HYDRASDR_ASYNC_RX(7)

📦 version 1.1.1, in ubuntu stonking

💖 HYDRASDR_ASYNC_RX(7) 💖

okay bestie, pull up a chair 🫶 this is HYDRASDR_ASYNC_RX(7), the manual for hydrasdr_async_rx — no cap, your whole personality this afternoon is capturing IQ data and that's iconic of you.

🌸 NAME 🌸

hydrasdr_async_rx — HydraSDR Async RX Tool. periodt 💅

✨ DESCRIPTION ✨

She receives data. Into a file. That's the vibe, that's the whole main character arc 💾✨

🎀 USAGE 🎀

hydrasdr_async_rx -o <file> [options]

👑 OPTIONS 👑

🚨 Required (do NOT skip her, fr fr)

  • -o <file> — the output file where your captured data lands. No -o, no data, we don't make the rules 😭

🦋 Optional (the fun little extras)

  • -f <MHz> — set RF frequency in MHz (like 100.5 — yes queen, decimals are allowed 💜)
  • -s <SPS> — set sample rate
  • -B <Hz> — set bandwidth (only if your device supports it, iykyk)
  • -t <type> — set sample type:
    • 0 = FloatIQ
    • 1 = FloatReal
    • 2 = Int16IQ
    • 3 = Int16Real
    • 5 = Raw
  • -p <0/1> — packing mode: 0=16-bit, 1=12-bit packed (if supported)
  • -P <port> — select RF port (0-based index, so the first one is 0, not 1, we're programmers here)
  • -D <0/1> — decimation mode: 0=Low Bandwidth (default), 1=High Definition
    • High Definition uses highest HW sample rate with decimation 🔥
  • -h — show help

🎚️ Gain control (device-specific, in priority order)

these are all "if supported by your device" coded, so don't come for me if yours is picky 🙈

  • -g <value> — set linearity gain (if supported)
  • -G <value> — set sensitivity gain (if supported)
  • -l <value> — set LNA gain (if supported)
  • -r <value> — set RF gain (if supported)
  • -m <value> — set Mixer gain (if supported)
  • -F <value> — set Filter gain (if supported)
  • -v <value> — set VGA gain (if supported)
  • -a <0/1> — LNA AGC off/on (if supported)
  • -A <0/1> — Mixer AGC off/on (if supported)
  • -b <0/1> — Bias-T off/on (default: 0)
💡 Note: connect a device and run with -h for device-specific defaults and ranges. literally the cheat code, use it 💅
