The Broadcast Techniques Model 1 is a DSP driven multimode AM exciter for use as a low power broadcast quality exciter. This system is capable of driving your high power amplifier in ISBFC, ISBSC, DSBFC, DSBSC, SSBFC, and SSBSC with Hi-Fidelity quality in monaural or AM Stereo modes. Units can be customized to individual specification. Direct Digital Synthesis (DDS) is used in units supplied with internal frequency generation requirements which permits the versatility of direct output at the transmitting or I.F. frequency. DDS models are capable of tuning from 50 KHz through 30 MHz.
