Could we provide a 10 meter repeater with a delay line,
so you could hear your own audio before the contest?

It would seem the use of computer sound cards as voice keyers is the root cause of most SSB modulation and clarity issues. It took me several sound cards before I found a combination that sounded good.
We have several choices as a community. We can simply not work guys with bad audio. Or we can work them and then tell them their audio is bad.
Perhaps if enough people said something, they would work on it.
