I Use the TS-930 and with the RF gain at full and a band loaded with
strong signals there tends to be some mixing of signals from off freq.
However by reducing the RF GAin control it isn't necessary to change the
Audio leval and the AGC doesn't seem to be affected. On 40 / 80 and
sometimes 20 I will add Attentuation also. It really helps on
separating weak CW or SSB signals just by reducing the RF Gain control.
