Unified Microsystems SCI-6 Interface: FULLY ASSEMBLED, NOT A KIT!
Unified Microsystems SCI-6 PC Sound Card Interface will get you on PSK31, RTTY, WSJT, EchoLink, and other exciting digital modes by utilizing your PC's internal sound card.
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.
For convenience, the cables to your PC's sound card are included.
$15 + exact shipping.
