Using selective call
9480 HF SSB transceiver 5-23
Using the beacon feature
The beacon facility is used to check signal conditions
between two transceivers fitted with selective call.
The beacon facility has two modes of operation:
• selective beacon mode
• base station (99) beacon mode.
Selective beacon mode
When the beacon facility is enabled, the transceiver
transmits a beacon signal on receiving a selective beacon call
from another transceiver. Refer to page 5-25, Selective
beacon mode.
Both transceivers must be on the same channel, or the
receiver of the selective beacon call must be scanning
through the same channel.
(99) beacon mode
The 99 beacon mode is recommended for use in base station
applications and for those transceivers that may have
operating selective call but do not have the beacon mode
facility.
When a base station is enabled for beacon mode, the
transceiver transmits a beacon signal on receiving a selective
call ending in 99. Refer to the (99) beacon mode procedure
on page 5-27.
The thousand and hundred digits of the address must be the
same for both the beacon transmitting and receiving stations.
If mobile transceivers have the beacon enabled, the first two
digits of each mobile transceiver’s self-identification address
should be set to a different number so that they do not all
transmit a beacon response together.
