About Setup Mode 

In setup mode, all except the U, M, V and F commands share a common method of reviewing and changing the 
current setting.  In general: 

 

Send the letter corresponding to the setting you want (M, S, etc).  In “Button” command mode, hold the 
button until you hear the letter of the item you want to review or change, then release it. 

 

The keyer will respond with the current setting. 

 

For most commands, simply use the dot or dash paddle to change the setting.  Tapping either paddle will 
step through the possible settings.  The dash paddle “steps up”, the dot paddle “steps down”. 

 

Tap the setup button to return to the “?” command prompt (“Paddle” command mode).  In “Button” 
command mode, a short tap of the button will exit setup mode, while holding it will advance to the next 
setting. 

There are some exceptions to this rule.  The specifics for the U, M, V and F commands are detailed below. 

PicoKeyer Setup Menu Commands

  

Tune

 mode: Tune mode is used to send either a steady carrier or a series of dots for adjusting or testing 

your station equipment.  While in tune mode, each paddle acts as an on/off toggle switch.  Tap the dash 
paddle to turn a steady carrier on or off.  Tap the dot paddle to start or stop a continuous stream of dots.  
This is gives you a 50% duty cycle signal that is preferred by some operators as a way to tune up with 
less stress on final PA, tuner and antenna components. 

 

(Default: 

13 WPM) 

Speed

:  The keyer will always announce the 

current speed

 in WPM.  If the 

current

 speed is not the 

same as the 

stored

 speed, the keyer will announce the current speed followed by a slash and the stored 

speed.  For example: Assume the stored speed is 13 WPM, any you have the optional speed pot 
installed and set for 20 WPM.  The keyer will announce “20/13”.  If you have the pot set to its 
minimum, you will be using the stored speed and the keyer will only announce the stored speed, since it 
is the same as the current speed.  It sounds more complicated than it is; play with it a little and you’ll 
get the hang of it. 
 
You can adjust the 

stored speed

 from the menu.  Tapping the dot paddle will decrease the speed by one 

WPM, or the dash paddle will increase it.  Holding either paddle will continuously increase or decrease 
the speed, with a dot or dash sent at the new speed for each step.  When the paddle is released, the keyer 
will again announce the current speed setting and the stored speed, if it is different from the current 
speed.  Speed may be set from 5 to 60 WPM.  

Messages

:  Four message memories are available, numbered 1 through 4.  When you enter Message 

mode, message 1 will be the default selection.  You have a choice of actions available to you when in 
memory mode, selected by sending a single character from your paddle: 

 

Send the number 1, 2, 3 or 4 to select a message memory.  The keyer will respond by sending 

1

2

3

 or 

4

 to confirm. 

 

Send 

P

 (

P

lay) to listen to the contents of the currently selected memory.  The keyer will play 

the message, followed by the Morse prosign 

AR

 and the message number. 

 

Send 

R

 (

R

ecord) to record a new message.  If a message already exists it will be erased and 

replaced.  The keyer will respond with 

K

 to let you know it is in record mode.  Enter your 

message, with exaggerated word space but normal spacing between characters.  If you make a 
mistake when recording the message, just send 8 dots and the keyer will backspace one word.  
You will hear a single dot to confirm this (two dots means you are at the beginning of the 
message).  Tap the setup button once when you are finished recording.  The keyer will send 

R

 

and the message number to indicate the end of the message.  You can then 

P

lay the message 

back.
