pichirp: a carrier sweep

Sweeps a carrier across a band around a center frequency, over a given time. Code: pichirp.go.

Fields

JSON	Go field	Type	Required	Rules
frequency	Frequency	float64	yes	Center frequency in Hz, 5000 to 1500000000
bandwidth	Bandwidth	float64	yes	Sweep width in Hz, greater than 0
time	Time	float64	yes	Sweep duration in seconds, greater than 0

Example

{
  "frequency": 434000000,
  "bandwidth": 100000,
  "time": 5
}

Runs:

stdbuf -oL "$GORPITX_PATH/pichirp" 434000000 100000 5

The arguments are positional: frequency, bandwidth, time. Frequency and bandwidth are rounded to whole Hz; time keeps its decimals.
