MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS
Parameters:
nnn: 0<=nn<=255
The Pactor PASS command is the same as the PASS command in the other modes. The
PASS command does not work for ^Y Changeover.
PASSALL ON/OFF Mode: Packet Default: OFF
Parameters:
ON The MFJ-1278B will accept packets with invalid CRCs.
OFF The MFJ-1278B will only accept packets with valid CRCs.
This command causes the MFJ-1278B to display packets received with invalid CRC fields.
Packets are accepted for display despite CRC errors if they consist of an even multiple of 8
bits and up to 339 bytes. The MFJ-1278B will attempt to decode the address field and
display the callsign(s) in the standard monitor format, followed by the text of the packet.
This mode is not normally enabled, since rejection of any packet with an invalid CRC field is
what insures that received packet data is error-free. This mode might be enabled for testing a
marginal RF link or during operation under other unusual circumstances.
If you set PASSALL ON and monitor a moderately noisy channel you will periodically see
"packets" displayed in this mode, since there is no basis for distinguishing actual packets
received with errors from random noise.
Logging of stations heard (for display by MHEARD) is disabled whenever If PASSALL is
ON, since the callsigns detected may be incorrect.
