4. Transmitters and Receivers
|
|
4a
Simple block or "concept" diagrams of a transmitters. |
4.1 State the items in a simple transmitter block diagram: Microphone, audio amplifier stage, frequency generation stage, modulator stage, RF power amplifier stage, feeder and antenna. Identify their interconnection. |
4b Technical requirements of radio transmitters |
4.2 Know that the frequency generation stage(s) (e.g. oscillator(s)) in a transmitter defines the frequency on which the transmitter operates. Know that incorrect setting of these stages can result in operation outside the amateur band and interference to other users. |
4.3 Know that the audio (or data) signal is modulated on to the radio frequency carrier in the modulation stage of the transmitter block diagram. Know that modulation is by varying the amplitude or frequency of the carrier, resulting in AM or FM modulation modes. Know that speech can be carried by AM/SSB or FM, and data by CW or FSK. |

|
5. Feeder and Antenna |
|
5a Feeder requirements |
5.1 Know the correct cable to use for rf signals. Because of its screening qualities, Coaxial cable is most widely used |
5.2 Know that the plugs and sockets for RF should be of the correct type and that the braid of coaxial cable must be correctly connected to minimise RF signals getting into or out of the cable. The BNC and PL259 plugs should be recognised. |
|
5b Types of antenna | |
5.4 Recognise a dipole, λ/4 ground plane, yagi, end-fed wire and 5/8λ antenna. Understand that the sizes of HF and VHF antennas are different because they are related to wavelength, though they operate on the same basic principles. |
|
5c Antenna basics |
5.5 Know that dipoles (mounted vertically), ground planes and 5/8λ antenna are omni-directional. |
5.6 Know that a yagi antenna is directional and has a gain because of its focussing ability. |
|

|
5d Balanced antennas |
5.10 Know the difference between balanced and unbalanced antennas and that a balun should be used when feeding a H.F. dipole with coaxial cable. |
5e Meaning of SWR |
5.11 Know that an SWR meter shows whether an antenna presents the correct match to the transmitter and is reflecting minimum power back to the transmitter. |
5.12 Know that a high SWR (measured at the transmitter) is an indication of a fault in the antenna or feeder (and not the transmitter). (Relate this to item 4.6.) |
|
5f Use of a dummy load |
5.13 Know that a "dummy load" is a screened resistor connected instead of an antenna to allow the transmitter to be operated without radiating a signal |

10. Morse Code |
|
The ITU Radio Regulations places an obligation on national Administrations to require candidates to demonstrate that he/she is able to send correctly by hand and to receive correctly by ear, texts in Morse code signals. The requirement is waived for access to frequencies above 30MHz. It is expected that this requirement will be removed at the next world radio conference, WRC2003. It is then open to administrations to consult their amateurs as to whether the requirement should be retained as a national arrangement. Until the requirement is removed, the following section forms a part of the syllabus. This section may be taken at any time in relation to the training course but prior to the exam. - See Note 1. |
|
10a Send and Receive Morse Code |
10.1 Demonstrate that he/she is able to send correctly by hand and to receive correctly by ear, texts in Morse code signals. |
Notes:
1. The Foundation Licence permits access to both h.f and v.h.f amateur bands.
There is no concept of an "A" or "B" licence as currently in
force for the
Novice (Intermediate) and full licence classes.
2. Tutors are advised to read "Foundation Training Course - A Guide to
Tutors" produced by the Radiocommunications Agency. The Guide also has a
glossary explaining some of the terms used and sources of further reading.
