301. RECEIPT METHOD<br />
CHAPTER 3<br />
RECEIPT METHOD – PROCEDURES<br />
SECTION I – RECEIPT METHOD<br />
a. The receipt method requires the receiving station to give a receipt for each message to<br />
the transmitting station; thus there is certainty of reception. It may be accomplished by stations<br />
transmitting on the same frequency, or on different frequencies. It is normally used when passing<br />
messages:<br />
(1) Between fixed stations.<br />
(2) From a mobile to a fixed station.<br />
(3) From a mobile or fixed station to an aircraft.<br />
(4) Between mobile stations.<br />
b. Under difficult conditions, when no answer to a call can be obtained, a message may be<br />
transmitted in the hope that it may be received. Subsequent to this blind transmission every effort should<br />
be made to obtain a receipt (see para 319).<br />
c. For passing messages from shore stations to ships, methods are preferred which do not<br />
entail the ship breaking <strong>radio</strong> <strong>communication</strong>s silence (see para 401).<br />
