MFJ-1278B MULTI-MODE BASIC OPERATION
If CWSEndch is left at the default setting of 255 or $FF, the MFJ-1278B will transmit all
characters immediately when typed. The requirement for pressing the <ENTER> is
eliminated.
characters immediately when typed. The requirement for pressing the <ENTER> is
eliminated.
Note
: If you are using a terminal program such as "PROCOMM" for IBM PC and
compatibles that buffers the transmit data, then a CARRIAGE-RETURN will be
needed to transmit.
needed to transmit.
The MFJ-1278B employs full CW break-in for transmitting in the CW/MCW modes. The
CWSEndch command enables the full CW break-in feature. Setting the CWSEndch to
something other than the default, will disable the break-in feature. Users do not have to press
Ctrl-R to force the MFJ-1278B to receive or to press Ctrl-T to force the MFJ-1278B to
transmit. MFJ-1278B will always go back to receiving mode at the end of each transmission.
CW break-in is effective for both CW and MCW mode.
Transmitting from Memory Buffers
The user can use the BUFKEY (nnn) command to define a particular key to transmit the
memory buffers. The MFJ-1278B uses the TAB key, ($09) as the default for the BUFKEY
command. The user can transmit any memory buffer, 0 through 9 by using the TAB and the
appropriate buffer number. For example, to transmit memory buffer 3, the user would press
the TAB key followed by the number 3 key. When pressing the TAB key, DO NOT hold the
TAB key down, just press it, then let up. Once the MFJ-1278B transmits the memory buffer,
the MFJ-1278B will revert to receive mode. There is no need to issue a CTRL-R to make the
MFJ-1278B go back to receive mode.

Note
: If you are using MFJCOM terminal program, you will not be able to use the "TAB"
key as the BUFKEY. Change BUFKEY to another key on the keyboard. See
BUFKEY command in Chapter 6 for more detail.

CW Weighting
The MFJ-1278B allows you to increase or decrease the weight of the code elements
generated by the keyboard or key paddle. The user can set the WEIGHT by using the
WEIGHT command. The weight factor defaults to dot-to space ratio of 1:1. A number from
0 thru 255 represents the weight value used. The default setting of the WEIGHT command,
0 sets a weight factor of 1:1. Select a number from 1 to 127 to INCREASE the dot/space
ratio. Select a number from 128 to 255 to DECREASE the dot/space ratio (weight). You can
easily change the weight the MFJ-1278B uses by typing:
