About This Product
This modem carries data over an HF radio link using a selective repeat protocol at 2400 bps with 16-channel QPSK modulation, and sets up links with a proprietary 80 baud CHIRP mode. Built-in compression lifts the transfer rate to up to 6000 bps, against up to 1475 bps uncompressed. It links to the transceiver over a 9600 baud RS-232 interface, runs from 13.5V DC nominal within a 9-16V DC range, and works from 0°C to 55°C.
