00e4ndare drifts\u00e4tta programvaran p\u00e5 n\u00e5gra minuter utan att beh\u00f6va kompilera k\u00e4llkod. Genom att kombinera en billig USB-tuner med moderna SoC:er bevisar OrcSDR att praktiska RF-analysverktyg i fickformat inte l\u00e4ngre kr\u00e4ver dyr kommersiell h\u00e5rdvara eller en b\u00e4rbar dator f\u00f6r att komma ig\u00e5ng. F\u00f6r den som \u00e4r intresserad av att bygga sin egen OrcSDR finns projektinformation tillg\u00e4nglig via l\u00e4nken nedan. <\/p>\n
