Embedded Functions

Certain functions can be embedded within character messages. The command strings are prefixed by a Ò/Ó, and are entered as a separate word. The letters following a Ò/Ó that are contained within a word are not interpreted as an embedded function. For example, the keyer understands that ÒWD6DJY/VE7Ó does not include an embedded command since Ò/VE7Ó is not sent as a separate word. These commands must be stored in CH 1 ~ CH 4; they cannot be manually sent.

Com-

Command

Description

mand

Name

 

/B

Break

Message play pauses for manual

 

 

text insertion. One or more

 

 

words may be inserted via the

 

 

paddle. Once paddle input has

 

 

begun, the break is canceled

 

 

when inactivity exceeding a word

 

 

space is detected, and the

 

 

interrupted message resumes.

 

 

A break may also be aborted by

 

 

pressing any button, causing the

 

 

corresponding message to play

 

 

immediately.

/D

Decre-

Decrements contest serial

 

ment

number by 1.

/Gd

Gap

The normal 7-element interword

 

 

space is modified to 3+d, where

 

 

d is a digit in the range 0 ~ 9. It

 

 

is used to exaggerate inter-

 

 

character or interword spacing.

 

 

For example, a call like WØEJ

 

 

can be entered with slight

 

 

lengthening of the space

 

 

between the "E" and the "J" for

 

 

emphasis, making it easier to

 

 

copy. Note that /G0 yields a

 

 

normal character space, while

 

 

/G4 yields a normal word space.

 

 

 

/N

Number

The current value of a contest

 

 

serial number is played. Its

 

 

value is then automatically

 

 

increased by 1. See "Serial

 

 

Number Options".

 

 

 

/Pdd

Pause

A speed-independent pause of

 

 

d.d seconds is inserted, where

 

 

dd are two digits in the range 00

 

 

~ 99. For example, /P35 will

 

 

result in a delay of 3.5 seconds.

 

 

Pauses longer than 9.9 seconds

 

 

are obtained by using

 

 

consecutive commands that total

 

 

the value desired.

 

 

 

/R

Resume

Stops playback to allow hand-

 

 

sent entry. When manual keying

 

 

is completed, press the button

 

 

for the message being played

 

 

and the message will resume

 

 

transmitting. Multiple "/R"

 

 

commands are permitted.

/Sdd

Speed

The operating speed is set to

 

 

dd wpm, where dd are two

 

 

digits in the range 6 ~ 60.

/SUd

Speed

Increases the operating speed

 

Up

by d wpm, where d is a single

 

 

digit in the range 0 ~ 9.

/SDd

Slow

Decreases the operating

 

Down

speed by d wpm, where d is a

 

 

single digit in the range 0 ~ 9.

/Udd

Ultra-

Sets the ultra-speed mode for

 

speed

a message. Range is 70 ~

 

 

990 words per minute, where

 

 

dd are two digits representing

 

 

the first two numbers of the

 

 

speed setting desired. For

 

 

example, "07" is 70 wpm, "77"

 

 

is 770 wpm. This command is

 

 

used primarily for meteor

 

 

scatter work. Note that

 

 

Weighting (W) and

 

 

Compensation (K) settings are

 

 

disabled during Ultraspeed

 

 

message transmission.

/1,

Message

Message #1 is played followed

/2,

#1,

by resumption of the current

/3,

#2,

message. If the current

or

#3,

message is #1, a continuous

/4

or

loop is created. The same is

 

#4

true for the other messages.

 

 

 

Note: You can play back a message to listen to the Embedded function by simply pressing [CH 1], or [CH 2], or [CH 3], or [CH 4] for the channel that contains the Embedded function.

Serial Number Options

The ÒZdÓ command selects 1 of 10 options for sending zeros and nines in a contest serial number. Zeros may be replaced by ÒOÓ or ÒTÓ, nines replaced by ÒNÓ, and leading zeros suppressed.
