TONO Θ-350 - TONO THETA 350

THETA 350 RX TERM. This compact receive-only communications terminal is designed to demodulate and display the three most popular over-the-air modes of data communications: CW (Morse code), RTTY (Baudot), and ASCII.

• Any standard TV monitor can be used.
• A full-featured microprocessor controlled unit, the Tono Theta 350 has selective calling, battery backed-up memory, audio monitor, and informative L.E.D. tuning indicators . There is also interfacing to permit the addition of a dot matrix printer for "hard" copy and a keyer paddle input to permit CW transmission with full iambic operation.
• This unit is ideal for shortwave listeners and hams who have been missing the increasing volume of data communications over the air.
