Construct and test a radio communications device

Assessment tool

Version 1.0
Issue Date: May 2024


This unit describes the skills and knowledge required to plan, build and review a radio communications transmitting or receiving device.

It applies to individuals working as radio maintenance technicians, radio installers and radio repairers who use specialist equipment and work within regulatory and legislative frameworks.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

Elements

Performance Criteria

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare to construct radio communications device

1.1 Prepare for construction, applying all relevant legislation, codes, regulations and standards, and identify any safety issues

1.2 Determine details of radio communications device to be constructed from project specifications

1.3 Produce wiring diagram, component list and block diagram of radio communications device to prepare for construction and testing of device

1.4 Draw up plans showing method of construction and enclosure details

1.5 Designate suitable test points along signal flow paths on circuit diagram for testing of functional blocks

1.6 Produce test setups to evaluate performance of radio communications device

1.7 Obtain tools and test equipment

2. Construct and test radio communications device

2.1 Assemble radio communications device according to circuit diagram and layout drawing

2.2 Test performance and operation of individual functional blocks and overall radio communications device according to test regime

2.3 Transmit or receive signals to evaluate qualitative performance through radio communications device

3. Complete documentation and clean up worksite

3.1 Document results of test procedures and compare with initial project specifications

3.2 Finalise project report and make recommendations for improvement to radio communications device

3.3 Remove waste from worksite according to environmental requirements and restore site to safe condition

Evidence of the ability to:

plan and prepare for construction of a radio communications device

prepare a wiring diagram and component list

construct a radio communications device

test a radio communications device.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

explain electrical symbols and circuit diagrams

summarise the general principles of radio communications and radio propagation

identify and outline the characteristics of:

radio communications components

device pinouts

part numbers

polarities

ratings

summarise the operation and characteristics of:

amplifiers

demodulators

mixers

modulators

oscillators

explain the principles of modulation.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – radio frequency networks field of work and include access to:

sites where radio communications devices may be constructed and tested

test instruments currently used in industry

relevant regulatory and equipment documentation that impacts on work activities.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
