One other question that comes up from mariners from time to time is why some
manufacturers refer to HF channels as “6A,” “4B,” and so forth. The “A” stands for the
first simplex channel within a particular marine radio band when counted from lowest
to highest frequency. Channel 6A would be ITU channel number 650 on a simplex
frequency of 6215.0 KHz. This is also the 6 MHz band Distress frequency. Similarly,
channel 4B would be 4146.0 KHz, the second simplex frequency on the 4 MHz band
better known as ITU channel 451.
Channels 1-99 displayed on the SG-2000 are user defined.
Channels 100-200 may be factory assigned.
Channel numbers over 200 refer to the official ITU channel number .
