SPECTRAN takes some time to process the input signal, maybe three
seconds with your setting. Then the processed signal becomes available
on the line and speaker out of the S/B.
Possibly it is an audio signal re-entering the input of the S/B. I am not
able to explain the frequency difference, however; but it may be due to
the signal processing. I will ask Alberto I2PHD.
But you may try with a local QRSS signal. If the cause is the S/B-software
system it should be easy to detect. Otherwise... echoes from a
trans-dimensional alien mothership?
