Guidance notes
Note 1
Under the terms of the Wireless Telegraphy Act, 1949 it is an offence to install or use radio apparatus, except under and in accordance with a licence issued by the Secretary of State for Trade and Industry (except for devices exempt from the licensing requirement).
Note 2
A licence is required for the use of a Radar Level Gauge. There is no licence fee to pay, as this is now licence free. A separate schedule is necessary for each location and for different types of equipment. The licence is subject to annual review.
Note 3
The licence is renewable every 12 months and no payment is required. Our Accounts Section will normally send you a reminder a few weeks before the fee is due, when this happens you do not pay a fee, just state you would like to continue with this licence.
Note 4
The submission of an application form for a licence does not permit operation of the equipment. Until the licence has been granted and received by the applicant, installation and use of equipment is an offence under the Wireless Telegraphy Act, 1949.
Note 5
Responsibility for obtaining a licence rests with the licensee not the supplier of the equipment. The application form should be signed by an authorised person employed by the applicant and not the supplier.
Note 6
If the applicant consists of a partnership the full name of each partner should be shown on the application form. If the applicant consists of a non-corporate body, full names and any trading name should be shown on the application form. A licence will normally only be issued to a limited company, a corporate body or a named individual.
Note 7
The equipment must not cause undue interference to any other wireless telegraphy. No protection can be given from interference radiated by other authorised services, or from industrial, scientific and medical (ISM) equipment.
Note 8
If you experience any interference to your system you should contact your supplier in the first instance.
Note 9
Any proposed change in the details, of the system (equipment, details, location, etc.) must be notified immediately to the address given in note 12.
Note 10
If you are an existing holder of a valid Radar Level Gauge Radio Licence and are using this form to request an additional schedule to your licence, you should not send a fee with this application. In such cases you should return this form to our London address, given at the end of these notes, and not to our Accounts Branch. It is very important to quote our customer reference given on the current licence.

Note 11
Guidance to class of emissions
Introduction
Emissions are designated according to their necessary bandwidth and modulation and are coded internationally using seven characters for their basic parameters and two optional characters for further details of the signal. Modulation used only for short periods and for incidental purposes (such as for identification or calling) may be ignored.
Necessary bandwidth
The necessary bandwidth is expressed by three numerals and one letter. The letter occupies the position of the decimal point and represents the unit of bandwidth, e.g. Hz, kHz, and MHz.
For example, the necessary bandwidth codes use the following letters:
From 0.001 to 999 Hz = H From 1.00 to 999 kHz = K From 1.00 to 999 MHz = M From 1.00 to 999 GHz = G
Note: The first character shall be neither zero nor K, M or G.
Examples:
Note: Carrier only is expressed as 1H00
Class of emission The basic characteristics are
First character Please use the following characters to identify type of modulation. N Emission of unmodulated carrier.
Types of emissions in which the main carrier is amplitude modulated (including cases where sub carriers are angle modulated): A Double sideband H Single sideband, full carrier R Single sideband, reduced or variable level carrier J Single sideband, suppressed carrier B Independent sidebands C Vestigial sideband.
Types of emission in which the main carrier is angle modulated: F Frequency modulation G Phase modulation D Emission in which the main carrier is amplitude and angle modulated either simultaneously or in a pre-established sequence.
Emission of pulses Emissions where the main carrier is directly modulated by a signal which has been coded into quantized form (e.g. pulse code modulation) should be designated under the sections above. P Sequence of unmodulated pulses. A sequence of pulses: K modulated in amplitude L modulated in width/duration M modulated in position/phase Q in which the carrier is angle modulated during the period of the pulse V which is a combination of the foregoing or is produced by other means W Cases not covered above, in which an emission consists of the main carrier modulated, either simultaneously or in a pre-established sequence, in a combination of two or more of the following modes: amplitude, angle, pulse. X Cases not otherwise covered.
Second character O No modulating signal 1 A single channel containing quantized or digital information without the use of a modulating sub-carrier. This excludes time-division multiplex 2 A single channel containing quantized or digital information with the use of a modulating sub-carrier. This excludes time division multiplex 3 A single channel containing analogue information 7 Two or more channels containing quantized or digital information 8 Two or more channels containing analogue information 9 Composite system with one or more channels containing analogue quantized or digital information, together with one or more channels containing analogue information X Cases not otherwise covered
Third character
Note: The term "Information" does not represent a signal of a constant unvarying nature, as provided by standard frequency emissions, continuous wave and pulse radars, etc.
N No information transmitted A Telegraphy for aural reception B Telegraphy for automatic reception C Facsimile D Data transmission, telemetry, telecommand E Telephony (including sound broadcasting) F Television (video) W Combination of the above X Cases not otherwise covered
Description of emission (optional) These are:
Where the fourth or fifth characters are not used please indicate on the form by a (-) where each character would otherwise appear.
Fourth character A Two-condition code with elements of differing numbers and/or durations B Two-condition code with elements of the same number and duration without error-correction C Two-condition code with elements of the same number and duration with error correction D Four-condition code in which each condition represents a signal element (of one or more bits) E Multi-condition code in which each condition represents a signal element (of one or more bits) F Multi-condition code in which each condition or combination of conditions represents a character G Sound of broadcasting quality (monophonic) H Sound of broadcasting quality (stereophonic or quadraphonic) J Sound of commercial quality (excluding categories given in K and L below) K Sound of commercial quality with the use of frequency inversion or band-splitting L Sound of commercial quality with separate frequency-modulated signals to control the level of demodulated signal M Monochrome television (video only) N Colour television (video only) W Combination of the above X Cases not otherwise covered
Fifth character N No multiplexing employed C Code division multiplex. (This includes bandwidth expansion techniques) F Frequency-division multiplex T Time-division multiplex W Combination of frequency-division multiplex and time-division multiplex X Other types of multiplexing
Definitions in this note are based on the Radio Regulations published by the International Telecommunications Union, 1998.
