DTMF Generator for Vehicle

DTMF Generator for Vehicle

The device functions as a DTMF (Dual-Tone Multi-Frequency) encoder and modulator, integrating the generated codes into RF signals within standard communication radio frequency bands. It is capable of generating DTMF codes ranging from 1 to 4 digits and transmitting over the frequency ranges of 136–174 MHz, 245–247 MHz, and 400–520 MHz. The transmission range spans approximately 2 to 15 kilometers. This device is designed to transmit DTMF codes for remote detonation initiation, thereby enhancing operational safety for personnel in the field.
