The model FLEX IIIA is a high quality low cost CTCSS, DCS and LTR Controller supporting 51 CTCSS tones, 112 DCS codes, and 250 LTR codes per panel. This product was first introduced in 2006 and was our first controller to support all three formats at low cost.

Programming the computer is by means of a Windows based program running under Window XP Service Pack 2 or Vista.

Up two two of the controllers can fit in a single 1U rack mount chassis. Removable Screw type of terminal block on the back allows easy hookup to any repeater. The connector is compatible with our LT4200 Controller in both form and pin outs.

Programming is via a Windows based computer or remotely over the air using the DTMF keypad of the radio.
