Receiver Exciter is used to receive and transmit HF range signals & processing HF signals into voice and data format using DSP technology. It consists of high quality HF receiver and HF exciter. System has SELCAL and secure communication features. System has configuration facility for Frequency range, mode of operation (AM, LSB, USB, DATA, CW), volume, squelch level from external control unit. The exciter produces the low power signal which is fed to the power amplifier unit.
