MFJ-422E/422EX Instruction Manual 

Electronic Keyer Paddle 

Introduction 

 
The MFJ-422E 

Electronic Keyer Paddle with Memory

 is an iambic keyer and 

paddle combination.  The MFJ-422EX keyer installs on your MFJ-564 or 
Bencher type paddle.  Both are microprocessor controlled keyers that provide 
iambic key operation and dot-and-dash memory to make sending perfect code 
easier.  It has tunable code speed, code weight, and sidetone frequency; it 
supports both direct and grid-block keying outputs.  You also get to choose 
between Iambic Type "A" and Type "B" keying.  It even has a non-volatile 
memory to record and play a message of your choice.

otherwise stated. 

 

Control Functions 

 
1.

 

The 

Power

 button turns the unit ON and OFF.  The power is ON when the 

button is locked in the "in" position and the LED is lit and OFF in the "out" 
position. 

 
2.

 

The 

Semi-Auto/Auto 

button allows semi-automatic "bug" and manual 

operations.  The keyer generates dots automatically when a squeeze or 
single lever key is used.  Dashes are manually made.  The keyer is 
completely manual when a straight key is used.  Semi-Auto is active when 
the switch is in the "in" position and Auto when in the "out" position. 

 
3. The 

Message

 button lets you record and play a message from the non-

volatile memory.  It is a momentary push-button that is time sensitive. 

 
4.

 

The 

Speed

 control, located on the left side of the unit, varies the code 

speed.  The speed range is configured with an internal jumper (JMP9) for 5 
to 65 WPM or 10 to 40 WPM.  Turn the control clockwise to increase 
speed and counter-clockwise to decrease speed.  The unit is factory set to 5 
to 65 WPM.  To make the speed adjustment less sensitive, change the speed 
range to the narrower range of 10 to 40 WPM.  To change the speed range 
the power must be off, then remove the paddle to access the jumper inside 
the case.  Locate jumper JMP9 next to the microprocessor and set it to the 
"H" position. 

 

Note:  Power must be off when changing the jumper settings.
