- | ====== Single Paddle Electronic Keyer Model 670 ====== | ||
- | {{670.jpg?150|}} | ||
- | ===== 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). | ||
