@MrKennnyj I did explain why this is the case in the video. Using the radio interface with transformers does compromise the low frequency response which does corrupt the data and makes the D-Star error correction work overtime to get everything back. D-Star does not sound like FM, there is a price to pay for only using 6.25KHz of bandwidth for audio instead of 20 or 25KHz. Personally I think this is a perfect example of "ham radio"...
Michael, thanks for the clarification that you're using an analog (9k6) radio for d-star. I was horrified at spending usd 500 for a radio just to use the network! My old passion for older hardware (as in I already own it) is justified!
I think I've got most of the parts needed to do this now, so I'll be able to talk to you one of these days without having to post on these videos.

Why does everybody sound like a computer generated voice not ham radio really,audio and sound quality is awful

hello Michael,
This is a great video. So far I have only been able to make a DSTAR simplex
contact with my IC-706MKIIG. My tx audio still has a lot of R2D2 problems. I am waiting on a new
USB sound that I hope will solve the problem. If not I will try another computer.

Thanks for taking time to "walk through" the build in details - yet another useful video!
