PTFecspd 100 | 200
Default 100
This command will set the speed to be used for PACTOR FEC transmissions. When set to 100, all
FEC transmissions will be at 100 baud and when set to 200, FEC transmissions will be at 200 baud.
PTHuff ON | OFF
Default OFF
When ON, allows Huffman compression of 7-bit data when operating PACTOR. The KAM Plus will
automatically detect any 8-bit data and will not apply compression if any 8-bit data is contained in
the frame being transmitted. It will also not compress unless the compression will result in greater
throughput. When OFF, Huffman compression is disabled.
PTListen
Immediate command
Places the KAM Plus in the PACTOR Listen Mode. This mode will allow 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 information will be trans-
mitted
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 exchanged 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 Plus 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 Plus 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 Plus 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
Sets the maximum number of attempts to increase a PACTOR link to 200 baud. If unsuccessful
after
n
attempts, the KAM Plus will remain at 100 baud until it receives PTUP consecutive good
frames.
PTUp
n
(
n
= 2 – 30)
Default 3
Sets the number of consecutive good PACTOR frames that must be received before requesting a
switch to 200 baud PACTOR.
