Yaesu FTS-8 CTCSS replacement module, working only as an encoder – intended for use with repeaters. Can be used with 9V or 5V PTT signal transceivers – see the build section for details.

Code created to implement a CTCSS tone encoder board into a amateur Yaesu radio Code was created to run on a PIC16 chip A tone encoder boards toargets to create a low frequency sin wave that access to ...

Short-range-radio co-existence is now possible using CTCSS carrier generation with a 256-B sine-wave lookup table. To allow multiple users to share one carrier frequency, many handheld transceivers ...

The AK2345 is an IC which supports CTCSS (Continuous Tone Controlled Squelch System), compatible with TIA/EIA-603 standard. A single CTCSS may be selected from among 50 different frequencies within a ...
