Use when a receiver runs but produces no output, noise, or the wrong result — systematically locate the fault instead of guessing, using render and measure to see the problem.

Use when the user wants to receive or demodulate a specific signal — build, validate, run, and verify a receiver pipeline, then save it as a reusable, GRC-openable flowgraph.
Use ONLY as a last resort when no Marconi tool or vocabulary block can express the task — write a Python script against the marconi library, run it, and report the capability gap.
Use when the user wants a test signal or a simulated RF environment with no hardware — translate intent into a scene and register it as a persistent simulated device.
Use when the user wants to know what signals are present — characterize a capture or a simulated device's spectrum (PSD, signal detection, spectrogram) and summarize what's on the air.
Use when the user wants a closed-loop transmit-then-receive experiment in simulation — transmit a capture into a simulated device's scene and receive it back to confirm the link.

A receiver that runs status: ok but produces silence or garbage has a DSP fault, not a crash. Find it systematically; do not randomly tweak parameters.
spectrogram (and/or psd_plot) of the channelized capture — the stage right after freq_xlating_lowpass — and measure it. Most faults are visible there.center_offset value or its sign is wrong (center_offset = target_freq − capture_center_freq).quad_rate. Check sample_rate / decimation.cutoff below the signal bandwidth clips it (muffled/silent); far too wide lets in neighbors (noisy).measure the channelized capture: very low SNR means you channelized empty spectrum — re-check the target frequency from survey-spectrum.nbfm_rx, quad_rate must be an integer multiple of audio_rate; a wav_sink sample_rate must match the audio stream rate.
