Code Practice Oscillator WIRED OCM-2W - $29.95

Thousands of Morse students have started with a key like this, going back to the 1920's.  Perfectly adequate for sending practice, and an inexpensive gift for that child who might be interested in learing code.  Spring tension and contact spacing are adjustable.

This is the famous "Japan ball bearing key," which has been in continuous production since the 1950s.  It has a brass-plated base, silver contacts, a shorting switch, and adjustable ball bearing trunion for smooth and reliable operation under a wide range of circumstances.  Contact spacing and spring tension are easily adjusted and the binding posts are "three-way" to support multiple connection methods.   

Brass Key AM-K4 - $19.95

Need a base for your new AMECO K-4 key?  Our new universal key base is a perfect match. It's a black crinkle-finish aluminum plate with four cushioned feet, tapped #8 screw holes to match the K4 (and many other keys with 2-1/2" hole spacing), and two brass screws with tapered heads so they won't interfere with the switch. The key must be ordered separately, but it is a 2 minute job to install it on the base.  Made with pride in the USA.
