LEARN
A radio is already surrounded by many signals. They are all there at the same time. Turning the tuning control does not make a station start transmitting. It chooses which frequency this receiver listens to.

What Is Radio?
Explore frequency, wavelength, signals, noise, Hz/kHz/MHz, and basic receiver behavior.
NOT STARTED
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
Tune the simulated receiver. The signals stay in place. You are choosing which frequency it listens to. This is a simulation, not a live reception.
Stage 3 of 6
DO IT
Tune the receiver to finish each challenge. Resetting the dial does not erase your lab progress.
Stage 4 of 6
EXPLAIN IT
When you turn the tuning control on a radio, what are you actually changing?

EXAM CONNECTION
RADIO LAB PRACTICE. These questions are about the receiver you just used. They are not official FCC exam questions.

FIELD TASK
You are getting ready for a hilltop outing with a friend. This is not a full Summits on the Air lesson. It is the same tuning idea, with a reason to use it. Your friend says the group will talk on 146.520 MHz, everyone on that same frequency. The radio in front of you currently shows 162.550 MHz.
