C. CONFIDENTIAL: Ha
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:
(1) Local Command and Control Net:
