PK-232 OPERATING MANUAL Pactor OPERATION
<CTRL-Z> is the character defined by the PTOVER command that
switches your system from being the Information Sending Station
(ISS) to the Information Receiving Station (IRS) and switches the
distant system from being the information receiving station to
the information sending station. This single character operates
like the “+?” does in AMTOR.
The FCC requires station identification once every ten minutes. It's
sufficient to begin with “QRA (mycall)" or end your transmission with
"QRA (mycall)” before the "<CTRL-Z>” changeover, or use the <CTRL-B>
“HERE-IS" to send your own Auto-AnswerBack message. For the "HERE-IS"
command to function, you must have your AAB text entered.
See appendix A for the AAB command.
11.6.3.1 Ending An ARO Pactor Contact
When you've finished your “final finals”, to the distant station and both
stations are ready to end the Pactor ARQ contact, you can end the contact
and terminate the link in several different ways:
•.
Type <CTRL-D> to stop sending after the transmit buffer is empty.
<CTRL-D> breaks the link and returns your PK-232 to Command Mode in
Pactor Standby. This is the best way to end a Pactor contact.
• Type <CTRL-F> to stop sending after the transmit buffer is empty,
send your Morse ID, and return to Pactor Standby and Command Mode.
• Transmitter and returns to Pactor Standby and Command Mode. This
is the best way to end a contact if you want to identify your
station in Morse code as well.
• Wait until all the text has been sent, then type <CTRL-C> to return
to Command Mode, then type "R” to break the link. The PK-232 will
then go into the Pactor Standby mode.
• Type <CTRL-C> to return to Command Mode, then type "R <Enter> R
<Enter>" to break the link immediately If there are characters left
in the transmit buffer, they will not be sent. This method should
onlv be used for an emergency shutdown as it does not send the
control signal to the other station that informs it you are
shutting down. As a result the other station will continue to send
until it's internal timer turns it off.
11.6.4 Long Path Contacts
If the station you are going to call is more than half way around the
earth i.e. a long path contact, precede that station's callsign with an
exclamation point. The will change the Pactor timing to allow for the
extended radio propagation delay. You would type:
PTCONN !N7ML <Enter>
If your station doesn't link within a period of time determined by the
ARQTMO command (default 60 seconds), your station will automatically
stop transmitting.
