The DSP-232
Overview
The DSP-232 was designed by Timewave Technology Inc. to be the ultimate digital operating platform
when coupled to your computer or “dumb” terminal. The DSP couples your HF, VHF, UHF transceiver(s) or short-
wave receiver to your computer so you can “talk” to other Amateurs or listen in to their—or a utility station’s—
digital and Morse communications. This unit is state-of-the-art and has been designed with an eye toward the future.
The architecture and parts used in the DSP-232 allow room for future technological enhancements.
Timewaves ’s PK-
232MBX left a decade long legacy of dependability and high-performance digital communication, the DSP-232 will
carry you through the next decade, and well into the next century.
Capabilities
With the DSP you can transmit and receive all the popular amateur digital modes. You can receive other modes
such as NAVTEX and bit-inverted Baudot RTTY. These capabilities, along with SIAM (Signal Identification and
Acquisition Mode), make the DSP ideal for the digital signal short-wave listeners (SWL) as well as the active
digital communication users. New modes will become popular and you can be assured this unit will be able to
handle them.
The DSP will transceive in the following modes:
♦
AX.25 packet on HF (300 bps), VHF and UHF (9600 bps and 1200 bps)
♦
Baudot and ASCII RTTY
♦
AMTOR/SITOR CCIR Rec. 476 and 625
♦
Morse Code
♦
PACTOR
In addition, the DSP receives the following modes:
♦
NAVTEX marine broadcasts and AMTEX amateur bulletins
♦
Bit-inverted Baudot RTTY
The DSP also has the following special features:
♦
Gateway firmware which allows the DSP-232 to operate as a node and identify TCP/IP, TheNet, and
NET/ROM stations. There are two heard lists with Gateway, one for nodes heard and one for stations heard.
♦
Memory ARQ for better HF throughput in marginal conditions.
