Universal M-200F

The Info-Tech M-200F receives Morse code with autorange from 5 to 105 WPM. It also decodes regular Baudot radioteletype still used by some international press agencies, weather stations and aeronautical concerns (45, 50, 57, 74 and 100 baud). Modes and speeds are easily selected by the function knob Threee standard shifts of 170, 425 and 850 Hz can be selected, plus variable shift. It also decodes ASCII at 110 baud. The Morse code demodulator is centered on 1000 Hz, but is adjustable. The ATC - Automatic Threshold Control feature allows RTTY decoding with reception of either Mark or Space. This is useful during marginal or fading conditions. The UOS - Unshift on Space function is useful when copying RTTY text (resets to LTRS case upon receipt of the SPACE character). A Wide-Narrow switch alters the bandwith of the RTTY demodulator. LED indicators include: Mark [MK], Space [SP], Auto-start, Morse lock, Buffer Overflow, Limiter and Bar graph tuning.
