I think this is a problem on my end, but I don't know how to resolve it. I am aware of the details only because I am a sysop for the remote station and can watch what is happening at both ends. This has happened with other stations I try to connect to, but not all.
When I attempt to make a connection to the remote station from my home base, the remote station hears me and replies. I can hear with my ears the reply, but VarAC doesn't respond. If the remote station initiates a connection request, then VarAC responds as normal. Beacons sent by the remote station (20m today, for example) show SNR -07dB on my end. Beacons sent by my station show SNR -14dB on on the remote station's end. If anything, I should be easily responding to the remote station's replys and the remote station should be struggling to hear me.
Is there a tweak anywhere to improve this?
Not really tracking what you are trying to describe as the issue but it looks like in the screenshots you are using a Flex?? If so make sure all the latency you can remove is removed by using these settings for DIGU. I use a 6500 daily for a couple of years with VarAC with no issues. I also dropped the ComPort emulation and PTT/CAT via TCP/IP CAT.
Missed the settings screenshots.
Band conditions decreased a bit at the time these screenshots were captured, but the behavior was the same. I tried to capture these within the briefest time possible. N5ARC was sending replies at the time NO6GN was attempting to ping.
