Note
The Trac TE-133 CMOS Electronic Keyer was made by Trac Electronics out of Buffalo, New York (later Charlottesville, Virginia).
It used CMOS integrated circuits, which offered high reliability and low power consumption compared to earlier TTL designs.
Specifications
– Circuitry: All-CMOS design, which allowed it to interface safely with a variety of rigs without the high current draw of older logic families.
– Keying Speed: Typically adjustable from 5 to 50 wpm.
– Keying Type: Supports Iambic keying with any squeeze paddle.
– Logic Features: Self-completing dots and dashes.
– Both dot and dash memories
– Weighting is fixed to maintain a 3:1 dash-to-dot ratio.
