Frequency Assignment Principles

ensure that the assigned frequency lies within the tuning range of the available equipment

prioritize users and services and select the less noisy spectrum for frequency assignment of critical or sensitive-low power services (e.g. telemetry)

assign only 12.5 kHz channels for PMR and 10 (30) MHz channels for digital (analog) cordless cameras

Frequency Assignment Principles

decide upon TX (or RX) spectral isolation in each service and between different services

ask from professionals (broadcasters) that isolators should be fitted to all continuous transmission Base Stations

ask for the use of CTCSS subtones in order to increase group privacy and avoid receiver squelch opening

Frequency Assignment Statistics

7618 applications licensed

Only 1.65% applications rejected

95% of frequency assignments within equipment tuning range
