Hi All,
A noob question, if I may.
I am (finally) cobbling some gear together to have a play with this FT8 business.
As the PC and the radio are powered from different sources, one of which is a switch mode power supply, I gather that it would be prudent to have some form of isolation between the radio and the sound card.
Would a pair of 1:1 transformers be enough? Or would optocouplers be a better solution?
