MFJ-1278B MULTI-MODE BASIC OPERATION
CW CONTEST MEMORY KEYER OPERATION
For CW enthusiasts who like to use a key paddle to send CW, the MFJ-1278B provides an
input for an iambic key paddle. See CW KEY PADDLE INSTALLATION in chapter 3 in
this MFJ-1278B manual for installation of your iambic key paddle.
Sending CW with External Key Paddle
The MFJ-1278B sends key paddle generated CW at 5 to 99 WPM.
The transmission speed for key paddle CW defaults to the same speed as keyboard CW, 20
WPM. The user can change the transmit speed by changing the MSPEED command. To set
the MFJ-1278B to 15 WPM, you would type:
MSPEED 15 <ENTER>
Be sure you are in command mode when issuing the MSPEED command.
It is always a good idea to match your CW transmit speed with the person to whom you are in
QSO with. The MFJ-1278B makes it easier for you to match your transmit speed to someone
else's through the CWSPEEDM command. The CW speed matching feature causes your
MFJ-1278B to adopt the speed of the received CW as it's transmit speed. When the
CWSPEEDM command is ON, then the MFJ-1278B will match it's CW transmit speed with
the whatever speed was last locked to through the AUTOTRAC routine. The MFJ-1278B
will also adopt whatever transmit speed is locked-in by the ALOCKCHAR character,
CTRL-U will also be
The CWSEndch (nnn) command provides the user more flexibility in controlling how
CW/MCW characters are transmitted from the key paddle. The CWSEndch command is
only effective for CW and MCW modes.
The user needs to leave the CWSEndch command at the default value of 255 or $FF, when
sending CW using a key paddle. The MFJ-1278B will transmit all CW characters
immediately if the CWSEndch command is at the default setting of 255 or $FF. Once the
MFJ-1278B completes the CW transmission, the MFJ-1278B will revert to the receive mode.
Buffer transmission in the Memory Keyer Mode is the same as in the CW mode. Weighting
of key paddle CW is achieved by using the WEIGHT command. Please refer to the CW
mode section as to setting of the WEIGHT command.
