PK-88 OPERATING MANUAL
PASSALL ON|OFF
Parameters:
ON
-
The PK-88 will accept packets with invalid CRCs.
OFF -
The PK-88 will only accept packets with valid CRCs.
PASSALL permits the PK-88 to display packets received with invalid CRC fields; the
error-detecting mechanism is turned off.
Packets are accepted for display despite CRC errors if they consist of an even
multiple of eight bits and are up to 330 bytes. The PK-88 attempts to decode the
address field and displays the call sign(s) in the standard monitor format, followed
by the text of the packet.
PASSALL is normally turned off; therefore, the protocol ensures that received packet
data is error-free by rejecting packets with invalid CRC fields.
PASSALL (sometimes called 'Garbage Mode') may be useful for testing a marginal RF link
or during operation under other unusual conditions or circumstances.
When you set PASSALL ON while monitoring a moderately noisy channel, 'packets' are
displayed periodically because there is no basis for distinguishing between actual
packets and random noise.
When PASSALL is ON, logging of stations heard (for display by
MHEARD) is disabled; the call signs detected may be incorrect.
