Transmitted Audio Quality: If you are a serious SSB operator like I am then you will pay close attention to the transmitted audo quality of your signal. Two black boxes that you basically use for HiFi SSB are the 8 Band EQ and the EQplus produced by Julius Jones, W2IHY. I have found that these two gadgets produce a transmitted audio that is as close as broadcast audio quality as I can get on SSB and Julius did a great job. I get consistently excellent reports on my transmitted audio quality and have also found that with signals that I receive and find with exceptional audio quality that the station on the other side is running the same pair of black boxes.
