To insert a steady carrier, use the 

/C

n

 command, where 

n

 is the number of seconds (from 1 to 9) 

that you wish to send the carrier. 

QSO Number:

 The keyer will send the current QSO number.  You can use the paddles to set the QSO 

number anywhere from 1 to 255.  Note that when the QSO number is auto-incrementing, it can go from 
1 to 65535.  To reset the QSO number to 1, simply tap both paddles at the same time. 

RL 

(Default: 5 

WPM) 

Range Low:

  This sets the low end of the speed control pot range.  The setting is adjusted the same way 

you would set the stored speed – the dot paddle will reduce the setting, the dash paddle will increase it. 

RH 

(Default: 

40 WPM) 

Range High:

 This sets the high end of the speed control pot range.  Set the same way as the stored 

speed and low range setting.

 

(Default: 

OFF) 

Auto letter spacing: 

The keyer will announce the current setting and wait for input.  Automatic letter 

spacing takes effect for messages sent from memory as well as code sent manually with the paddle. 

 

0 turns automatic letter spacing off.  In this mode you control the spacing between letters.  This 
is the default setting, and is the same as most keyers.

 

 

1 turns on auto letter spacing at the set speed.  A letter space is automatically inserted if the 
keyer detects no input from either paddle at the end of the space after a dot or dash.

 

 

Settings from 2 to 9 will set automatic letter spacing with longer delays.  For example, selecting 
2 will insert one extra “dot” length spacing between characters.  Selecting 3 will insert an extra 
2 “dot” lengths, and so on.  

 

 

Note that auto letter spacing is ignored while in setup mode.

 

(Default: 

0/9) 

Cut numbers:

 The keyer will send 

Ø

 and 

9

 using the current setting and wait.  You can cycle between 

no cut numbers (

Ø 9

) cut zeros (

T 9

), cut nines (

Ø N

), or both (

T N

).  Note that this 

only

 affects the 

way QSO numbers are sent.  Other numbers in stored messages, or numbers sent by hand, are not 
affected.  The default setting is no cut numbers. 

(Default: 

N) 

Leading Zeros: 

The keyer will send “Y” or “N” and wait.  As with other menu settings, either paddle 

may be used to switch between the two settings.  

Y

 will send numbers in stored messages with up to 

two leading zeros (1 is sent as 001, 99 is sent as 099, 123 is sent as 123, 1000 is sent as 1000).  

N

 sends 

numbers without leading zeros.  Like the X setting, this affects only QSO numbers and not other 
numbers stored in messages or sent manually.  The default setting is N. 

B  

(Default: 

15 sec.) 

Beacon delay:

  The keyer sends the current beacon delay in seconds.  Use the dash paddle to increase 

or the dot paddle to decrease the delay between beacon transmissions from 0 to 99 seconds.   

(Default: 

5) 

Weight

:  The keyer announces the current weight and waits for input.  The dot paddle may be used to 

decrease the weight or the dash paddle to increase it.  Weight can be set anywhere from 1 (50% "light") 
to 5 (normal) to 9 (50% "heavy").  The default setting is 5. 

(Default: 

Y) 

 

Sidetone

:  The keyer announces the current sidetone setting and waits for input.  You can use the dot 

and dash paddles to switch between “N” (sidetone OFF), “Y” (sidetone ON) and “M” (MCW mode).  
In MCW mode, the keying output is active any time code is being sent and for two word spaces after 
the key is released.  This can be used to control the PTT line of an FM transmitter.  Regardless of the 
sidetone setting, the sidetone is always used while in setup mode. 

(Default: 
Mode A) 

Key Mode:

 The keyer will send the current keying mode: "

A

" or "

B

" for iambic A or B timing modes, 

U

” for Ultimatic, “

G

” for bug or “

S

” for straight key.  You can use the key or paddle to switch 

between modes.  In “Bug” mode, dots are made automatically with the correct spacing and length with 
one paddle input, while dashes are made manually with the other.  If straight key mode is selected while 
using a paddle, either paddle input will key the transmitter.
