Hi Dave,
I'm using Windows XP on a Quad Core AMD Phenom II x4 965 AM3 Black
Edition CPU running at 3.4Ghz with 4GB RAM.
The system load is never above 5% with everything running, PSDR, VAC,
DDUtil, Fldigi, VOAcap and Band Master.
The audio from VAC is quite poor to say the least, I have been quite
disappointed with my purchase which I made only 2 days ago :(
I'm hoping for a patch fix ASAP otherwise will be looking for a
refund ;)
Cheers!
Mike.

What OS are you running with VAC 4.10 and how many CPU's ?
One of the "improvements" in 4.10 was to spread the VAC
computations over
multi-cores .
I've downloaded my upgrade, but holding off awaiting word from Tim .

Hi Tim,
Thanks for the info.
I have just purchased VAC and have version 4.10.0.2537 and have been
disappointed with it, I thought it was the settings that I was
using, I got
them from the Flex Knowledge Centre.
I've found there are huge delays getting the sound to fldigi for CW
and
PSK31 decoding, seems extremely slow?
I'm running it on a 3.4Ghz Quad Core AMD 965 system which is
showing total
CPU load at <5% for 99% of the time so I know it's not the system
under load
causing the problem :)
On SSB there is a lot of popping and audio drops outs making it almost
unusable, I was about to contact the author and ask for a refund
but I'll
hold fire until you get a result from them and hopefully a patch fix!
Please keep us informed of progress.
Thanks.
Mike.

Subject: [Flexradio] Caution: New VAC version, 4.10 does not work
well
with PowerSDR
Message-ID: <[email protected]>

To all Flexers,
There is a new version of VAC, v4.10 that has been released in the
past few days. Initial testing has indicated that it is *not* a
"drop
in"
replacement for VAC v4.09.
I have been experiencing significant audio drop outs on receive and
(worse) on transmit. Changing sample rates and buffers sizes does
not
seem to make any improvement in the audio quality.
I would strongly recommend that Flexers who utilize VAC *NOT* install
VAC 4.10 until some of these issues can be rectified. If you do plan
to test VAC 4.10, please do so with a dummy load until you are
certain
of the quality of signal you are transmitting.
I have started a correspondence with the VAC developers to help
identify and rectify the significant deficiencies and defects in VAC
4.10 as they pertain to its use with PowerSDR.
One other note to all users. Please do not post on the reflectors
the
URL for VAC upgrades. This is private information and is shared with
only registered users of VAC and not the thousands of users on the
reflectors. The distributors of VAC don't appreciate it and
obviously
get a little upset if it is done since it allows their software to be
easily pirated. If you are a registered user of VAC and you do not
know how to get updates, you must contact the entity you purchased
VAC
from to get that information.
