the Patrol Craft will need to communicate, together with the means

of communications available). To meet the various requirements in the

table it was proposed the following equipments be fitted:

(1) Two RAF/RN Voice equipments (one for inter-

operability with military aircraft and one for use

between Patrol Craft operating in company with each

other).

(2) One civil aeronautical voice equipment (combined

with one of the RAF/RN equipments above).

(3) One civil maritime voice equipment.

(4) One military voice equipment (identical to,

but in addition to the set provided for local

command and control).

The other requirements could be met using the equipments provided for

command and control communications. Should the RHKP purchase a commercial

security device for their marine craft, then the same device would be

required for the Patrol Craft, who would already have similar radios

(items (3) and (4) above) capable of the requisite adaptation.

Direction Finding. Two types of SAR operations were predominant in

the Hong Kong SAR region: civil aircraft and merchant ships. Unfortunately

they employed different communications equipment and hence searching for

them required different equipment. Moreover, the problem of finding a

downed aircraft or ship in distress, usually in adverse weather conditions,

was one of the most difficult aspects of SAR. Every available aid to local-

isation was highly desirable and for this reason it was proposed that two

direction finding equipments, one for each role, were fitted.

8. Shore Radio Equipment. In addition to the equipment installed in the

Patrol Craft the following radios would be required ashore:
