PK-232 OPERATING MANUAL Pactor OPERATION
11.7.2 Entering Your Auto-AnswerBack (AABI
Timewave Pactor allows you to request the identity of the station you are
conversing with by sending your PK-232 a <CTRL-E>. This causes the PX-232
to send an inquiry Who aRe YOU (WRU) request to the other station.
For this reason, you should set your own Auto-AnowerBack (AAE) message to
“DE YOUR-CALL". Your PK-232 will automatically send the AAB message when
another station requests your identity, and then stop sending.
11.7.3 Operating Pactor with Other Modem frequencies and Shifts
All Pactor operation uses 200 Hz shift PSK tones as does HF packet.
11.7.4 Automatic Speed Change
If the command PT200 is set on, the linked Pactor mode will automatically
change the transmitted data rate from 100 bps to 200 bps if a certain
number of error-free 100 bps packets are received in a row. If the error
rate at 200 bps is excessive, the data rate will automatically revert to
100 bps. There may be some propagation conditions that will cause the
system to vacillate between the two data rates. This may be prevented by
setting PT200 to OFF, which will force 100 bps operation.
11.7.5 Echoing Transmitted Characters As Sent (EAS)
EAS (Echo As Sent) operates the same as in AltQ AMTOR. If EAS is ON, you
will see characters echoed to your screen only the first time your PK-232
sends them. If the data is not acknowledged by the receiving station and
is re-transmitted, the characters are not echoed again. With EAS OFF,
characters are echoed to you screen as you type them. With EAS ON:
• If the data scrolls across your monitor at an even rate, you can
assume that you have a good ARQ link.
• If the data hesitates or scrolls in “jerky" intermittent fashion,
that's generally a sign that the radio link is not very good.
• If the characters stop appearing on your monitor, the link is
failing or has failed. The STATUS display will tell you this by
showing ERROR or REQUEST nearly continuously.
11.7.6 Sending only Complete Words (WORDOUT)
Some Pactor users like to have their words sent out only when they are
complete. This allows the word you are currently typing to be edited as
long as you have not typed a <Space> character or punctuation. Turning
WORDOUT ON activates this feature. See the Command Summary for more
information.
