Hi, I've been experimenting with various audio interface(s) from my radio to my sound card. Some suggest using 8 ohm transformers and some suggest using 600 ohm transformer. I'm confused as to why would they suggest using a 600 ohm transformer. The audio output from radios are 8 ohm. The audio output from sound cards are also 8 ohms. Why would I use a 600 ohm transformer?
Right now I built the interface by KD5ZUG with 600 ohm transformer and it seems to be working correctly, but I'm wondering if it could be better. Any assistance would be greatly appreciated. --73 de Doug (N1OBU Grid FN31XJ)
