Electronic CW Keyer

Introduction

The CK-200 Electronic CW Keyer is a microprocessor controlled keyer that
provides iambic key operation and dot-and-dash memory to make sending
perfect code easier. It has tunable code speed, code weight, and sidetone
frequency; it supports both direct and grid-block keying outputs as well as relay
contact output. You also get to choose between type A and type B iambic
keying.

Control Functions

Figure 1. CK-200 Front Panel.


1. The

On/Off button turns the unit ON and OFF. The LED lights when the

unit is ON.


2. The

Iambic button selects type A or type B iambic keying. When a

squeeze is released during an element (dot or dash), type B adds the
opposite element. Type A just finishes the element in progress and does not
produce a following alternate element. For example, in type A iambic, a
squeeze release during the "dah" in the letter A will produce "di- dah" (A).
In type B iambic, a squeeze release during the "dah" in the letter A will
produce "di-dah-dit" (R).


3. The

Tune button continuously keys the transmitter for tuning.


4. The

Speed control varies the code speed. The speed range is configured

with an internal jumper (JMP1) for 5 to 65 WPM or 10 to 40 WPM. Turn
the control clockwise to increase speed and counter-clockwise to decrease
speed. The unit is factory set to 5 to 65 WPM with JMP1 at the "L"
position. To make the speed adjustment less sensitive, change the speed
range to the narrower range of 10 to 40 WPM. To change the speed range,
