Greatly Improve your RTTY copying capabilities. Adda crosshair LED Tuning indicator that makes tuning quick, easy with pin-point accuracy. Add mark and space outputs for scope tuning. Add LEOs that indicate 170, 425, 850 Hz shifts, Great for copying RTTY outside ham bands. Add sharp mark and space inters to improve copy under crowded/weak conditions. 170, 425, 850 Hz shifts. Add Normal/Reverse switch to check for inverted RTTY without retuning. Add output level control to adjust signal into your terminal unit. Add a limiter to even out signal variation for smoother copy. Unit plugs between your tuner and receiver. Mark is 2125 Hzr space is 2295, 2550 or 2975 Hz. Measures 10x2x6 In. and uses floating 18 VDC or 110 VAC with AC adapter, Mf\M312, $9.95.
