Lab workspace
Work through the six stages. Try the controls. Nothing here receives or transmits a real radio signal.
Stage 2 of 6
SEE IT
Squelch closes the speaker when nothing is stronger than its setting. It does not make a weak signal clearer. A VFO is the frequency you are tuning freely. A memory is a saved frequency you can recall.

FIELD TASK
You are at a trailhead for a later hilltop outing. Your friend says, "We're using 146.520 MHz simplex." Set this handheld so you could listen on that frequency. No relay is involved.
