scope:

The present document covers the minimum characteristics considered necessary in order to avoid harmful interference and to make acceptable 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.

The present document applies to angle modulation systems for use in the land mobile service, operating on radio frequencies between 30 MHz and 1000 MHz, with channel separations of 12,5 kHz, 20 kHz and 25 kHz, and is intended primarily for analogue speech.

In the present document different requirements are given for the different radio frequency bands, channel separations, environmental conditions and types of equipment, where appropriate.

The types of equipment covered by the present document are as follows:

- base station: equipment fitted with an antenna socket; - mobile station: equipment fitted with an antenna socket;

- handportable stations:

a) fitted with an antenna socket; or

b) without an external antenna socket (integral antenna equipment) but fitted with a permanent internal or a temporary internal 50 Ω R.F. connector which allows access to the transmitter output and the receiver input.

For the type of equipment defined in (b) the additional measurements which shall be made using the equipment antenna connected to the station (and not using any connector) are as follows:

- transmitter effective radiated power;

- transmitter radiated spurious emissions;

- receiver maximum usable sensitivity (field strength);

- receiver radiated spurious emissions.

Handportable equipment without an external or internal RF connector and without the possibility of having a temporary internal 50 Ω RF connector is not covered by the present document.
