Stage 1 of 7
LEARN
TC-05 introduced modes. This bench is the widths, the sideband convention, and the activities those modes are used for. A mode is how the information rides on the radio wave, and how much spectrum that ride occupies.

Modes, Satellites & Digital Activities
Mode bandwidth, upper and lower sideband, digital activities, fast-scan television, and a low-Earth-orbit pass.
NOT STARTED
Lab workspace
Work through the six stages. This remediation lab fills a gap left by Foundations and Core. Finishing it does not finish the Technician syllabus, and it is not Technician exam readiness.
Stage 2 of 7
SEE IT
Digital activities exchange structured information. A television picture is still a radio emission with a very wide footprint. A low-Earth-orbit satellite is only available while it is in view.
Stage 3 of 7
DO IT
Pick the activity that fits the goal. None of these is required to hold a license. FM is the usual voice mode on VHF and UHF repeaters, and it is also common for VHF packet. SSB is the weak-signal voice choice and uses less spectrum than FM. SSB is a form of amplitude modulation. CW is on-off keying and is the narrowest of the modes on the bench.
Stage 4 of 7
EXPLAIN IT
Why isn't choosing a radio mode only a matter of deciding whether you want voice or data?
Stage 5 of 7
EXAM CONNECTION
Radio Lab practice from this bench. Not the official pool.
Stage 6 of 7
FIELD TASK
You are on a hill with a dual-band handheld, a notebook of satellite passes, and an hour. One goal is a local voice contact. Another is a weak digital contact. A LEO satellite is due in twenty minutes.
Stage 7 of 7
ONE MORE CHECK
The pass you already ran did not include rotation, the published mode, or how to set uplink power.
