MARITIME SITOR OPERATION

All SITOR operation is 170 shift (LSB). When not sending traffic, most stations
run a CW ID tape keyed on the space frequency. Some foriegn stations send a 
burst of FEC (mode B) data rather than the CW ID. SITOR is the same as AMTOR 
used by amateurs.

SITOR frequencies are roughly as follows:

COAST STATIONS                 SHIPS

FREQ (chan) to FREQ (chan)     FREQ to FREQ

4350 (401)     4357 (415)      4140     4160
6492 (601)     6506 (629)      6230     6280
8705 (801)     8718.5 (828)    8300     8360
13071.5 (1201) 13100.5 (1259)  12490    12520
17197.5 (1601) 17232.5 (1671)  16660    16700
22561.5 (2201) 22595   (2268)  22112    22185

Traffic lists, weather and emergency info are sent FEC (mode B) and traffic and
news is sent ARQ (mode A). Some maritime activity is listed as follows:

WLO has 4 daily FEC broadcasts at 1530, 1130, 1730, and 2330Z.:
