Mode B (FEC) Operation
To operate Mode B AMTOR, you must first be in the Command mode (cmd:).
Type FEC and press return. This places the KAM’98 in the FEC mode without
sending any message to your terminal. In this mode you can receive any FEC
transmissions made by another station or transmit FEC from your station. Since
FEC can be copied by several stations at the same time, you would use this mode
to have a conversation with numerous stations at the same time (a round-table
discussion). NOTE: If AUTOSTRT is ON, you will only monitor SELFEC trans-
missions from other stations that contain your SELCAL in the transmission.
To transmit Mode B, type <Ctrl+C> T. This keys your radio, the bargraph on the
KAM’98 goes dark, and the red transmit LED lights. Type the message you want
to send. At the conclusion of your message, type <Ctrl+C>E. Your KAM’98 will
transmit your message in FEC mode and return to the receive mode when all of
the data has been transmitted.
Mode B (SELFEC) Operation
Receiving Mode B SELFEC
If you want to receive messages addressed just to you, set up the KAM’98 for
Mode B SELFEC receive. To do this, set the AUTOSTRT command ON in your
KAM’98, then enter the AMTOR Standby mode or the FEC mode as described
above. Your KAM’98 will now copy only Mode B SELFEC transmissions that
include your SELCAL in the transmission.
