Most sound card interface designs include isolation between computer and radio signals using transformers for audio and optoisolators or solid state relays for PTT. If one wanted to have a sound card interface connected at the same time as the KIO2 or KPA100 serial control cable, the signal ground on the serial control cable is not isolated, and so would provides an unwanted ground path between the radio and the computer. Is there a way to isolate the receive data, transmit data and signal ground lines of the serial control cable such that this ground path is eliminated? I am looking for a homebrew solution as opposed to a pre-packaged approach, but I can't seem to find any info on the net besides pre-packaged.
