MFJ-1278B MULTI-MODE BASIC OPERATION
Tuning your Radio
The MFJ-1278B lets you tune your radio with the TUNE command. The TUNE command is
issued from the command mode. The user can use the TUNE command in any of the MFJ-
1278B operating modes.
The TUNE command activates the PTT line for 30 seconds. After 30 seconds MFJ-1278B
will automatically return to command mode. To abort tuning before 30 seconds, press any
key on the keyboard.

Random Code Generator
If you want to improve your CW copying proficiency, you will find the CW Random Code
Generator helpful.
The RANDOMCW command invokes the Random Code Generator. Setting the
RANDOMCW command to ON, activates the Random Code Generator. The Random Code
Generator can generate Pseudo Ransom Code in two formats. The two formats of Pseudo
Random Code are NORMAL CW and FARNSWORTH CW. The MFJ-1278B uses the
setting of the FARnswor command to determine which format to send when RANDOMCW
is ON. To end CW random code generation, type:

RANDOMCW OFF <ENTER>
CW random code speed is set by using the MSPEED command described above.
Many find training for CW tests with a FARNSWORTH method of code generation more
valuable. It teaches letter recognition at a speed fast enough to avoid the common learning
"plateau." The learning "plateau" proves to be difficult for some people to get over. This is
because as their code speed increases, they must re-learn the sound of the characters.
To select the Farnsworth method of random code generation, set the FARNSWOR command
to ON before entering the RANDOMCW mode.
When the FARNSWOR command is ON, the MFJ-1278B generates random code using
standard 15 word-per-minute timing for all code elements. When using the Farnsworth
generation method, the inter-character spacing is increased to send the text at the slower
selected speed. So with the FARNSWOR command ON, the code generator sends the CW
characters faster, but slows the text down to a slower speed. The FARNSWOR command
controls the transmission of CW characters, whether the computer keyboard or key paddles
are used.
