That's really strange. Never observed that on 1.372. Do you have your
control software sitting active on the async port, when this happens? The
only time I've ever had a problem like this is in the dim past when I tried
to run both N4PY and the Orion front panel at the same time.

I suspect you're hearing the result of the THRESHOLD level being changed
when NR is turned on. The idea is less to eliminate the noise (which can't
really be done perfectly, anyway) than to increase S/N ratio.
