Unified Microsystems SCI-6 PC Sound Card Interface Kits

Unified Microsystems SCI-6 PC Sound Card Interface Kits are an affordable option to get you on PSK31, RTTY, WSJT, EchoLink, and other exciting digital modes by utilizing your PC's internal sound card. These SCI-6 interfaces are your ticket to cutting-edge digital communications developments.

Their design incorporates transformer isolation on both transmit and receive audio. The PTT circuit interfaces to a PC serial port through an opto-isolator to generate automatic transmit/receive control. Since the computer PTT-out pulls high, these SCI-6 interfaces require no external power source.

These SCI-6 kits also make a great club project! Give your members some kit-building experience, as well as an introduction to new modes. These kits contain a high-quality, double-sided circuit board with a solder mask and component legends for easy assembly. Unlike other low-cost kits, a machined case is included.

For convenience, the cables to your PC's sound card are included. You supply the cables to your particular model of radio. RCA phono connectors make it easy for you to customize the remainder of the connections to your radio. Software for many of the digital modes can be downloaded from the Internet at no cost.

When using a PC sound card for digital modes, you may inadvertently transmit sounds generated by your operating system. PC-based sounds can usually be eliminated by a settings change. Please see our images for an example of how to eliminate PC sounds.
