Repeaters
– a repeater system consists of a linked
transmitter/receiver combination installed in a
prominent location. The repeater is designed to
receive signals on a designated channel and
re-transmit them on another channel. Repeaters
are normally located on hills, mountains or tall
buildings.
SSB
– single sideband comes in three modes AM, USB
(upper side band) and LSB (lower side band).
The SSB is better for long distances and/or when
signals are weak as power is directed to one
sideband and the radiated power is increased.
Selcall
– this stands for selective calling to
selectively call a friend over the air. The
transceiver is factory programmed with its own
unique Selcall Identification Number (Ident).
This number identifies your radio from others in
your area. So you need to make your Ident known
to anyone who may need to call you with
Selcall. When your Ident number is called your
transceiver will beep to alert you.
Radphone
– or ‘radio telephone’ is where a connection is
made with the public telephone network from a
base station you call over a suitably equipped
HF radio. A service fee and call costs apply. A
selcall is made to the provider’s base station,
then key in the telephone number on the radio
interface
and commence the call when answered.
Conversations are not private.
