Part 2

Practicals Assessments

10d Practical skills

Select a number and it will take you to the page that describes the practical and the numbers are repeated at the end of each section (as shown below) to allow you to easily move to the next section.

1 2 3 4 5 6 7 8 9 10

Each of the objectives in this section 10d should be read as if they were proceeded with the words "Satisfy the assessors that the candidate is properly able to"

Parts list required to achieve practicals as requested by students


10d.1 read the colour code bands on a number of different resistors and confirm their values measurement.


10d.2 Demonstrate the ability to make good soldered joints.


10d.3 Construct a simple circuit containing a battery, resistor, LED, lamp and switch.


10d.4 Measure potential differences and currents in a simple circuit.


10d.5 Demonstrate that a diode will only conduct in one direction in a simple DC circuit.


10d.6 Demonstrate that a transistor can be used as a switch in a simple DC circuit.


10d.7 Fit a suitable RF connector (PL259, BNC or N-type) to a piece of coaxial cable.


10d.8 Fit a 13A plug to a piece of three-core mains cable.


10e Construction

10e.1 Construct a simple amateur radio related project (e.g. direct conversion receiver, crystal calibrator, ‘grid’ dip meter, ATU and SWR meter, Morse oscillator, audio amplifier) either from a pre-prepared kit or from a published or personal design.

Construction may be carried out either within a course or elsewhere, but the assessor must be satisfied that the bulk of the work is that of the candidate.


10f Simple frequency calibration

10f.1 Calibrate a variable frequency oscillator (VFO) employing an adjustable tuned circuit. Calibration to show the relevant amateur band edges.

The VFO may form part of the project to satisfy 10e.1, or be part of a previously constructed project or provided by the assessor.

The items shown above are assessed as a practical demonstration by the candidate and 'signed off' by the assessor on the Record of Achievement.

Note: If the candidate is disabled in any way that reasonably prevents the carrying out of any practical procedure, he or she may talk another person through the task or describe it to the assessor. The assessor may judge 'disabled'.
