HAL COMMUNICATION CORP. - CLOVER 2000 - DSP 4100 MODEM
 
The DSP4100 2K is an HF data modem that provides clover 2000, a 2000 bits/sec voice bandwidth, adaptive waveform specifically designed for HF radio data communications. clover 2000 measures real time hf signal conditions and sets the most efficient modulation for these conditions. 8 bit data is sent without extra manipulation or modification. ARQ mode is simultaneously bi directional duplex and does not require an over command. FSK waveforms cctr 476 / 625 tor, p-mode, baudot and asii are included. Housed in an rf tight shielded enclosure, the dsp modem operates on 10 to 18 volts dc. Internal modem software can be uploaded into the dsp 4100 2k into non volatile flash memory, greatly simplifying addition upgrades. The DSP4100 2K is particularly well suited for use with lap-top terminals pc's in a portable or field environment. Many third party software packages are available.
