Receiving some 20M RTTY today when the signal was between S7-S9 saw an image
appear on the panadapter on the LSB side of the as the signal level
increased a 3rd image appeared on the USB just outside of the filter
setting. Also noticed with the audio passband set to 1000hz the noise level
outside the audio passband would rise and another image of the received
signal would appear with the signals in the panadapter. Hooked up a signal
generator and was able to duplicate be varying the signal levels. Hope this
helps and doesn't confiuse the problem.
