Introduction
This ETS was drafted on the assumption that:
- the type test measurements performed in an accredited test laboratory in one country would be
accepted by the Type Approval Authority in another country provided that the national regulatory
requirements are met;
- if equipment available on the market is required to be checked it should be tested in accordance
with the methods of measurement specified in this ETS.

1 Scope
This ETS is intended to specify the minimum performance and the methods of measurement of radio
equipment for use in the land mobile service as specified in the Scope. Clause 5 provides the
corresponding limits. These limits have been chosen to ensure an acceptable grade of service and to
minimise harmful interference to other equipment and services. They are based on the interpretation of the
measurement results described in subclause 4.3.
This ETS covers the minimum characteristics considered necessary in order to make the best use of the
available frequencies. It does not necessarily include all the characteristics which may be required by a
user, nor does it necessarily represent the optimum performance achievable. It applies to equipment with
integral antennas, used in angle modulation systems in the land mobile service, operating on radio
frequencies between 30 MHz and 1 000 MHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz,
and is intended primarily for analogue speech.
This ETS is based upon CEPT Recommendation T/R 24-01 annex III [1], and is a general standard which
may be superseded by specific standards covering specific applications.
In this ETS different requirements are given for the different radio frequency bands, channel separations,
environmental conditions and types of equipment, where appropriate.
The measurement methods have been adapted from ETR 027 [3] where possible.
The type of equipment covered by this ETS is handportable stations with integral antennas.
This ETS covers angle modulation to be used for radio equipment, but individual national administrations
are free to choose the type of modulation. Channel separations, maximum transmitter output
power/effective radiated power and the inclusion of automatic transmitter shut-off facility may all be
conditions attaching to the issue of a licence by the appropriate administration.
This ETS is complementary to ETS 300 086 [2] which covers radio equipment with an internal or external
RF connector, for use in the land mobile service. It is primarily intended for omnidirectional applications.
Equipment which also includes an external or internal RF connector should be type tested to the
requirements of ETS 300 086 [2] using this connector.
Additional standards or specifications may be required for equipment such as that intended for connection
to the Public Switched Telephone Network (PSTN).
This ETS does not cover requirements for radiated emissions below 30 MHz.
This ETS may also be used by accredited test laboratories for the assessment of the performance of the
equipment. The performance of the equipment submitted for type testing should be representative for the
performance of the corresponding production model. In order to avoid any ambiguity in that assessment,
this ETS contains instructions for the presentation of equipment for type testing purposes (clause 4),
conditions (clause 6) and measurement methods (clauses 8 and 9).

3 Definitions, abbreviations and symbols
3.1 Definitions
For the purpose of this ETS, the following definitions apply:
angle modulation: Either phase modulation (G3) or frequency modulation (F3).
audio frequency load: The audio frequency load is normally a resistor of sufficient power rating to accept
the maximum audio output power from the equipment under test. The value of this resistor should be that
stated by the manufacturer and equal to the impedance of the audio transducer at 1 000 Hz. In some
cases it may be necessary to place an isolating transformer between the output terminals of the receiver
under test and the
