Ctcss Decoder Board Tnxaser Description: the ct 30 is a ctcss decoder encoder on a single printed circuit board. upon decoding a valid ctcss tone, the board gives a logic change. both active high and low outputs are available simultaneously. a mx 465 (fx 465) ctcss chip is used for ctcss detection. Decodes 16 different pairs of tones. pin dv (data valid) enables a demultiplexer. max current on each output of 74ls154 is 20ma. maximum af input is 1,2vss on c3. resistor r at the input is dependent on input voltage ( see table). pin toe is useful to enable three sate output of mt8870.

A ctcss decoder is used with a vhf or uhf receiver to detect a specific ctcss tone. when detected, the receiver audio is unmuted and the incoming signal can be heard. Comspec has become in business for over 35 yrs providing ctcss and some other signaling solutions for the land mobile phone (public security, govt, army) and novice radio services.

With the incorporation of the on chip tx and rx speech filter, the fx465 enhances voice tone multiplexing by attenuating tx and rx speech 36db at frequencies below 250hz while passing signals > 300hz with only 1db of ripple. The fx335 is a cmos ctcss encoder decoder used for the generation and detection of 38 sub audible tones. the sub audible tone encode decode functions are all derived from an on chip crystal oscillator and are digitally programmed by six wire link inputs. Continuous tone coded squelch system ctcss, also known as private line pl at motorola, tone lock at pye, and sub audible tone is a system used to reduce the problems associated with co channel interference. The model nc112 is a field tunable ctcss encoder decoder designed as a single p.c. board for direct plug in compatibility with relm’s repeater models; u 10r, wh 100r, wu 451r and earlier models u 10 and u 14 series repeaters.
