The Atronics code reader is a compact, solid-state instrument that decodes Morse directly from your speaker and displays the resultant message in alpha-numberic form on the front panel. A choice of readout size is available.
The model CR-101 characters are 0.65 inch high by 0.42 inch wide (16.5 by 10.7 mm); model CR-1O1A characters are 0.2 inch high by 0.15 inch wide (5 by 3.8mm).
All characters, including punctuation, are displayed one at a time. Code speed, on-off, and audio level are set by front-panel controls. The speed control, with settings between 0-10, is used as an indicator only. For any setting, code speeds between 70-140 percent of that setting can be decoded. For example, if the code reader is set for 14 wpm, it will display any code speed between 10-20 WPM.
An LED above the speed control indicates the expected length of a received dot. Another LED above the level control indicates mark (on) and space (off). The only connection required is a line between a phone jack on the code reader rear apron and your receiver speaker terminals. Input impedance of the code reader is 1000 ohms.
A RTTY interface module (model TU-102) is available as an optional accessory. The TU-102 accepts 5 level code (start, five data bits, two stop bits). Teletype speed can be selected for 60, 75, or 100 wpm. Auto features CR, LF, FIG and letters are provided automatically.
