Description

NOTE This item is held on reserve for the buyer of the Century 21 Transceivers I have listed.

 

This Ten-Tec 670 Century 21 Electronic Keyer, is in Very Good Condition.

This one has been tested with a Century 21 and it is working great.

 It simply plugs in the back or the 570 and 574 (Digital) Century 21.

 This unit is part of a huge Ten-Tec collection which is being sold due the a planned move.

It is being sold as is, as described for a freind who has been collecting only the finest vintage gear.

Description

Designed specifically for use with the Ten-Tec Century/21 Transceiver. Features self-completing dits and dahs, preset weighting for optimum articulation in the most used speed range, speed control with a range between 6 and 50 words per minute, and an enclosure that matches the transceiver. Powered by the Century/21 power supply, no separate on-off switch is needed for the keyer. Incorporates low voltage positive transistor switching to interface with the Century/21 keying circuit (it will not key transmitters with cathode or grid-block keying).
