Mode: packet
I to 15,
specifying timeout
in
I second intervals.
FRACK is
the
FRame
ACKnowledgment time in seconds that
your
PK-96
will
wait
for acknowledgrnent
of a sent
protocol
frame before
"retrying"
that frame.
After sending a
packet
requiring
acknowledgment, the PK-96
waits for FRACK
seconds
befbre
increasing
the retry
counter and sending another fiame. If the
packet
address includes any digipeaters,
the time be-
tween retries is
adjusted to:
Retry interval
(in
seconds)
=
n x
(2
x m+l), where
"m"
is
the
number
of
intermediate
re-
lay stations.
When a
packet
is retried,
a random wait time is added to any other wait times. This avoids lockups
whcre
two
packet
stations repeatedly collide with
each other because of timing conflicts.

0 to
250,
specifying the FRACK timeout for meteor scatter work in l0 mS increments.
FRICK
is a short version of
FRACK,
meant
to be used in
packet
radio meteor scatter work.
If FRICK is
0
(delault),
the FRACK timer is
then used and the PK-96 operates as before
with
the retry timer
in
units of
whole
seconds. If FRICK is
I to 250, it ovenides FRACK as
the unit's
retry timer, and the retry timer is in
units of l0 mS
up to 2500 mS
(2.5
seconds).
Unlike FRACK, FRICK
doesn't take into account
the
number
of digipeaters in the connect
path.
FRICK
assurres that no
digipeaters are being used.
Ncnn:
Do not attempt
multiple
packet
connections vvhile FRICK
is
qctive
(I-250).
In
contrast
to FRACK vvhich
provides
one retry timer per
multi-connect channel, there is only
one
FRICK timer in the PK-96.
Each
channel will
try to use the same FRICK
time4 causing interference to the operation of the other channels.
Due
to the sporadic nature
of
meteor
scatter work, a Master/Slave mode
can
be enabled in the FK-96 with
User BIT

(UBIT
74. With
UBIT
/B
OFF, FRACK operates the same as before.
