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.
4.b 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.

### 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 5.3 Know that the purpose of an antenna is to convert electrical signals into radio waves, and vice-versa. 5.4 Recognise a dipole, l/4 ground plane, yagi, end-fed wire and 5/8 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 5/8 antenna are omni-directional. 5.6 Know that a yagi antenna is directional and has a gain because of its focussing ability. 5.7 Know that e.r.p is the product of the power to the antenna and its gain. 5.8 Know that the antenna system must be suitable for the frequency of the transmitted signal. Know that if an antenna is not correctly designed for the frequency it will not match the transmitter and will not work effectively. 5.9 Know that at HF, where an antenna has not been designed for the particular frequency, an ATU (antenna tuning unit) makes it possible for the antenna to accept power from the transmitter.
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 to 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.
### 6. Propagation
6a Radio propagation basics 6.1 Know that radio waves travel in straight lines, unless diffracted or reflected. 6.2 Know that radio waves get weaker as they spread out. 6.3 Know that at VHF and UHF hills cause shadows and that waves get weaker in penetrating buildings but glass windows are more transparent to radio waves. 6.4 Know that the range achieved at VHF/UHF is dependent on antenna height and a clear path and transmitter power. Know that higher antennas are preferable to higher power, as they improve both transmit and receive performance. Know that outdoor antennas will perform better than indoor antennas. 6.5 Know that, at VHF/UHF, range decreases as frequency increases. In general, VHF/UHF waves have a range not much beyond line of sight. 6.6 Know that the ionosphere comprises layers of 'conductive gases' at heights between 70 and 400km 6.7 Know that on HF almost all communication relies on the waves being reflected by the ionosphere. Know that HF can provide world-wide propagation depending on how well the ionosphere bends the waves back to the earth. Know that this varies with frequency, time of day and season.
### 7. EMC |
7a Basics of electromagnetic compatibility 7.1 Know that electromagnetic compatibility (EMC) is the avoidance of interference between various pieces of electronic equipment. 7.2 Know that radio transmitters can cause interference to nearby electronic and radio equipment. 7.3 Know that radio receivers can also suffer from interference from local sources. (This is not considered specifically, but most good EMC practice applies to both conditions.) 7.4 Know that interference occurs through local radio transmissions being conveyed to the affected equipment through pick up in house wiring, TV antenna down-leads, telephone wiring etc., and (particularly at VHF/UHF) by direct pick-up in the internal circuits of the affected equipment itself.
7b Station design for EMC. 7.5 Know that EMC problems can be minimized by siting antennas as far away from houses as possible, as high as possible, and using balanced antennas at HF. Know that, at HF, (horizontal) dipoles are less likely to be a problem and that end-fed wires present significant EMC problems. Know that information on the avoidance of interference by the correct choice and siting of antennas and suitable operating procedures is readily available from several sources. 7.6 Know that the more power a station runs, the more likely it is to cause interference. Know that some types of transmission are more likely to cause interference to TV, radio and telephones than others. Know that SSB is the one of the poorest in this respect. FM, CW (Morse) and the some of the HF data modes (such as PSK31) are much better.
7c Immunity of radio receiving and other devices and filtering techniques. 7.7 Know that the ability of any piece of electronic or radio equipment to function correctly in the presence of strong RF signals is known as "immunity". Know that the immunity of most types of equipment can be increased by fitting suitable external chokes and filters in mains or TV antenna leads. Know that the filters should be fitted as close to the affected device as possible. 7.8 Know that anything fitted to the mains wiring must be properly made for the purpose. Home-made items (other than ferrite rings) are potentially dangerous. Know that information about the purchasing, making and fitting of chokes and filters is readily available from several sources. 7.9 Know that the function of the RF earth connection in an HF amateur station is to provide a path to ground to minimise RF currents entering the mains earth system and causing interference to other electronic equipment.
7d Social issues of Interference. 7.10 Know that EMC problems have the potential for causing neighbour disputes. Understand the need for diplomacy, the sources of advice available and the role of the local office of the Radiocommunications Agency (RIS).

### Morse Code. |
10a Send and receive Morse Code Demonstrate that he/she is able to send correctly by hand and the receiver correctly by ear, texts in morse code signals
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 written assessment.
Note 1 . | The Foundation Licence permits access to both h.f and v.h.f amateur bands.There is no concept of an licence as currently in force for the Novice (Intermediate) and full licence classes.
Note 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.
