Download PK-900 Packet Controller Operating Manual

FRICK timer can be set from 0 (disabled) to 250 which corresponds to
a time of up to 2.5 Seconds. See the Command Summary for a complete
description of the FRICK timer.
The following settings are recommended for this method of Meteor
Scatter work. Both packet stations should use these same settings.
UBIT 18 ON
RETRY 0
AX25L2V2 ON (default)
MAXFRAME 1
(CHECK doesn't matter)
FRICK n, where n is large enough to allow the other station time
to send the start of an acknowledgement frame
Note: Do not operate the unit with multiple packet connections while
FRICK is active (1-250). In contrast to FRACK, which provides
one retry timer per multi-connect channel, there is only one
FRICK timer on each radio port of the PK-900. Each logical
channel will try to use the same FRICK timer, causing
interference to the operation of the other channels.
Digipeaters should not be used when in the Meteor Scatter mode.
The FRICK timer (unlike FRACK) does not allow any extra time when
digipeater stations are specified.
To return to normal AX.25 packet operation turn User BIT 18 OFF.
Also, be sure to disable the FRICK timer (by setting FRICK to 0)
when you are through operating in Meteor Scatter mode.
