The Flex radio receives a certain bandwidth of spectrum depending on
the sample rate. It is either 48, 96, or 192khz. That is what you see

usually a few khz. That is what is output to the Flex audio

The suggested operation would be that you hear both your transmitted

the latency interval. In practice the 5K doesn't do this. You might

A VAC feature that can cause accumulating latency is its automatic

it causes.

This is an interesting setup you have. I am running into similar

For best CW results you should try the latest firmware and SVN. Many
