Technician Core · Labs · TC-07

Measure, Test & Troubleshoot

Meters, a dummy load, and faults you isolate one measurement at a time.

NOT STARTED

Lab workspace

Work through the six stages. This is Technician Core, built on Foundations. Finishing the lab does not mean the idea is mastered, and it is not Technician exam readiness.

  1. LEARN
  2. SEE IT
  3. DO IT
  4. EXPLAIN IT
  5. EXAM CONNECTION
  6. FIELD TASK

Stage 1 of 6

LEARN

When a station fails, the job is to find out why. Observe, check the simple things, measure, isolate one part, then confirm. A multimeter does not do voltage, current, and resistance with the same connections. This bench will refuse an unsafe setup instead of inventing a reading.

Stage 2 of 6

SEE IT

An SWR meter and an RF power meter answer different questions. A dummy load lets you test the transmitter without using the antenna as the load. The readings below are the lab's cases, not a calibration certificate.

Stage 3 of 6

DO IT

Four stations are broken. You get the symptom only. Measure before you decide. Change one thing, the thing the evidence points at.

Stage 4 of 6

EXPLAIN IT

Why is changing several things at once a poor troubleshooting strategy?

Stage 5 of 6

EXAM CONNECTION

RADIO LAB PRACTICE. These questions are about the measurements you just chose. They are not official exam questions.

Stage 6 of 6

FIELD TASK

Halfway through a portable outing the station goes dark. Diagnose it on the bench and restore the one failed part. Do not swap everything in the pack.
