1 Introduction
Plextek’s Blighter B202 Radar has CE(!) approval and FCC certification to allow it to be sold into the
European and American continents respectively. In most countries it is necessary for the operator of the
equipment to acquire a Transmission Licence from the national spectrum management authority. In the UK
this is OFCOM and in the USA, the FCC.
Each licensing authority asks for specific characteristics of the transmitting equipment. This document
provides the majority of information required by most authorities.

Please note
no te that this information must not be freely distributed. It may only be supplied to the
relevant licensing authority and wherever possible, the licensing authority should also be asked to
restrict the distribution of the information.

3 Derivations

3.1 Power
Theoretical Peak Radiated Power (EIRP) = Peak Power (+1dBW) + Maximum Antenna gain (+24dBi)
Theoretical Mean Radiated Power (EIRP) = (Peak Power (+1dBW) + Maximum Antenna gain (+24dBi)) +
Duty Cycle (10log10 (84%))

0dBW ERP = +2.14dBW EIRP (ERP radiated power relative to a dipole antenna)

Therefore ERP (dBW) = EIRP (dBW) -2.14dB

Mean Effective Radiated Power (ERP) = Peak Power (+1dBW) + Maximum Antenna gain (+24dBi) + Duty
Cycle (10log10 (84%)) – 2.14dB

3.2 Emission Designator
26M0Q3N where;

First four digits define the necessary bandwidth:

26.0MHz = 26M0

Last three digits define emission class:

Q - In which the carrier is angle modulated (FM) during the period of the pulse
3 - A single channel containing analogue information
N - No information is transmitted
