Hi Joe, 

Are you using any VAC (Virtual Audio Cable) software?

Subject: [Flexradio] Flex 3K Audio Buzz 

Ever since having my Flex 3K return from factory service on different 
problem - and the simultaneous upgrade to PSDR 2.1.5- I have been 
experiencing a buzzing sound on received signals. The same buzz is on my 
transmitted signal as well. Sounds almost as if I am running 60 Hz AC on the 
plates the way some amateurs did in the long ago dark ages of the hobby! 

This may occur after the rig/software has been on for only a few minutes . . 
. or it may not occur for several hours. Switching PSDR off then on again 
provides immediate, though temporary, relief - but is inconvenient when in 
QSO mode. The problem is present on both SSB & CW. 

Anyone else seen this problem? Anyone have a solution? 

Thanks- 

Joe, K9OCO
