When testing on the distress/safety frequency is unavoidable, it should be indicated that these are test transmissions. Normally the test call would require no further communications between the two stations involved. e Select the desired coast station code, then push [ENT]. · Use [CH] to select the coast station code when pre-programmed. ********* Test ********* ------ Address ID -----ÇM a n u a l s e t 001234567 Port ICOM 001234566 Port ABC 001234565 Port M802 SEL OK t The calling stand-by screen is displayed as follows, verify the calling condition then push and hold [CANCEL/CALL] for 1 sec. to transmit the test call. ********* Test ********* --------- Call --------To:007654321 2187. 5kHz Call Freq:TX RX 2187. 5kHz Call y After sending a call, the transceiver waits for an acknowledgement.

Therefore, the transceiver must set to DSC watch mode to decode these calls. D When receiving a DSC call One of the following actions should be performed when a DSC call is received depending on the received DSC format (or category): · Wait for a voice transmission on the traffic frequency. · Transmit an acknowledgement with DSC or voice. D Display example and operation · Monitoring the traffic frequency Monitor the communication between the calling ship and a coast station, or the calling station transmission via voice on the traffic frequency. · Emergency alarm sounds until pushing [CANCEL/CALL], or short beeps sound, depending on the calling format or category. ************************ Distress RLY * * 123456789 * * ************************ Exit Traffic ************************ Distress * * 123456789 * * ************************ Exit Traffic ************************ All ships * * 123456789 * * ************************ Exit Traffic ************************ Geographic Grou * * ICOM 6789 12345M802 * * ************************ Exit Traffic ************************ Geographic * * 123456789 * * ************************ Exit Traffic · Transmit an acknowledgement When the following DSC is received, an acknowledgement must be sent back to the calling station. · Short beeps, or an emergency alarm sounds until pushing [CANCEL/CALL], depending on the category. ************************ Individual * * ICOM M802 * * ************************ Exit Traffic ************************ Position REQ * * ICOM M802 * * ************************ Exit ACK 7 8 37 8 WHEN RECEIVING A CALL I Received information When receiving a DSC call, the received format specifier and its contents are memorized into the RX memory. Distress calls (including other calls with a distress category) are stored separately from other calls. Up to 20 distress and up to 10 other categories of call can be memorized. [. . . ] It may also be recommended by local experts to tie in the aluminum mast to this close proximity keel bolt for lightning protection. The run from the mast to the keel bolt must be smooth, direct, and without sharp turns in order to pass lightning energy effectively into the underwater lead. Steel-hulled vessels are easily attached to with foil by scraping away any protective coating from the hull, and making a low resistant good surface area contact. Non-metal hull or keel boats require yards and yards of foil to be run below the waterline, anywhere you can, and picking up any other large below the waterline tanks and tubes. SUMMARY If you follow these steps, you will have an outstanding single sideband signal that can be heard around the world. [. . . ]
