AXDELAY
Mode: Packet
n
Parameters:
-
AXDELAY
specifies the period of time the PK-232 will wait – in addition to the delay set by
LAY
– after keying the transmitter and before data is sent.
Packet groups using a standard "voice" repeater to extend the range of the local area network may
need to use this feature.
Repeaters with slow electromechanical relays, split sites, auxiliary links (or other circuits which de-
lay transmission after the RF carrier is present) require more time to get RF on the air.
If you're using a repeater that hasn't been used for Packet operations before, try various values to
find the best value for
If other Packet stations have been using the repeater, check with them for the proper setting.

AXHANG
Mode: Packet
n
Parameters:
-
The numeric value can be used to increase channel efficiency when an audio repeater has a hang
time greater than 100 milliseconds. For a repeater with a long hang time, it is not necessary to
wait for the repeater keyup delay after keying the transmitter if the repeater is still transmitting.
When the PK-232 has heard a packet sent within the hang period, it does not add the repeater

BAUDOT
Mode: Command
BAUDOT
is an immediate command that switches the PK-232 into the Baudot mode. Baudot opera-
tion is still the most common form of RTTY operation in use around the world, and is the basis of
the worldwide telex network and most radio press and weather services. The Baudot/Murray and
ITA #2 character sets do not contain lower case or the special punctuation and control characters
found in the ASCII character set. Because the Baudot/ITA #2 code requires only five information
bits to define each transmitted or received character, under worst-case conditions, Baudot RTTY
will generally suffer fewer errors than ASCII code at the same data rate.
