Selcall lockout
Before you can use selcall lockout, you need to make sure
that use of this facility is switched on (refer to the HF SSB
transceiver reference manual, Chapter 8, Selcall lockout
on/off).
Selcall lockout prevents you from sending selective calls if
the transceiver detects that another station is already in the
process of sending a selective call on the same channel. This
reduces call interference between stations and increases the
chance of success when your call is transmitted.
Selcall lockout does not apply to voice, tone or emergency
calls.
When selcall lockout occurs, the transceiver:
• beeps softly twice
• displays the error message ‘
Busy: Call is active
’ for two
seconds.
