by "calling CQ" or by answering a "CQ" call by another station.
6.4.1 Calling CQ
To call CQ first you must tell your PK-900 to start transmitting.
o Type "X" to key your transmitter and start the PK-900 sending.
o Type in your CQ message (use YOUR callsign) such as the one below:
CQ CQ CQ CQ CQ CQ CQ DE YOURCAL YOURCAL YOURCAL
CQ CQ CQ CQ CQ CQ CQ DE YOURCAL YOURCAL YOURCAL
CQ CQ CQ CQ CQ CQ CQ DE YOURCAL YOURCAL YOURCAL
CQ CQ CQ CQ CQ CQ CQ DE YOURCAL YOURCAL YOURCAL K
<CTRL-D>
o Type <CTRL-D> at the end of your CQ call. The <CTRL-D> puts both
your radio and the PK-900 into the receive mode.
o Wait a bit to see if you get a response. If not, you can repeat
the above procedure.
6.4.2 Answering a CQ
Let's assume you hear KZ7G calling CQ. To answer, do the following:
o Type "X" to key your transmitter and start the PK-900 sending.
o Call the other station by giving his call followed by your call,
(KZ7G DE YOURCAL). Start the transmission with a line of RYs as
a tuning signal for the distant station. Here's an example:
RYRYRYRYRYRYRYRYRYRYRYRYRYRYRYRYRYR
KZ7G KZ7G KZ7G DE YOURCAL YOURCAL YOURCAL
KZ7G KZ7G KZ7G DE YOURCAL YOURCAL YOURCAL
KZ7G KZ7G KZ7G DE YOURCAL YOURCAL YOURCAL
<CTRL-D>
(If the other station can't copy these four lines of text, the
chances are he won't copy any more than that. No need to waste
time and bandwidth by typing 15 or 20 lines of the same thing.)
o Type <CTRL-D> at the end of your call. The <CTRL-D> puts both
your radio and the PK-900 into the receive mode.
Always end every transmission with a carriage return to force the
distant station's screen cursor or teleprinter back to the left margin
on a new line. It's a good operating habit that keeps things neat.
o Wait a bit to see if you get a response. If not, you can repeat
the above procedure.
