VarAC - No conn on CQ and on conn attempts

New to this but it all appears to be setup ok. I see signals, when I TX I see signal in the ALC level.

But I get no responses and my direct connections even to startions with good SNR even with some power to be sure never seem to connect.

I have received several messages back: INCOMING CONNECTION REQUEST. Still don't know who that is. I know I have my callsign and grid set.

Here are a few screen shots:
