It is known by a number of different trade names such as Private Line (PL) by Motorola, Channel Guard (CG) by General Electric and generically as tone squelch. Receivers for agency XYZ are set to only open their audio squelch when the proper sub-audible frequency tone is part of the transmission. Ctcss Decoder Board Code Letter ToThere is no generic standard tone number assignment or code letter to go with a particular tone; however, below is a chart of the commonly accepted 50 tones used at this time. On the internet I found an excellent description of a CTCSS generator which. The DDS itself runs at 3906.25 Hz. A 16 bit DDS is used giving a step of approximately. I also replaced the 18pin 16F628A with the smaller 14pin 16F684 microcontroller. The frequency is, even when the exact crystal frequency is not known, within. To add a CTCSS frequency the phase increment should be calculated: The DDS step is the crystal frequency divided by 226 (67108864). The latter will give a step of (400000067108864) 0.059604644775390625.
