Morse ID Timer / Annunciator
The ID-O-Matic II kit uses a microprocessor based, single chip ID timer/annunciator intended for Amateur
Radio and other applications. Several modes of operation make it suitable for use in the shack or as an
automatic Morse code ID for beacons, repeaters and “fox hunt” transmitters. The ID-O-Matic II includes
audio mixing, de-emphasis and amplification as well as input signal conditioning and output drivers.
