Local Generator Unit

External Generator for Collins KMW-2(A) & S-Line

The DDS-2A is a microprocessor controlled external VFO for the Collins KWM-2(A) and S-line, including 75S-3 and 32S-3. The DDS-2A uses the latest DDS and PLL technology to produce accurate and clean local signals for the equipment. The unit utilizes an original BFO of 435.65kHz(456.35kHz) in the Collins equipment.

The DDS-2A replaces PTO and HFO in the equipment. You can expect 10 Hz frequency resolution and accuracy in the transmit and the receive.

Because of the clean local injection, you can expect performance improvement, including inter-modulation and cross-modulation characteristic.
