Overview

2-4 HF SSB transceiver user guide

Selective call (where fitted)

Selective calling simplifies calling stations. Each transceiver

has its own address rather like a telephone number. You call a

station by specifying its address. If the station is unattended,

your call details are automatically recorded. Selective calling

saves you from having to listen to noise when waiting for a

call.

Selective calls consist of ALE calls, beacon calls, GPS calls,

page calls, selcalls, status calls and telcalls. Selcall is the

basic type of selective call for voice communication.

GPS position calls, page calls and selcalls allow you to call a

range of stations simultaneously by group calling. This is

useful for base stations wanting to contact all mobile stations

or for starting a conference discussion between several

stations.

To change the call to a group call, you end the address with

00. All stations with matching addresses, excluding the last

two digits, will receive your call. For example, a call to

123400 will be received by all stations with addresses in the

range 123401–123498.

Your transceiver can store information from 10 stations that

have called you while your station was unattended.

Paging (where fitted)

The transceiver has a paging feature that allows you to send

and receive text messages up to 64 characters long.

You can either send messages directly from the control panel

or from an attached computer terminal. Received messages

are displayed and recorded in the call memory of the

transceiver.
