Fighting to RF, I am wondering if adding a Individual PCI Sound Card to PC o buy a Rig Interface would be improve my signal, lower noise and RF....... What do you think?....What Soundcard or Rig Interface you use with your Flex 6XXX ?
No, using a soundcard of any type only degrades your signal. To use a hardware interface & soundcard, the digital signal has to be converted to analog, passed through the interface, & converted back to digital. The D/A & A/D conversions add a small amount of distortion by their very nature. Using DAX, everything is kept in the digital realm & therefore no distortion due to the conversions. -- 73, Ray, K9DUR
