Hello Stacey

> I think this is purely AGC effect.

Whilst this seems correct, why do the L band uplink stations not suffer the
same way? Despite L band uplink signals as loud as the MB (ie, way louder
than _any_ U band signals), the L band AGC hardly ever moves from 0.7dB
suppression. Meantime as you say the U band AGC is wondering around 10dB
peaking at over 20dB(!) on occasion.

To me this would suggest that the U-band and L-band AGC's are behaving
significantly differently.
