John,
I have been looking at your excellent 500kHz Grabber
and notice that some strong signals are de-sentising
the receiver and causing other weaker signals to show
up less clearly. I belive you are using an AOR AR7030
Rx and I wonder wether you have the AGC on or off ?
I have noticed this effect with some receivers, even with
AGC OFF there is still some control of Rx gain, but had
hoped that the 7030 would not suffer from this defect. Of
course it might be due to some AGC effect in the Spec-
Lab program you are using.
