DSP-2232 Multi-Mode Digital Signal Processors

Top of the Line Controller

This is the Cadillac and the Corvette of data controllers rolled into one. Work satellites, HF, VHF, even Gateway between HF and VHF. The DSP-2232 with two simultaneous ports, provides a new level of performance and versatility in data controllers.

Built for the Future
The great advantage of having Digital Signal Processors in your data controller is that new modems or modes only require new software. Unlike an analog modem which usually requires that new hardware be installed. In addition, DSPs provide filtering that analog machines just can't match.

All Proven Modes
PACTOR, VHF/HF Packet, AMTOR/SITOR, Baudot, ASCII, Morse, TDM, and NAVTEX. As new modes become available, all you need are replacement EPROMs. Satellite and all the modems that made the PK-232MBX a legend are included, plus the K9NG and G3RUH compatible 9600 bps modems. For specific modems included, see below.

Full MailDrop
You get the latest version of MailDrop with selective control of third party traffic and bulletin board system (BBS) compatibility so messages can be automatically forwarded.

True Gateway & Dual Ports
The DSP-2232 has the ability to create a gateway from packet-to-AMTOR, packet to PACTOR, and of course, packet-to-packet. Since you have dual simultaneous radio ports, the DSP-2232 allows cross-mode gateway operation. Packet users connecting to Port 2 have the ability to monitor and link to other AMTOR, PACTOR, or even packet stations using your HF radio on Port 1. The dual ports also offer simultaneous HF and VHF monitoring, or running two VHF packet radios at the same time. You can also listen to your local DX node while working AMTOR on an HF frequency.

LCD Readout
The unique LCD read-out on the DSP-2232 displays the mode and diagnostics for both radio ports, giving you information on connect and system status. On packet, the LCD displays the call sign of stations heard. On RTTY, AMTOR, and PACTOR, text received on the air is displayed. This is true for both radio ports of the DSP-2232

TDM Capability
As with all AEA multi-mode data controllers, these DSPs will decode Time Division Multiplex (TDM) signals. TDM is a mode resembling FEC AMTOR used in commercial applications. TDM uses one sub-carrier, but assigns separate data channels to different time slots.

A Satellite Workhorse
The satellite modems included make the DSP-2232 the premier satellite data controller on the market. The automatic Doppler correction keeps the signals coming in clear. Up/down Doppler shift for PSK modems and outputs for up/down frequency stepping to control the radio's frequency included. The onboard 9600 bps modem lets you bounce packets off satellites and communicate with terrestrial stations at a blazing rate. With the optional AEA WeFax 256, receive real-time, true grayscale images from either NOAA HF WeFax Service or the NOAA APT Satellite Service. Take a look at the Satellite modems available to you and you will see how AEA has engineered the DSP-2232 and DSP-1232 to be the best tool for working the satellites.
