Numbers station 8992KHz USB, 10/14/2013, 06:33UTC.

Interesting numbers station caught 8992KHz USB, 10/14/2013, 06:33UTC. Caught only last 3min of it. Not strong enought for an S" meter readings but practically no QRM / QRN there. Female ANN repeating numbers and letters in USA English, no accents. What was strange was the vacuum cleaner hose sounding reverb that she had. Stopped at 06:36UTC. Well, I thought that it was a neat catch.
