[Elecraft] AGC

Dave,

That's good advice. I usually keep my AGC THR set to about 18. However,
the higher the threshold, the closer the dynamic range approaches that of
no AGC, but without the danger of overload or hitting the limiter that
will protect your hearing. If that isn't to your liking try dropping it
down to the mid to lower teens.

Also -- don't overlook something as easy as simply reducing your RF Gain
control. As you first begin to reduce it, the results are virtually
identical to what you'll get by raising the ACG THR level -- and it's
right there on the front panel. You may find that's all you need.
