MFJ-1278B MULTI-MODE OPERATIONAL COMMANDS

CWCALL ssss

Mode: Amtor Default: blank


Where "ssss" are 15 characters sent as CW when you issue the ID character. The "ssss" text
is sent following the QRA ("The name of my station is ______") signal.

CWidmode nn: 0<=nn<=255

Mode: Pactor Default 0


Should CW identification be required, the MFJ-1278B now supports 8 CW identification
modes. Seven automatic modes are selected by the bit-mapped CWIDMODE parameter.
Bit positions within the CWIDMODE parameter enable timed cw id, cwid on incoming
events, cwid on outgoing events,
and any combination of the three for a total of 7 modes.

The timed mode requires some explanation. The counter controlling the transmission of the
timed CWID must be initially started at the beginning of each link with either the manual
"ID" command or one of the initial CWIDMODE features selected by CWIDMODE bits 1
or 2. A fully automatic CW ID is achieved by setting CWIDMODE to 3. Reduced levels of
automation are selected by other combinations. The eighth mode is manual cwid. Invoke
manual CWID by issuing the "ID" command. Also see IDTIME

The CWIDMODE command in Pactor is very complex and provides several combinations of
CWID. Below is an example of how CWIDMODE functions:
