Kenwood TS-870S instruction manual Function Commands, Communicating, Command Name

6COMMUNICATING

■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".
