Ok, Tim, it looks like I am in business. The VAC 4.09 shows 48 KHz sampling and my signal looks cleaner. Also thanks to Dave for his hint!

Now Win7 sound devices have a "default" sampling rate and VAC/PowerSDR can not change it for what ever reason. If you look at the VAC sound devices in Windows Control Panel, you will see that they are defaulting at 44.1 KHz (the SR for listening to CDs). If you change the default sampling rate for the two playback and two record VAC device to 48K, then it will show up as the right SR once PowerSDR is running. Ed is right that you should always start PowerSDR first, enable VAC and then start your digi mode program. -Tim -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of David Beumer W0DHB Sent: Saturday, July 03, 2010 5:08 PM To: 'Ed Wilson'; 'flex list'; flexra...@yahoogroups.com Subject: Re: [Flexradio] Sampling Rate, VAC 4.09, and Windows 7 Ed You need to make sure Powersdr is running before firing up DM780 or other digital program otherwise the sample rate of the VAC gets set by the digital program.

I recently upgraded to a Flex-5000 and a new Dell computer running Windows 7, 32-bit. It has taken me some time to get all of the software installed on this new machine, but everything seems to be working fine, at least on CW (SDR 1.18.6). I have been using DM780 Version 5 (Build 2614) for PSK on the Flex-3000 without any trouble. The sampling rate on DM780 is 8K and I set VAC sampling at 48K in SDR 1.18.6. When I check the Control Panel of VAC 4.09 with the Flex-5000 running under Windows 7, it shows a sample rate of 44.1 KHz for the two virtual cables. If I check the Flex-3000 system which runs under Windows XP Professional using the same software setup (different computer), the VAC 4.09 Control Panel shows 48.0 KHz for the sample rate. I have been able to make contacts with the Windows 7/Flex-5000 system on PSK, but the output is not as clean as I would like, so I think that I have a problem. I have tried various sample rates in SDR 1.18.6 to no avail. Any suggestions would be welcome.
