Ernest, This is not a new problem for me as I have experienced it with the older versions of PSDR, but after I upgraded to 2.2.4 and changed the VAC latency to 20 ms, I was seeing it more often. I am not the only one with the problem as I saw it discussed on the JT65 list a few days ago and I was not the guilty party!
So far, so good with the VAC latency back to 120 ms. I guess that I am wondering if I can eliminate the problem altogether if I increase it beyond 120 ms. That is why I asked what the VAC latency was with the earlier versions of PSDR. Maybe I will get one of the Flex staff to reply sometime next week. I am running Win 7/32 with a quad-core Dell computer. Thanks for your input! I will look for you on JT65.

Win7/64 Dual quad etc... purchased 5 months ago and put together by me. i like you use it on JT65-HF and have had NO problems with either 2.3.5 and the new version. 73, Ernest > Date: Sun, 16 Sep 2012 09:54:11 -0700 > From: [email protected] > To: [email protected]; [email protected] > Subject: [Flexradio] VAC Buffer Latency > > Colleagues, > > PowerSDR 2.4.4 includes a VAC Buffer Latency adjustment with a default value > of 120 ms and, according to the install notes, a possibility of reducing this > to 0 ms with a sufficiently fast computer. > > In trying to troubleshoot some issues here with the digital modes that > utilize VAC (primarily JT65 and PSK31), I was wondering if anyone could shed > some light on the benefits of high or low VAC Latency?
