Just found this link to a homebrew USB interface for digital modes. This is just the ticket for helping me build my shack. I am using a modern laptop with only 1 serial port and I want to save that for my FT-847 CAT port. I also can’t see paying $99 for a commercial interface.
I have build a lot of soldered kits over the years, but at some point I want to learn proper circuit board creation techniques. This is a pretty simple circuit so I should be able to use this opportunity to learn how to do proper circuit prototyping.

I just ordered 4 (!) of the sound cards referred to in the article off of eBay. Total cost with shipping? Less than USD $8.
Great work G4ILO!
