HYDRASDR_CALIBRATE(1)

💖 HYDRASDR_CALIBRATE(1) — like, the hydrasdr_rx era 💖

okay bestie, pull up a chair, we're reading a manpage together and honestly? it's giving community service but make it cute. this is the manual page for hydrasdr_rx, and it lives at section 1 of the manual — aka "user commands", aka the stuff you're allowed to just run. no cap. ✨

🦋 NAME 🦋

hydrasdr_rx — receive data using specified parameters. that's it, that's the whole vibe. you tell it what parameters, it brings you data. an icon, honestly. 💅

🌸 DESCRIPTION 🌸

✨ Usage ✨

here's the whole menu of things you can hand it, one by one, no skipping:

• -r <filename> — receives data straight into a file. and here's the little plot twist: if the filename is literally -, the data goes to stdout instead. sneaky but iconic. 🫶
• -w — receives data into a file with a WAV header and an automatic name. this one is for SDR++ compatibility, and heads up — it may not play nice with other software. so like, SDR++ only, bestie, don't get your hopes up elsewhere. 🙈
• -s [serial_number_64bits] — opens the device with the specified 64-bit serial number. picky about which one you mean? this is how you say it. 🎀
• -p [packing] — sets packing for samples:
  • 1 = enabled (12 bits packed)
  • 0 = disabled (default, 16 bits, not packed)
• -f [frequency_MHz] — sets the frequency in MHz, and it has to be between [24, 1850]. default is 900 MHz. stay in your lane, frequency-wise. 🌈
• -a [sample_rate] — sets the sample rate. that's the gig. ⭐
• -t [sample_type] — sets the sample type. choose your fighter:
  • 0 = FLOAT32_IQ
  • 1 = FLOAT32_REAL
  • 2 = INT16_IQ ← the default, the main character
  • 3 = INT16_REAL
  • 4 = U16_REAL
  • 5 = RAW
• -b [biast] — sets the Bias Tee. 1 = enabled, 0 = disabled (default). 💜
• -v [vga_gain] — sets the VGA/IF gain, range 0-15, default 5.
• -m [mixer_gain] — sets the Mixer gain, range 0-15, default 5.
• -l [lna_gain] — sets the LNA gain, range 0-14, default 1.
• -g [linearity_gain] — sets the linearity simplified gain, range 0-21. 🔥
• -h [sensivity_gain] — sets the sensitivity simplified gain, range 0-21. (yes the flag is written exactly like that in the source, we do not editorialize, we simply report 🫡)
• -n [num_samples] — number of samples to transfer. default is unlimited, so like, go off, grab everything. 😭
• -d — verbose mode. for when you want the program to talk to you. 💀
