Alist; Amtor; Arq - AEA PAKRATT PK-232 Operating Manual

USER'S GUIDE

ALIST

Mode: AMTOR
ALIST
is an immediate command that switches your PK-232 into the ARQ Listen mode.
You can usually monitor a contact between two linked stations by using the ARQ Listen mode (also
called Mode L). This mode may need a few seconds to phase or acquire synchronization with the
other stations. Your ability to synchronize with the master station depends on operating conditions
such as interference.
If the link stations that you are monitoring are experiencing ARQ errors and retries, your monitor
will display all retries.
Type ALIST (or AL) repeatedly if you lose synchronization.

AMTOR

Mode: Command
AMTOR
is an immediate command that switches your PK-232 into the AMTOR mode. Your PK-232
is automatically placed in ARQ Standby condition.
Your station is then available for automatic access by and response to any AMTOR station that
sends your SELCALL.
Your monitor will now display any inbound FEC (Mode B) transmissions on the received channel
without any additional action on your part.

Mode: AMTOR

Parameters: - The distant station's SELective CALling code.
ARQ
is an immediate command that starts an AMTOR Mode A (ARQ) SELCALL (SELective CALL) to
a distant station.
Example:
The SELCAL started by the ARQ command is the proper method of responding to another station's
Mode B (FEC) CQ call.
To begin the Mode A (ARQ) selective call:
Type ARQ followed by the other station's four-character SELCAL.
The distant station's SELCAL code is normally seen as part of the his/her CQ call sequence.
As soon as a <CR> is typed, your PK-232 will begin keying your transmitter in the three-character
AMTOR ARQ burst sequence. If the distant station receives and decodes your selective call suc-
cessfully, the two AMTOR systems synchronize and begin the Mode A (ARQ) AMTOR "handshak-
ing" process.
