I’ve heard a lot of people sing the praises of C4FM’s audio quality, but I don’t hear it. It’s clear, sure, but it’s also warblely and sounds like a robot trying to impersonate a person’s voice. Like the old Macintosh text to speech program from the 90’s.
I’m on a Wires-X net right now and some hams I know are checking in, I can kinda recognize their voice but takes me a minute.
