Featured Items

Typical box style unit, assembled from kit.

AMECO, the first code practice device I met.

Typical key buzzer from Japan. I have over a dozen variants.

I never saw these older key buzzers as a kid, but there must have been a lot made.

Another classic kit from Heath, during the "Benton Harbor S-Line" era.

A beautiful kit from Knight.

A classic tube unit, this one owned by an SK friend, K4BXJ.

A mass produced but quality item from Johnson.

A modern set still on the market from MFJ.

This is a quality device from NYE with a good Speed-X key and weighted base.

Comprehensive station keyer with code practice built in. I still use one.

These were ubiquitous in my early years. Many were licensed via one.

A representative Instructograph of the later period.

A classic MAC key/buzzer, my most expensive collectable.

ATKO used by FCC for exams, including my 13 and 20 wpm in the late 60's.

From England, a random code generator that speaks!

Complete training package from Hallicrafters, including HA18/A CPO, key, books, and LP record
