[App_rpt-users] duplex=2, hear myself, repeater

I think I understand what he's saying. It's just the usual latency combined with a really fast TR turnaround on his radio (not the repeater but whatever he's accessing the repeater with). If you listen to the output of your repeater while you're transmitting, you'll notice a bit of a delay. No way around that, I'm afraid, but that's what you're hearing.
