• PC to RTX interface - Schematics for IC-706, IC-718, IC-756PRO, TS-570, TS-870, and simple universal S.B. interface All three interfaces presented on this page employ galvanic isolation of the transceiver from PC computer. Audio paths are separated by transformers, optocouplers serve to separate the digital paths (PTT and RTTY keying).

• CW Decoder  ^pop - This program allows CW operators to copy CW code with a computer. The decoded CW is displayed as text or can generate a side tone. There is a spectrum display of the audio with a sliding cursor to select a particular audio for decoding. The program also allows for keying a transmitter from the keyboard with full CW break-in operation.
