This command places the KAM’98 in the Pactor Listen mode. This mode will al-
low you to copy FEC or ARQ (linked) Pactor stations, but you cannot transmit
from this mode. Use the <Ctrl+C>X directive to return to the command prompt.
PTRPT n (n = 2 - 5)
default 2
When transmitting an unproto Pactor FEC message (i.e., calling CQ), the infor-
mation will be transmitted n times. This is done to improve the chances of other
stations copying your message since FEC transmissions do not use memory
ARQ.
PTSI {ON | OFF}
default OFF
When OFF, supervisory information exhanged between two Pactor units is not
displayed on the terminal. When ON, supervisory information is displayed.
PTSUM n (n = 0 - 120)
default 5
When linked in Pactor, the KAM’98 will attempt to assemble up to n received
frames to obtain a valid frame. This process is called memory ARQ. When a
frame is received, the KAM’98 checks the CRC-16 checksum and if it is invalid,
that frame is stored in memory. The sending station will then repeat the frame,
and the KAM’98 will check again to see if the frame is completely correct. If not,
it will attempt to assemble a good frame by combining the frames received.
PTTRIES n (n = 0 - 9)
default 2
