An adaptable hybrid, implemented with digital signal processing (DSP), provides continually recalculated isolation between the off air HF signal and the telephone user, producing a reliable VOX signal (Voice Operated Xmit (transmit)) to key the transmitter when the telephone subscriber’s voice is present.
FULL AND HALF DUPLEX OPERATION
Designed for full-duplex, half-duplex, or simplex operation.
COMPACT DESKTOP PACKAGE
The compact desktop package has a built-in speaker with volume control to monitor call progress.
OPERATION WITH OEM TRANSCEIVERS
The 2061 is packaged in a 2000 series enclosure and is designed for direct interface via our standard bus cable to the Barrett 2050 transceiver. It can however be interfaced to other suitable HF transceivers.
