11.6.2 Calling CQ In Unproto Pactor
If you plan to make a CQ call, you must do so in the unproto Pactor mode.
This is required since an ARQ Pactor transmission requires another station to 'Link-up"
with. If you are using a Timewave terminal program, see the program manual to place the
PK-232 into unproto transmit. If you are using a terminal or terminal emulation program,
the following will place your PK-232 and transceiver into the transmit mode.
o Type PTSEND then press the <Enter> key to key your transmitter and automati-
cally enter Pactor unproto transmit mode.
As soon as you type the <Enter> key you will be transmitting. At this point you are
also in the CONVERSE mode and anything you type will be sent in unproto Pactor by
your transmitter.
o Type in your CQ message. Make sure you include YOUR Callsign. An example is
shown below:
CQ CQ CQ CQ CQ CQ CQ DE N7ML
CQ CQ CQ CQ CQ CQ CQ DE N7ML
CQ CQ CQ CQ CQ CQ CQ DE N7ML
CQ CQ CQ CQ CQ CQ CQ DE N7ML K
<CTRL-D>
o Type <CTRL-D> at the end of your CQ call. The <CTRL-D> puts your radio into the
receive mods and your PK-232 into the Pactor standby mode where it is ready for a
call.
Pactor standby is different from the Pactor Listen mode. In Pactor standby, your PK-232 is
ready to receive Pactor connects, but you will not be able to monitor other Pactor sta-
tions.
o Wait a bit to see if you get a response. Your transmitter will begin to key on and off
and you will see a CONNECTED message when someone calls you in Pactor. If you
do not get a response, you can repeat the above procedure or you can go look for
other Pactor stations as described in the next section.
11.6.3 Answering an Unproto Pactor CQ
You must be in the Pactor Listen (PTL) mode to monitor other Pactor stations. When you
are in the Pactor Listen mode, you can monitor both the 1 second "chirps" of connected
Pactor stations, and the continuous transmissions of unprotocol Pactor stations calling CQ.
Normally when you see a station calling CQ in unproto Pactor, you will want to answer him
using ARQ Pactor. Remember that ARQ Pactor is the protocol that has the smallest chance
of transmission errors.
Let's assume you hear N7ML calling CQ. To answer, do the following:
o If you are using the Timewave or AEA PAKRATT for WINDOWS program, check the
program manual for instructions on starting an ARQ Pactor contact.
o If you are using a terminal or terminal emulation-program, simply type
PTC
N7ML<Enter> to start a Pactor contact. After your PK-232 has locked or synchroni-
zed with the distant station, which will be indicated by the LED display changing
