[QUOTE="Vipersan, post: 797947, member: 325666"] Here is a typical block diagram to show the way agc works in not only a satellite receiver ..but any type of receiver.. I've coloured the relevant area in blue.. The stronger the signal the higher the control voltage generated ..this is then fed back to the first stage of signal amplification ..and used to reduce the gain .. Its a basic neccessity in ALL receivers .. If its not functioning as designed ..the results are what you are experiencing .. Either Software contol is inadequate ..or the receiver/tuner design is flawed...or indeed faulty. To say you need to reduce the signal entering the receiver ..is passing the buck. rgds VS [/QUOTE]
