MFJ-1278B MULTI-MODE BASIC OPERATION
If the AUTOTRAC command is OFF, then before the MFJ-1278B can copy the tuned-in
CW signal, it must be manually locked to the speed of the received signal. To manually
lock the MFJ-1278B to the incoming signal, type a CTRL-U. The MFJ-1278B will respond
with "locking...". The MFJ-1278B will analyze the incoming CW signal. When the analysis
of the incoming CW signal is complete, the MFJ-1278B will respond with
"Locking...xxwpm." The "xx" is the speed of the received CW speed from 1 thru 99. When
the MFJ-1278B issues the response "Lockingxxwpm," there will be CW copy on your
computer screen. You shouldn't have to re-lock unless the station you're listening to changes
its CW sending speed.
Transmitting CW
The MFJ-1278B will transmit International Morse code from 5 to 99 WPM.
The CW transmitting speed defaults to 20 WPM. The MSPeed command specifies the CW
transmit speed. If the FARnswor command is ON, and MSPeed signifies 15 WPM, then the
MFJ-1278B uses 15 WPM characters, but spaces the characters so the transmitted text is at a
slower speed. To set the MFJ-1278B to 15 WPM, type:
MSPeed 15 <ENTER>
or
MODE CW,15 <ENTER>
Be sure the MFJ-1278B is in command mode when issuing the MSPeed or MODE
command.
The MFJ-1278B provides yet another way to set the CW transmit speed, and that is the
CWSPEEDM command. If the CWSPEEDM command is ON, then the MFJ-1278B will
match your transmit speed with the transmit of the person you are in QSO with. The CW
speed matching feature causes your MFJ-1278B to adopt the speed of the received CW signal
as it's transmit CW speed. This is the same CW speed that the MFJ-1278B analyzed last,
either through the AUTOTrac or by use of the ALOCKCHAR character, CONTROL-U.
To give the user with more flexibility in controlling how the MFJ-1278B will transmit
CW/MCW, the CWSEndch command is provided. This command applies whether the
keyboard or key paddle is the transmit medium. CWSEndch is only effective for CW and
MCW modes.
The CWSEndch command determines which keyboard character transmits the CW/MCW
characters. This gives the user more control how pending characters are transmitted. For
example, setting the CWSEndch to $02 will tell the MFJ-1278B to buffer all CW characters,
until the user enters a CTRL-B from the computer keyboard. Entering the CTRL-R
character will always transmit the buffer.
