After testing digimodes into a dummy load as repeating
transmission- can confirm your comments.<br>
<br>
I'm capable of AISO, though not using it. My VAC setup is
highly tweaked though, and I think I'm seeing about 45ms latency. I
was running at quite higher with this setup. A great improvement.<br>
<br>
I was happy before... so does that make more more than happy?<br>
