How to make a voice call
Here follow a number of rules you should observe when
making a voice call on your HF-90 radio (or any HF/SSB
radio):-
Select the appropriate channel (according to its
frequency).
Before voice calling the other station, listen to the
channel to see if it is busy. If the channel is busy you
should wait until communications have ceased. If the
channel is free you can proceed with your call.
Press and hold down the PTT switch on your
microphone/handset and give a long voice call (5-10
seconds), indicating the station you are calling on.
“Perth base, Perth base, Perth base, this is Mobile 5ABC, Mobile
5ABC, Mobile 5ABC, calling on Channel 50 - Over”.
Please note this is also the recommended method of
voice calling any Telstra Radphone Station or RFDS
(Royal Flying Doctor Service) Station
(relevant only to
users within Australia).
It is better if you can end all of your communications
with the word “OVER”. This indicates clearly to the
other user that you have finished what you wish to
say, so that they may speak. This is very important,
particularly when you are speaking to someone who
is on a telephone (via a telephone interconnect unit).
