Andy,
Use the RF attenuator
It is the resource I have used in contests when
operating multiop-multitransmitter.
The S-meter will be less enthusiastic, but the
receiver will work.

Andy and the group,
A thousand and one apologies. I can't even claim a senior moment. In
my rush to a knee jerk reaction I misread AGC as ALC and RF gain as RF
power.. Duuuh!
So, this EHam article is talking about receiving, not transmitting.
Now the statement makes sense. The same is
Thanks Jose and Scott.
So, my original question was related to my observations were that lowering
RF gain on my receiver did range of the waterfall. Apparently this is
related to AGC circuitry being activated . On my radio the disappearance
of weaker signals from the waterfall when a very
On both of my receivers (ICOM 736 and Kenwood TS-2000), with AGC off,

My reading of the article is that turning down the RF gain will reduce
the distortion on a strong signal caused by either the
Turning down the RF gain will reduce the signal below the level that
causes any (or much) AGC action. Always use your slowest AGC setting.
Can someone explain this statement? In my radio, with only an AGC
FAST/SLOW option, reducing the RF gain appeared to may no difference

Where did you see that statement Andy? The thing to turn down until
you have no AGC is the audio drive from the soundcard, NOT the RF
gain. Nothing wrong with turning down the RF gain if you want to run
lower power, but that will not get rid of splatter caused by the AGC.
