Function Commands

Commands to the keyer are entered in Morse code using your paddle. The keyer disables output keying. When the function is complete, output keying is enabled, and the previous operating speed is restored.

1 Press [CH 1]+[CH 2].

¥The keyer will send ÒFÓ.

2Send a Function command from the table.

¥ If an incorrect command is input, a multi-dit error tone will be sent.

Function

Command Name

Description

Command

 

 

A

Auto-space

Toggles the automatic character spacing feature ON or OFF. The keyer confirms

 

 

the new state by sending "ON" or "OFF". Auto-spacing helps form properly

 

 

spaced characters within a word. Character crowding is prevented by forcing at

 

 

least 3 space elements whenever more than one space is detected. This effect is

 

 

especially noticeable at low speeds. Without auto-spacing, character spaces are

 

 

determined by the operator.

D

Decrement

Decrements the serial number by 1, effectively canceling the automatic increment

 

 

applied when last played from a message. The decrement function

 

 

accommodates re-sending the last serial number, as might be needed when a

 

 

repeat of a contest exchange is requested.

 

 

 

F dd

Function speed

Sets the speed used for function entry to dd wpm, where dd are two digits in the

 

 

range 06 ~ 30. This speed is used to enter commands and load messages. It is

 

 

independent of operating speed and is unaffected by the analog speed control.

 

 

Alternatively, "dd=00" makes the function speed track the operating speed.

 

 

 

H

Hand-key

Causes the keyer to enter the Hand-key mode. Keying output will follow closures

 

 

of the dot and dash paddle levers, allowing hand-sent code. Normal iambic keyer

 

 

operation is regained by any button closures.

K dd

Keying

Increases keying on-time and decreases keying off-time by dd milliseconds,

 

Compensation

where dd are two digits in the range 00 ~ 25. Although similar to increasing

 

 

weight, this adjustment is independent of speed. This setting is used primarily to

 

 

correct keying distortion introduced by the transceiver using Break-in operation.

 

 

 

L

Load mode

Toggles the load mode between Character and Real Time. The keyer confirms

 

 

the new mode by sending "C" or "R" as appropriate.

 

 

 

N dddd

Number

Initializes the contest serial number to dddd, where dddd are four digits in the

 

 

range 0000 ~ 9999. Four digits must be entered (with leading zeros if needed).

Q

Queue

Toggles the input queue ON or OFF. The keyer confirms the new mode by

 

 

sending "ON" or "OFF" as appropriate. When OFF, message button activations

 

 

are acted upon immediately, canceling any message in progress. When ON, up

 

 

to eight button presses are remembered in order and acted upon in succession as

 

 

each message completes.

RV

Reverse

Reverses the dot and dash paddles as may be desired for left-handed operators.

 

 

 

S dd

Speed

Sets the current operating speed to dd wpm, where dd are two digits in the range

 

 

06 ~ 60. The speed function establishes the current knob position at the entered

 

 

speed. The knob can then be employed to vary the speed faster or slower over a

 

 

total range of 3:1. Control via the knob is linear and increases speed clockwise.

 

 

 

SU d

Speed Up

Increases the operating speed by d wpm. d is a single digit in the range 0 ~ 9.

 

 

 

SD d

Slow Down

Decreases the operating speed by d wpm. d is a single digit in the range 0 ~ 9.

 

 

 

V d

Emulation

Allows an operator to select emulation of the timing characteristics of other keyers.

 

 

 

W dd

Weight

Sets code weight to dd percent, where dd are two digits in the range 25 ~ 75.

 

 

Weight is the duty cycle of a continuous string of dots, which is 50% for perfect

 

 

code. A higher weight produces a heavier sound, and a lower weight causes

 

 

characters to sound lighter. Once set, weight remains constant and independent

 

 

of speed.

 

 

 

X

Xmit (tune)

Continuously keys the output for purposes of transmitter and amplifier adjustment.

 

 

Tuning is stopped by simply tapping either the dot or dash paddle.

 

 

 

Z d

Zeros and

Controls the way that zeros and nines are sent in the serial number. See "Serial

 

Nines

Number Options".
