The model DS Series homing beacon is a continuous wave transmitter with an adjustable output power of up to 25 watts, the power of a single carrier.

Optionally, a second carrier may be added to the first to prove modulation, producing a signal with an AM type waveform and a SSB bandwidth. The bandwidth of a dual carrier emission is the same as the audio tone (either 1020 Hz or 400 Hz).

The transmitter operates on 115/230 VAC 50/60 Hz or 48 VDC, optionally 24 or 12 VDC.

Optionally an automatic shutdown circuit is included that automatically shuts down the transmitter if power falls below and adjustable level, if the “ident” signal fails or if extreme distortion is present.

The transmitter is in a rain-tight enclosure that permits it to be mounted out-of-doors at the base of the antenna.
