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 ...
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 project is an open source GNU repeater controller that is built around the Atmel ATMega1281 microcontroller while using all SMD components. Along with the microcontroller are the picoOS RTOS and ...
