Introduction
The VEC-204 Electronic Keyer Paddle with Memory is an iambic keyer and
paddle combination. The VEC-204 is a microprocessor controlled keyer that
provides iambic key operations 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. You also get to
choose between Iambic Type "A" and Type "B" keying. It even has a non-
volatile memory to record and play a message of your choice.
Control Functions
1. The
Power button turns the unit ON and OFF. The power is ON when the
button is locked in the "in" position and the LED is lit and OFF in the "out"
position.
2. The Semi-Auto/Auto button allows semi-automatic "bug" and manual
operations. The keyer generates dots automatically. Dashes are manually
made. The keyer is completely manual when only the dash is used. Semi-
Auto is active when the switch is locked in the "in" position and Auto is
active in the "out" position.
3. The
Message button lets you record and play a message from the non-
volatile memory. It is a momentary time sensitive push-button.
4. The
Speed control, located on the left side of the unit, varies code speed
from 2 to 65 WPM. Turn the control clockwise to increase speed and
counter-clockwise to decrease speed.
5. The
Volume control, located on the left side of the unit, adjusts the sidetone
level of the internal speaker. Turn the control clockwise to increase the
volume and counter-clockwise to decrease the volume.
6. The
Weight control varies the code weight from approximately 10% to
190%, with the standard dot defined as 100% weight. The standard dot-
dash-space ratio is 1:3:1 (trimpot at mid-range). This control is accessed
through a small hole on the rear of the unit and may be adjusted using a
small flat-headed screwdriver. This control is turned clockwise to increase
dot and dash lengths and counter-clockwise to decrease dot and dash
lengths.
